RFC 7305 Report from the IAB Workshop on Internet Technology Adoption and Transition (ITAT)
 
Authors:E. Lear, Ed..
Date:July 2014
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 7305
This document provides an overview of a workshop held by the InternetArchitecture Board (IAB) on Internet Technology Adoption andTransition (ITAT). The workshop was hosted by the University ofCambridge on December 4th and 5th of 2013 in Cambridge, UK. The goal of the workshop was to facilitate adoption of Internet protocols, through examination of a variety of economic models, with particular emphasis at the waist of the hourglass (e.g., the middle of the protocol stack). This report summarizes contributions and discussions. As the topics were wide ranging, there is no single set of recommendations for IETF participants to pursue at this time.Instead, in the classic sense of early research, the workshop noted areas that deserve further exploration.

Note that this document is a report on the proceedings of the workshop. The views and positions documented in this report are those of the workshop participants and do not necessarily reflect IAB views and positions.

RFC 7309 Redundancy Mechanism for Inter-domain VPLS Service
 
Authors:Z. Liu, L. Jin, R. Chen, D. Cai, S. Salam.
Date:July 2014
Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7309
In many existing Virtual Private LAN Service (VPLS) inter-domain deployments (based on RFC 4762), pseudowire (PW) connectivity offers no Provider Edge (PE) node redundancy, or offers PE node redundancy with only a single domain. This deployment approach incurs a high risk of service interruption, since at least one domain will not offer PE node redundancy. This document describes an inter-domainVPLS solution that provides PE node redundancy across domains.
 
RFC 7310 RTP Payload Format for Standard apt-X and Enhanced apt-X Codecs
 
Authors:J. Lindsay, H. Foerster.

RFC 7311 The Accumulated IGP Metric Attribute for BGP
 
Authors:P. Mohapatra, R. Fernando, E. Rosen, J. Uttaro.
Date:August 2014
Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7311
Routing protocols that have been designed to run within a single administrative domain (IGPs) generally do so by assigning a metric to each link and then choosing, as the installed path between two nodes, the path for which the total distance (sum of the metric of each link along the path) is minimized. BGP, designed to provide routing over a large number of independent administrative domains (autonomous systems), does not make its path-selection decisions through the use of a metric. It is generally recognized that any attempt to do so would incur significant scalability problems as well as inter- administration coordination problems. However, there are deployments in which a single administration runs several contiguous BGP networks. In such cases, it can be desirable, within that single administrative domain, for BGP to select paths based on a metric, just as an IGP would do. The purpose of this document is to provide a specification for doing so.
 
RFC 7312 Advanced Stream and Sampling Framework for IP Performance Metrics (IPPM)
 
Authors:J. Fabini, A. Morton.
Date:August 2014
Formats:txt pdf
Updates:RFC 2330
Status:INFORMATIONAL
DOI:10.17487/RFC 7312
To obtain repeatable results in modern networks, test descriptions need an expanded stream parameter framework that also augments aspects specified as Type-P for test packets. This memo updates theIP Performance Metrics (IPPM) Framework, RFC 2330, with advanced considerations for measurement methodology and testing. The existing framework mostly assumes deterministic connectivity, and that a single test stream will represent the characteristics of the path when it is aggregated with other flows. Networks have evolved and test stream descriptions must evolve with them; otherwise, unexpected network features may dominate the measured performance. This memo describes new stream parameters for both network characterization and support of application design using IPPM metrics.
 
RFC 7313 Enhanced Route Refresh Capability for BGP-4
 
Authors:K. Patel, E. Chen, B. Venkatachalapathy.

RFC 7319 IANA Considerations for Connectivity Fault Management (CFM) Code Points
 
Authors:D. Eastlake 3rd.
Date:July 2014
Formats:txt pdf
Also:BCP 0191
Status:BEST CURRENT PRACTICE
DOI:10.17487/RFC 7319
IEEE 802.1 has specified Connectivity Fault Management (CFM)Operations, Administration, and Maintenance (OAM) facilities. CFM messages are structured with an OpCode field and have provision for the inclusion of TLV-structured information. IEEE 802.1 has allocated blocks of CFM OpCodes and TLV Types to the IETF.

RFC 7320 URI Design and Ownership
 
Authors:M. Nottingham.
Date:July 2014
Formats:txt pdf
Updates:RFC 3986
Also:BCP 0190
Status:BEST CURRENT PRACTICE
DOI:10.17487/RFC 7320
Section 1.1.1 of RFC 3986 defines URI syntax as "a federated and extensible naming system wherein each scheme's specification may further restrict the syntax and semantics of identifiers using that scheme." In other words, the structure of a URI is defined by its scheme. While it is common for schemes to further delegate their substructure to the URI's owner, publishing independent standards that mandate particular forms of URI substructure is inappropriate, because that essentially usurps ownership. This document further describes this problematic practice and provides some acceptable alternatives for use in standards.
 
