RFC 7018 Auto-Discovery VPN Problem Statement and Requirements
 
Authors:V. Manral, S. Hanna.
Date:September 2013
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 7018
This document describes the problem of enabling a large number of systems to communicate directly using IPsec to protect the traffic between them. It then expands on the requirements for such a solution.

Manual configuration of all possible tunnels is too cumbersome in many such cases. In other cases, the IP addresses of endpoints change, or the endpoints may be behind NAT gateways, making static configuration impossible. The Auto-Discovery VPN solution will address these requirements.

RFC 7021 Assessing the Impact of Carrier-Grade NAT on Network Applications
 
Authors:C. Donley, Ed., L. Howard, V. Kuarsingh, J. Berg, J. Doshi.
Date:September 2013
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 7021
NAT444 is an IPv4 extension technology being considered by ServiceProviders as a means to continue offering IPv4 service to customers while transitioning to IPv6. This technology adds an extra Carrier-Grade NAT (CGN) in the Service Provider network, often resulting in two NATs. CableLabs, Time Warner Cable, and Rogers Communications independently tested the impacts of NAT444 on many popular Internet services using a variety of test scenarios, network topologies, and vendor equipment. This document identifies areas where adding a second layer of NAT disrupts the communication channel for commonInternet applications. This document was updated to include theDual-Stack Lite (DS-Lite) impacts also.
 
RFC 7022 Guidelines for Choosing RTP Control Protocol (RTCP) Canonical Names (CNAMEs)
 
Authors:A. Begen, C. Perkins, D. Wing, E. Rescorla.
Date:September 2013
Formats:txt pdf
Obsoletes:RFC 6222
Updates:RFC 3550
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7022
The RTP Control Protocol (RTCP) Canonical Name (CNAME) is a persistent transport-level identifier for an RTP endpoint. While theSynchronization Source (SSRC) identifier of an RTP endpoint may change if a collision is detected or when the RTP application is restarted, its RTCP CNAME is meant to stay unchanged, so that RTP endpoints can be uniquely identified and associated with their RTP media streams.

For proper functionality, RTCP CNAMEs should be unique within the participants of an RTP session. However, the existing guidelines for choosing the RTCP CNAME provided in the RTP standard (RFC 3550) are insufficient to achieve this uniqueness. RFC 6222 was published to update those guidelines to allow endpoints to choose unique RTCPCNAMEs. Unfortunately, later investigations showed that some parts of the new algorithms were unnecessarily complicated and/or ineffective. This document addresses these concerns and replaces RFC6222.

 
RFC 7023 MPLS and Ethernet Operations, Administration, and Maintenance (OAM) Interworking
 
Authors:D. Mohan, Ed., N. Bitar, Ed., A. Sajassi, Ed., S. DeLord, P. Niger, R. Qiu.
Date:October 2013
Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7023
This document specifies the mapping of defect states between EthernetAttachment Circuits (ACs) and associated Ethernet pseudowires (PWs) connected in accordance with the Pseudowire Emulation Edge-to-Edge(PWE3) architecture to realize an end-to-end emulated Ethernet service. It standardizes the behavior of Provider Edges (PEs) with respect to Ethernet PW and AC defects.
 
RFC 7024 Virtual Hub-and-Spoke in BGP/MPLS VPNs
 
Authors:H. Jeng, J. Uttaro, L. Jalil, B. Decraene, Y. Rekhter, R. Aggarwal.
Date:October 2013
Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7024
With BGP/MPLS Virtual Private Networks (VPNs), providing any-to-any connectivity among sites of a given VPN would require each ProviderEdge (PE) router connected to one or more of these sites to hold all the routes of that VPN. The approach described in this document allows the VPN service provider to reduce the number of PE routers that have to maintain all these routes by requiring only a subset of these routers to maintain all these routes.

Furthermore, when PE routers use ingress replication to carry the multicast traffic of VPN customers, the approach described in this document may, under certain circumstances, reduce bandwidth inefficiency associated with ingress replication and redistribute the replication load among PE routers.

 
RFC 7025 Requirements for GMPLS Applications of PCE
 
Authors:T. Otani, K. Ogaki, D. Caviglia, F. Zhang, C. Margaria.
Date:September 2013

RFC 7026 Retiring TLVs from the Associated Channel Header of the MPLS Generic Associated Channel
 
Authors:A. Farrel, S. Bryant.
Date:September 2013
Formats:txt pdf
Updates:RFC 5586
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7026
The MPLS Generic Associated Channel (G-ACh) is a generalization of the applicability of the pseudowire (PW) Associated Channel Header(ACH). RFC 5586 defines the concept of TLV constructs that can be carried in messages on the G-ACh by placing them in the ACH between the fixed header fields and the G-ACh message. These TLVs are calledACH TLVs

No Associated Channel Type yet defined uses an ACH TLV. Furthermore, it is believed that handling TLVs in hardware introduces significant problems to the fast path, and since G-ACh messages are intended to be processed substantially in hardware, the use of ACH TLVs is undesirable.

This document updates RFC 5586 by retiring ACH TLVs and removing the associated registry.

 
RFC 7027 Elliptic Curve Cryptography (ECC) Brainpool Curves for Transport Layer Security (TLS)
 
Authors:J. Merkle, M. Lochter.
Date:October 2013
Formats:txt pdf
Updates:RFC 4492
Status:INFORMATIONAL
DOI:10.17487/RFC 7027
This document specifies the use of several Elliptic CurveCryptography (ECC) Brainpool curves for authentication and key exchange in the Transport Layer Security (TLS) protocol.
 
RFC 7028 Multicast Mobility Routing Optimizations for Proxy Mobile IPv6
 
Authors:JC. Zuniga, LM. Contreras, CJ. Bernardos, S. Jeon, Y. Kim.
Date:September 2013
Formats:txt pdf
Status:EXPERIMENTAL
DOI:10.17487/RFC 7028
This document proposes some experimental enhancements to the base solution to support IP multicasting in a Proxy Mobile IPv6 (PMIPv6) domain. These enhancements include the use of a multicast tree mobility anchor as the topological anchor point for multicast traffic, as well as a direct routing option where the Mobile AccessGateway can provide access to multicast content in the local network.The goal of these enhancements is to provide benefits such as reducing multicast traffic replication and supporting differentPMIPv6 deployment scenarios.
 
RFC 7029 Extensible Authentication Protocol (EAP) Mutual Cryptographic Binding
 
Authors:S. Hartman, M. Wasserman, D. Zhang.
Date:October 2013
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 7029
As the Extensible Authentication Protocol (EAP) evolves, EAP peers rely increasingly on information received from the EAP server. EAP extensions such as channel binding or network posture information are often carried in tunnel methods; peers are likely to rely on this information. Cryptographic binding is a facility described in RFC3748 that protects tunnel methods against man-in-the-middle attacks.However, cryptographic binding focuses on protecting the server rather than the peer. This memo explores attacks possible when the peer is not protected from man-in-the-middle attacks and recommends cryptographic binding based on an Extended Master Session Key, a new form of cryptographic binding that protects both peer and server along with other mitigations.
 
RFC 7030 Enrollment over Secure Transport
 
Authors:M. Pritikin, Ed., P. Yee, Ed., D. Harkins, Ed..
Date:October 2013
Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7030
This document profiles certificate enrollment for clients usingCertificate Management over CMS (CMC) messages over a secure transport. This profile, called Enrollment over Secure Transport(EST), describes a simple, yet functional, certificate management protocol targeting Public Key Infrastructure (PKI) clients that need to acquire client certificates and associated Certification Authority(CA) certificates. It also supports client-generated public/private key pairs as well as key pairs generated by the CA.
 
RFC 7031 DHCPv6 Failover Requirements
 
Authors:T. Mrugalski, K. Kinnear.
Date:September 2013
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 7031
The DHCPv6 protocol, defined in RFC 3315, allows for multiple servers to operate on a single network; however, it does not define any way the servers could share information about currently active clients and their leases. Some sites are interested in running multiple servers in such a way as to provide increased availability in case of server failure. In order for this to work reliably, the cooperating primary and secondary servers must maintain a consistent database of the lease information. RFC 3315 allows for, but does not define, any redundancy or failover mechanisms. This document outlines requirements for DHCPv6 failover, enumerates related problems, and discusses the proposed scope of work to be conducted. This document does not define a DHCPv6 failover protocol.
 