RFC 7321 Cryptographic Algorithm Implementation Requirements and Usage Guidance for Encapsulating Security Payload (ESP) and Authentication Header (AH)
 
Authors:D. McGrew, P. Hoffman.
Date:August 2014
Formats:txt pdf
Obsoletes:RFC 4835
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7321
This document updates the Cryptographic Algorithm ImplementationRequirements for the Encapsulating Security Payload (ESP) andAuthentication Header (AH). It also adds usage guidance to help in the selection of these algorithms.

ESP and AH protocols make use of various cryptographic algorithms to provide confidentiality and/or data origin authentication to protected data communications in the IP Security (IPsec) architecture. To ensure interoperability between disparate implementations, the IPsec standard specifies a set of mandatory-to- implement algorithms. This document specifies the current set of mandatory-to-implement algorithms for ESP and AH, specifies algorithms that should be implemented because they may be promoted to mandatory at some future time, and also recommends against the implementation of some obsolete algorithms. Usage guidance is also provided to help the user of ESP and AH best achieve their security goals through appropriate choices of cryptographic algorithms.

This document obsoletes RFC 4835.

EnergyObjects can be monitored and controlled with respect to power, PowerState, energy, demand, Power Attributes, and battery. Additionally, the framework models relationships and capabilities between EnergyObjects.
 
RFC 7328 Writing I-Ds and RFCs Using Pandoc and a Bit of XML
 
Authors:R. Gieben.
Date:August 2014
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 7328
This document presents a technique for using a Markdown syntax variant, called Pandoc, and a bit of XML (as defined in RFC 2629) as a source format for documents that are Internet-Drafts (I-Ds) orRFCs.

The goal of this technique (which is called Pandoc2rfc) is to let an author of an I-D focus on the main body of text without being distracted too much by XML tags; however, it does not alleviate the need to typeset some files in XML.

 
RFC 7329 A Session Identifier for the Session Initiation Protocol (SIP)
 
Authors:H. Kaplan.
Date:August 2014
Formats:txt pdf
Obsoleted by:RFC 7989
Status:INFORMATIONAL
DOI:10.17487/RFC 7329
There is a need for having a globally unique session identifier for the same SIP session that can be consistently maintained across SIPProxies, Back-to-Back User Agents (B2BUAs), and other SIP middleboxes, for the purpose of troubleshooting. This document proposes a new SIP header to carry such a value: Session-ID.

The mechanism defined in this document has been widely deployed, and is being followed in a backward-compatible fashion for a newStandards Track document produced by the INSIPID Working Group.

Date:August 2014
Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7332
SIP Back-to-Back User Agents (B2BUAs) can cause unending SIP request routing loops because, as User Agent Clients, they can generate SIP requests with new Max-Forwards values. This document discusses the difficulties associated with loop detection for B2BUAs and the requirements for them to prevent infinite loops.
 
RFC 7333 Requirements for Distributed Mobility Management
 
Authors:H. Chan, Ed., D. Liu, P. Seite, H. Yokota, J. Korhonen.
Date:August 2014
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 7333
This document defines the requirements for Distributed MobilityManagement (DMM) at the network layer. The hierarchical structure in traditional wireless networks has led primarily to centrally deployed mobility anchors. As some wireless networks are evolving away from the hierarchical structure, it can be useful to have a distributed model for mobility management in which traffic does not need to traverse centrally deployed mobility anchors far from the optimal route. The motivation and the problems addressed by each requirement are also described.
 
RFC 7334 PCE-Based Computation Procedure to Compute Shortest Constrained Point-to-Multipoint (P2MP) Inter-Domain Traffic Engineering Label Switched Paths
 
Authors:Q. Zhao, D. Dhody, D. King, Z. Ali, R. Casellas.
Date:August 2014
Formats:txt pdf
Status:EXPERIMENTAL
DOI:10.17487/RFC 7334
The ability to compute paths for constrained point-to-multipoint(P2MP) Traffic Engineering Label Switched Paths (TE LSPs) across multiple domains has been identified as a key requirement for the deployment of P2MP services in MPLS- and GMPLS-controlled networks.The Path Computation Element (PCE) has been recognized as an appropriate technology for the determination of inter-domain paths ofP2MP TE LSPs.