RFC 7032 LDP Downstream-on-Demand in Seamless MPLS
 
Authors:T. Beckhaus, Ed., B. Decraene, K. Tiruveedhula, M. Konstantynowicz, Ed., L. Martini.
Date:October 2013
Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7032
Seamless MPLS design enables a single IP/MPLS network to scale over core, metro, and access parts of a large packet network infrastructure using standardized IP/MPLS protocols. One of the key goals of Seamless MPLS is to meet requirements specific to access networks including high number of devices, device position in network topology, and compute and memory constraints that limit the amount of state access devices can hold. This can be achieved with LDPDownstream-on-Demand (DoD) label advertisement. This document describes LDP DoD use cases and lists required LDP DoD procedures in the context of Seamless MPLS design.

In addition, a new optional TLV type in the LDP Label Request message is defined for fast-up convergence.

RFC 7037 RADIUS Option for the DHCPv6 Relay Agent
 
Authors:L. Yeh, M. Boucadair.
Date:October 2013
Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7037
The DHCPv6 RADIUS option provides a mechanism to exchange authorization and identification information between the DHCPv6 relay agent and DHCPv6 server. This architecture assumes that the NetworkAccess Server (NAS) acts as both a DHCPv6 relay agent and RADIUS client. When receiving messages from the DHCPv6 clients, the NAS consults the RADIUS server and adds the RADIUS response when forwarding the DHCPv6 client's messages to the DHCPv6 server. TheDHCPv6 server then uses that additional information to generate an appropriate response to the DHCPv6 client's requests.
 
RFC 7038 Use of OSPF-MDR in Single-Hop Broadcast Networks
 
Authors:R. Ogier.
Date:October 2013
Formats:txt pdf
Updates:RFC 5614
Status:EXPERIMENTAL
DOI:10.17487/RFC 7038
RFC 5614 (OSPF-MDR) extends OSPF to support mobile ad hoc networks(MANETs) by specifying its operation on the new OSPF interface of type MANET. This document describes the use of OSPF-MDR (MANETDesignated Router) in a single-hop broadcast network, which is a special case of a MANET in which each router is a (one-hop) neighbor of each other router. Unlike an OSPF broadcast interface, such an interface can have a different cost associated with each neighbor.The document includes configuration recommendations and simplified mechanisms that can be used in single-hop broadcast networks.
 
RFC 7039 Source Address Validation Improvement (SAVI) Framework

Date:October 2013
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 7039
Source Address Validation Improvement (SAVI) methods were developed to prevent nodes attached to the same IP link from spoofing each other's IP addresses, so as to complement ingress filtering with finer-grained, standardized IP source address validation. This document is a framework document that describes and motivates the design of the SAVI methods. Particular SAVI methods are described in other documents.
 
RFC 7040 Public IPv4-over-IPv6 Access Network
 
Authors:Y. Cui, J. Wu, P. Wu, O. Vautrin, Y. Lee.
Date:November 2013
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 7040
This document describes a mechanism called Public 4over6, which is designed to provide IPv4 Internet connectivity over an IPv6 access network using global IPv4 addresses. Public 4over6 was developed in the IETF and is in use in some existing deployments but is not recommended for new deployments. Future deployments of similar scenarios should use Lightweight 4over6. Public 4over6 follows theHub and Spoke softwire model and uses an IPv4-in-IPv6 tunnel to forward IPv4 packets over an IPv6 access network. The bidirectionality of the IPv4 communication is achieved by explicitly allocating global non-shared IPv4 addresses to end users and by maintaining IPv4-IPv6 address binding on the border relay. Public4over6 aims to provide uninterrupted IPv4 services to users, likeInternet Content Providers (ICPs), etc., while an operator makes the access network transition to an IPv6-only access network.
 