This document describes an experiment to provide procedures and extensions to the PCE Communication Protocol (PCEP) for the computation of inter-domain paths for P2MP TE LSPs.

The purpose of the framework is to provide an overall picture of the problem space of CDNI and to describe the relationships among the various components necessary to interconnectCDNs. CDNI requires the specification of interfaces and mechanisms to address issues such as request routing, distribution metadata exchange, and logging information exchange across CDNs. The intent of this document is to outline what each interface needs to accomplish and to describe how these interfaces and mechanisms fit together, while leaving their detailed specification to other documents. This document, in combination with RFC 6707, obsoletesRFC 3466.
 
RFC 7337 Content Distribution Network Interconnection (CDNI) Requirements
 
Authors:K. Leung, Ed., Y. Lee, Ed..
Date:August 2014
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 7337
Content delivery is frequently provided by specifically architected and provisioned Content Delivery Networks (CDNs). As a result of significant growth in content delivered over IP networks, existingCDN providers are scaling up their infrastructure. Many NetworkService Providers (NSPs) and Enterprise Service Providers (ESPs) are also deploying their own CDNs. To deliver contents from the ContentService Provider (CSP) to end users, the contents may traverse across multiple CDNs. This creates a need for interconnecting (previously) standalone CDNs so that they can collectively act as a single delivery platform from the CSP to the end users.

The goal of the present document is to outline the requirements for the solution and interfaces to be specified by the CDNI working group.

 
RFC 7338 Requirements and Framework for Point-to-Multipoint Pseudowires over MPLS Packet Switched Networks
 
Authors:F. Jounay, Ed., Y. Kamite, Ed., G. Heron, M. Bocci.
Date:September 2014
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 7338
This document presents a set of requirements and a framework for providing a point-to-multipoint pseudowire (PW) over MPLS PacketSwitched Networks. The requirements identified in this document are related to architecture, signaling, and maintenance aspects of point- to-multipoint PW operation. They are proposed as guidelines for the standardization of such mechanisms. Among other potential applications, point-to-multipoint PWs can be used to optimize the support of multicast Layer 2 services (Virtual Private LAN Service and Virtual Private Multicast Service).
 
RFC 7339 Session Initiation Protocol (SIP) Overload Control
 
Authors:V. Gurbani, Ed., V. Hilt, H. Schulzrinne.
Date:September 2014
Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7339
Overload occurs in Session Initiation Protocol (SIP) networks whenSIP servers have insufficient resources to handle all the SIP messages they receive. Even though the SIP protocol provides a limited overload control mechanism through its 503 (ServiceUnavailable) response code, SIP servers are still vulnerable to overload. This document defines the behavior of SIP servers involved in overload control and also specifies a loss-based overload scheme for SIP.
 
RFC 7340 Secure Telephone Identity Problem Statement and Requirements
 
Authors:J. Peterson, H. Schulzrinne, H. Tschofenig.
Date:September 2014
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 7340
Over the past decade, Voice over IP (VoIP) systems based on SIP have replaced many traditional telephony deployments. Interworking VoIP systems with the traditional telephone network has reduced the overall level of calling party number and Caller ID assurances by granting attackers new and inexpensive tools to impersonate or obscure calling party numbers when orchestrating bulk commercial calling schemes, hacking voicemail boxes, or even circumventing multi-factor authentication systems trusted by banks. Despite previous attempts to provide a secure assurance of the origin of SIP communications, we still lack effective standards for identifying the calling party in a VoIP session. This document examines the reasons why providing identity for telephone numbers on the Internet has proven so difficult and shows how changes in the last decade may provide us with new strategies for attaching a secure identity to SIP sessions. It also gives high-level requirements for a solution in this space.
 
RFC 7341 DHCPv4-over-DHCPv6 (DHCP 4o6) Transport
 
Authors:Q. Sun, Y. Cui, M. Siodelski, S. Krishnan, I. Farrer.
Date:August 2014
Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7341
IPv4 connectivity is still needed as networks migrate towards IPv6.Users require IPv4 configuration even if the uplink to their service provider supports IPv6 only. This document describes a mechanism for obtaining IPv4 configuration information dynamically in IPv6 networks by carrying DHCPv4 messages over DHCPv6 transport. Two new DHCPv6 messages and two new DHCPv6 options are defined for this purpose.