RFC 7041 Extensions to the Virtual Private LAN Service (VPLS) Provider Edge (PE) Model for Provider Backbone Bridging
 
Authors:F. Balus, Ed., A. Sajassi, Ed., N. Bitar, Ed..
Date:November 2013
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 7041
The IEEE 802.1 Provider Backbone Bridges (PBBs) specification defines an architecture and bridge protocols for interconnection of multipleProvider Bridged Networks (PBNs). Provider backbone bridging was defined by IEEE as a connectionless technology based on multipointVLAN tunnels. PBB can be used to attain better scalability thanProvider Bridges (PBs) in terms of the number of customer MediaAccess Control addresses and the number of service instances that can be supported.

The Virtual Private LAN Service (VPLS) provides a framework for extending Ethernet LAN services, using MPLS tunneling capabilities, through a routed MPLS backbone without running the Rapid SpanningTree Protocol (RSTP) or the Multiple Spanning Tree Protocol (MSTP) across the backbone. As a result, VPLS has been deployed on a large scale in service provider networks.

This document discusses extensions to the VPLS Provider Edge (PE) model required to incorporate desirable PBB components while maintaining the service provider fit of the initial model.

RFC 7043 Resource Records for EUI-48 and EUI-64 Addresses in the DNS
 
Authors:J. Abley.
Date:October 2013
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 7043
48-bit Extended Unique Identifier (EUI-48) and 64-bit Extended UniqueIdentifier (EUI-64) are address formats specified by the IEEE for use in various layer-2 networks, e.g., Ethernet.

This document describes two new DNS resource record types, EUI48 andEUI64, for encoding Ethernet addresses in the DNS.

This document describes potentially severe privacy implications resulting from indiscriminate publication of link-layer addresses in the DNS. EUI-48 or EUI-64 addresses SHOULD NOT be published in the public DNS. This document specifies an interoperable encoding of these address types for use in private DNS namespaces, where the privacy concerns can be constrained and mitigated.

Formats:txt pdf
Status:EXPERIMENTAL
DOI:10.17487/RFC 7046
Group communication services exist in a large variety of flavors and technical implementations at different protocol layers. Multicast data distribution is most efficiently performed on the lowest available layer, but a heterogeneous deployment status of multicast technologies throughout the Internet requires an adaptive service binding at runtime. Today, it is difficult to write an application that runs everywhere and at the same time makes use of the most efficient multicast service available in the network. Facing robustness requirements, developers are frequently forced to use a stable upper-layer protocol provided by the application itself. This document describes a common multicast API that is suitable for transparent communication in underlay and overlay and that grants access to the different flavors of multicast. It proposes an abstract naming scheme that uses multicast URIs, and it discusses mapping mechanisms between different namespaces and distribution technologies. Additionally, this document describes the application of this API for building gateways that interconnect current MulticastDomains throughout the Internet. It reports on an implementation of the programming Interface, including service middleware. This document is a product of the Scalable Adaptive Multicast (SAM)Research Group.

The Open vSwitch project includes open-source OVSDB client and server implementations.
 
RFC 7048 Neighbor Unreachability Detection Is Too Impatient
 
Authors:E. Nordmark, I. Gashinsky.
Date:January 2014
Formats:txt pdf
Updates:RFC 4861
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7048
IPv6 Neighbor Discovery includes Neighbor Unreachability Detection.That function is very useful when a host has an alternative neighbor-- for instance, when there are multiple default routers -- since it allows the host to switch to the alternative neighbor in a short time. By default, this time is 3 seconds after the node starts probing. However, if there are no alternative neighbors, this timeout behavior is far too impatient. This document specifies relaxed rules for Neighbor Discovery retransmissions that allow an implementation to choose different timeout behavior based on whether or not there are alternative neighbors. This document updates RFC4861.

Status:PROPOSED STANDARD
DOI:10.17487/RFC 7050
This document describes a method for detecting the presence of DNS64 and for learning the IPv6 prefix used for protocol translation on an access network. The method depends on the existence of a well-knownIPv4-only fully qualified domain name "ipv4only.arpa.". The information learned enables nodes to perform local IPv6 address synthesis and to potentially avoid NAT64 on dual-stack and multi- interface deployments.

Hosts and applications may benefit from learning if an IPv6 address is synthesized and if NAT64 and DNS64 are present in a network. This document analyzes all proposed solutions (known at the time of writing) for communicating whether the synthesis is taking place, what address format was used, and what IPv6 prefix was used by theNAT64 and DNS64. These solutions enable both NAT64 avoidance and local IPv6 address synthesis. The document concludes by recommending the standardization of the approach based on heuristic discovery.

Updates:RFC 4960
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7053
This document updates RFC 4960 by defining a method for the sender of a DATA chunk to indicate that the corresponding SelectiveAcknowledgment (SACK) chunk should be sent back immediately and should not be delayed. It is done by specifying a bit in the DATA chunk header, called the (I)mmediate bit, which can get set by either the Stream Control Transmission Protocol (SCTP) implementation or the application using an SCTP stack. Since unknown flags in chunk headers are ignored by SCTP implementations, this extension does not introduce any interoperability problems.

As the deployment of third and fourth generation cellular networks progresses, a large number of cellular hosts are being connected to the Internet. Standardization organizations have made the InternetProtocol version 6 (IPv6) mandatory in their specifications.However, the concept of IPv6 covers many aspects and numerous specifications. In addition, the characteristics of cellular links in terms of bandwidth, cost, and delay put special requirements on how IPv6 is used. This document considers IPv6 for cellular hosts that attach to the General Packet Radio Service (GPRS), UniversalMobile Telecommunications System (UMTS), or Evolved Packet System(EPS) networks (hereafter collectively referred to as ThirdGeneration Partnership Project (3GPP) networks). This document also lists specific IPv6 functionalities that need to be implemented in addition to what is already prescribed in the IPv6 Node Requirements document (RFC 6434). It also discusses some issues related to the use of these components when operating in these networks. This document obsoletes RFC 3316.

Edge TRILL (Transparent Interconnection of Lots of Links) switches currently learn the mapping between MAC (Media Access Control) addresses and their egress TRILL switch by observing the data packets they ingress or egress or by the TRILL ESADI (End-Station AddressDistribution Information) protocol. When an ingress TRILL switch receives a data frame for a destination address (MAC&Label) that the switch does not know, the data frame is flooded within the frame'sData Label across the TRILL campus.

This document describes the framework for using directory services to assist edge TRILL switches in reducing multi-destination frames, particularly unknown unicast frames flooding, and ARP/ND (AddressResolution Protocol / Neighbor Discovery), thus improving TRILL network scalability and security.

Status:INFORMATIONAL
DOI:10.17487/RFC 7068
When a Diameter server or agent becomes overloaded, it needs to be able to gracefully reduce its load, typically by advising clients to reduce traffic for some period of time. Otherwise, it must continue to expend resources parsing and responding to Diameter messages, possibly resulting in a progressively severe overload condition. The existing Diameter mechanisms are not sufficient for managing overload conditions. This document describes the limitations of the existing mechanisms. Requirements for new overload management mechanisms are also provided.

Content distribution applications, such as those employing peer-to- peer (P2P) technologies, are widely used on the Internet and make up a large portion of the traffic in many networks. Often, however, content distribution applications use network resources inefficiently. One way to improve efficiency is to introduce storage capabilities within the network and enable cooperation between end- host and in-network content distribution mechanisms. This is the capability provided by a DECoupled Application Data Enroute (DECADE) system, which is introduced in this document. DECADE enables applications to take advantage of in-network storage when distributing data objects as opposed to using solely end-to-end resources. This document presents the underlying principles and key functionalities of such a system and illustrates operation through a set of examples.

DOI:10.17487/RFC 7074
GMPLS provides control for multiple switching technologies and for hierarchical switching within a technology. GMPLS routing and signaling use common values to indicate the type of switching technology. These values are carried in routing protocols via theSwitching Capability field, and in signaling protocols via theSwitching Type field. While the values used in these fields are the primary indicators of the technology and hierarchy level being controlled, the values are not consistently defined and used across the different technologies supported by GMPLS. This document is intended to resolve the inconsistent definition and use of theSwitching Capability and Type fields by narrowly scoping the meaning and use of the fields. This document updates all documents that use the GMPLS Switching Capability and Types fields, in particular RFCs3471, 4202, 4203, and 5307.

Date:November 2013
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 7076
The Secure Shell (SSH) Public Key Subsystem protocol defines a key distribution protocol that is limited to provisioning an SSH server with a user's public keys. This document describes a new protocol that builds on the protocol defined in RFC 4819 to allow the provisioning of keys and certificates to a server using the SSH transport.

The new protocol allows the calling client to organize keys and certificates in different namespaces on a server. These namespaces can be used by the server to allow a client to configure any application running on the server (e.g., SSH, Key ManagementInteroperability Protocol (KMIP), Simple Network Management Protocol(SNMP)).

The new protocol provides a server-independent mechanism for clients to add public keys, remove public keys, add certificates, remove certificates, and list the current set of keys and certificates known by the server by namespace (e.g., list all public keys in the SSH namespace).

Rights to manage keys and certificates in a particular namespace are specific and limited to the authorized user and are defined as part of the server's implementation. The described protocol is backward compatible to version 2 defined by RFC 4819.

The IETF Pseudowire Emulation Edge-to-Edge (PWE3) working group has defined many encapsulations of various layer 1 and layer 2 service- specific PDUs and circuit data. In most of these encapsulations, use of the Pseudowire (PW) Control Word is required. However, there are several encapsulations for which the Control Word is optional, and this optionality has been seen in practice to possibly introduce interoperability concerns between multiple implementations of those encapsulations. This survey of the Pseudowire / Virtual CircuitConnectivity Verification (VCCV) user community was conducted to determine implementation trends and the possibility of always mandating the Control Word.

DOI:10.17487/RFC 7081
This document suggests some strategies for the combined use of theSession Initiation Protocol (SIP) and the Extensible Messaging andPresence Protocol (XMPP) both in user-oriented clients and in deployed servers. Such strategies, which mainly consist of configuration changes and minimal software modifications to existing clients and servers, aim to provide a single, full-featured, real- time communication service by using complementary subsets of features from SIP and from XMPP. Typically, such subsets consist of telephony capabilities from SIP and instant messaging and presence capabilities from XMPP. This document does not define any new protocols or syntax for either SIP or XMPP and, by intent, does not attempt to standardize "best current practices". Instead, it merely aims to provide practical guidance to those who are interested in the combined use of SIP and XMPP for real-time communication.
 
RFC 7082 Indication of Conference Focus Support for the Centralized Conferencing Manipulation Protocol (CCMP)

Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 7082
The Centralized Conferencing Manipulation Protocol (CCMP) document(RFC 6503) defines a way for a client to discover a conference control server that supports CCMP. However, it does not define a way for a client involved in a conference to determine if the conference focus supports CCMP. This information would allow a CCMP-enabled client that joins a conference using SIP to also register for theCentralized Conferencing (XCON) conference event package and take advantage of CCMP operations on the conference.

This document describes two mechanisms, depending upon the need of the User Agent (UA), to address the above limitation. The first mechanism uses the Call-Info header field, and the second mechanism defines a new value for the "purpose" header field parameter in the<service-uris&rt; element in the SIP conferencing event package.

Status:INFORMATIONAL
DOI:10.17487/RFC 7085
Recent statements from the Internet Architecture Board (IAB) and theInternet Corporation of Assigned Names and Numbers (ICANN) Security and Stability Advisory Committee have focused on the problems that the DNS is likely to experience with top-level domains (TLDs) that contain address records (so-called "dotless domains"). In order to help researchers determine the extent of the issues with dotless domains, this document lists the current dotless TLDs and gives a script for finding them. This document lists data about dotless TLDs but does not address the policy and technology issues other than to point to the statements of others.

Status:INFORMATIONAL
DOI:10.17487/RFC 7087
The MPLS Transport Profile (MPLS-TP) is based on a profile of theMPLS and Pseudowire (PW) procedures as specified in the MPLS TrafficEngineering (MPLS-TE), PW, and Multi-Segment Pseudowire (MS-PW) architectures developed by the Internet Engineering Task Force(IETF). The International Telecommunication Union TelecommunicationStandardization Sector (ITU-T) has specified a Transport Network architecture.

This document provides a thesaurus for the interpretation of MPLS-TP terminology within the context of the ITU-T Transport NetworkRecommendations.

It is important to note that MPLS-TP is applicable in a wider set of contexts than just Transport Networks. The definitions presented in this document do not provide exclusive or complete interpretations ofMPLS-TP concepts. This document simply allows the MPLS-TP terms to be applied within the Transport Network context.

 
RFC 7088 Session Initiation Protocol Service Example -- Music on Hold
 
Authors:D. Worley.
Date:February 2014
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 7088
"Music on hold" is one of the features of telephone systems that is most desired by buyers of business telephone systems. Music on hold means that when one party to a call has the call "on hold", that party's telephone provides an audio stream (often music) to be heard by the other party. Architectural features of SIP make it difficult to implement music on hold in a way that is fully standards- compliant. The implementation of music on hold described in this document is fully effective, is standards-compliant, and has a number of advantages over the methods previously documented. In particular, it is less likely to produce peculiar user interface effects and more likely to work in systems that perform authentication than the music- on-hold method described in Section 2.3 of RFC 5359.
 
RFC 7089 HTTP Framework for Time-Based Access to Resource States -- Memento
 
Authors:H. Van de Sompel, M. Nelson, R. Sanderson.
Date:December 2013
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 7089
The HTTP-based Memento framework bridges the present and past Web.It facilitates obtaining representations of prior states of a given resource by introducing datetime negotiation and TimeMaps. Datetime negotiation is a variation on content negotiation that leverages the given resource's URI and a user agent's preferred datetime. TimeMaps are lists that enumerate URIs of resources that encapsulate prior states of the given resource. The framework also facilitates recognizing a resource that encapsulates a frozen prior state of another resource.
 
RFC 7090 Public Safety Answering Point (PSAP) Callback
 
Authors:H. Schulzrinne, H. Tschofenig, C. Holmberg, M. Patel.

Status:PROPOSED STANDARD
DOI:10.17487/RFC 7090
After an emergency call is completed (terminated either prematurely by the emergency caller or normally by the call taker), the call taker may feel the need for further communication. For example, the call may have been dropped by accident without the call taker having sufficient information about the current state of an accident victim.A call taker may trigger a callback to the emergency caller using the contact information provided with the initial emergency call. This callback could, under certain circumstances, be treated like any other call and, as a consequence, it may get blocked by authorization policies or may get forwarded to an answering machine.

The IETF emergency services architecture specification already offers a solution approach for allowing Public Safety Answering Point (PSAP) callbacks to bypass authorization policies in order to reach the caller without unnecessary delays. Unfortunately, the specified mechanism only supports limited scenarios. This document discusses shortcomings of the current mechanisms and illustrates additional scenarios where better-than-normal call treatment behavior would be desirable. We describe a solution based on a new header field value for the SIP Priority header field, called "psap-callback", to markPSAP callbacks.

RFC 7092 A Taxonomy of Session Initiation Protocol (SIP) Back-to-Back User Agents
 
Authors:H. Kaplan, V. Pascual.
Date:December 2013
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 7092
In many SIP deployments, SIP entities exist in the SIP signaling path between the originating and final terminating endpoints, which go beyond the definition of a SIP proxy, performing functions not defined in Standards Track RFCs. The only term for such devices provided in RFC 3261 is for a Back-to-Back User Agent (B2BUA), which is defined as the logical concatenation of a SIP User Agent Server(UAS) and User Agent Client (UAC).

There are numerous types of SIP B2BUAs performing different roles in different ways; for example, IP Private Branch Exchanges (IPBXs),Session Border Controllers (SBCs), and Application Servers (ASs).This document identifies several common B2BUA roles in order to provide taxonomy other documents can use and reference.