RFC 7343 An IPv6 Prefix for Overlay Routable Cryptographic Hash Identifiers Version 2 (ORCHIDv2)
 
Authors:J. Laganier, F. Dupont.
Date:September 2014
Formats:txt pdf
Obsoletes:RFC 4843
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7343
This document specifies an updated Overlay Routable CryptographicHash Identifiers (ORCHID) format that obsoletes that in RFC 4843.These identifiers are intended to be used as endpoint identifiers at applications and Application Programming Interfaces (APIs) and not as identifiers for network location at the IP layer, i.e., locators.They are designed to appear as application-layer entities and at the existing IPv6 APIs, but they should not appear in actual IPv6 headers. To make them more like regular IPv6 addresses, they are expected to be routable at an overlay level. Consequently, while they are considered non-routable addresses from the IPv6-layer perspective, all existing IPv6 applications are expected to be able to use them in a manner compatible with current IPv6 addresses.

The Overlay Routable Cryptographic Hash Identifiers originally defined in RFC 4843 lacked a mechanism for cryptographic algorithm agility. The updated ORCHID format specified in this document removes this limitation by encoding, in the identifier itself, an index to the suite of cryptographic algorithms in use.

RFC 7359 Layer 3 Virtual Private Network (VPN) Tunnel Traffic Leakages in Dual-Stack Hosts/Networks
 
Authors:F. Gont.
Date:August 2014
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 7359
The subtle way in which the IPv6 and IPv4 protocols coexist in typical networks, together with the lack of proper IPv6 support in popular Virtual Private Network (VPN) tunnel products, may inadvertently result in VPN tunnel traffic leakages. That is, traffic meant to be transferred over an encrypted and integrity- protected VPN tunnel may leak out of such a tunnel and be sent in the clear on the local network towards the final destination. This document discusses some scenarios in which such VPN tunnel traffic leakages may occur as a result of employing IPv6-unaware VPN software. Additionally, this document offers possible mitigations for this issue.
 
RFC 7360 Datagram Transport Layer Security (DTLS) as a Transport Layer for RADIUS
 
Authors:A. DeKok.

Formats:txt pdf
Status:EXPERIMENTAL
DOI:10.17487/RFC 7360
The RADIUS protocol defined in RFC 2865 has limited support for authentication and encryption of RADIUS packets. The protocol transports data in the clear, although some parts of the packets can have obfuscated content. Packets may be replayed verbatim by an attacker, and client-server authentication is based on fixed shared secrets. This document specifies how the Datagram Transport LayerSecurity (DTLS) protocol may be used as a fix for these problems. It also describes how implementations of this proposal can coexist with current RADIUS systems.
 
RFC 7361 LDP Extensions for Optimized MAC Address Withdrawal in a Hierarchical Virtual Private LAN Service (H-VPLS)

RFC 4762 describes a mechanism to remove or unlearn Media AccessControl (MAC) addresses that have been dynamically learned in aVirtual Private LAN Service (VPLS) instance for faster convergence on topology changes. The procedure also removes MAC addresses in theVPLS that do not require relearning due to such topology changes.This document defines an enhancement to the MAC address withdraw procedure with an empty MAC list (RFC 4762); this enhancement enables a Provider Edge (PE) device to remove only the MAC addresses that need to be relearned. Additional extensions to RFC 4762 MAC withdraw procedures are specified to provide an optimized MAC flushing for theProvider Backbone Bridging (PBB) VPLS specified in RFC 7041.
 
RFC 7362 Latching: Hosted NAT Traversal (HNT) for Media in Real-Time Communication
 
Authors:E. Ivov, H. Kaplan, D. Wing.
Date:September 2014
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 7362
This document describes the behavior of signaling intermediaries inReal-Time Communication (RTC) deployments, sometimes referred to asSession Border Controllers (SBCs), when performing Hosted NATTraversal (HNT). HNT is a set of mechanisms, such as media relaying and latching, that such intermediaries use to enable other RTC devices behind NATs to communicate with each other.

This document is non-normative and is only written to explain HNT in order to provide a reference to the Internet community and an informative description to manufacturers and users.

Latching, which is one of the HNT components, has a number of security issues covered here. Because of those, and unless all security considerations explained here are taken into account and solved, the IETF advises against use of the latching mechanism over the Internet and recommends other solutions, such as the InteractiveConnectivity Establishment (ICE) protocol.

RFC 7364 Problem Statement: Overlays for Network Virtualization
 
Authors:T. Narten, Ed., E. Gray, Ed., D. Black, L. Fang, L. Kreeger, M. Napierala.
Date:October 2014
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 7364
This document describes issues associated with providing multi- tenancy in large data center networks and how these issues may be addressed using an overlay-based network virtualization approach. A key multi-tenancy requirement is traffic isolation so that one tenant's traffic is not visible to any other tenant. Another requirement is address space isolation so that different tenants can use the same address space within different virtual networks.Traffic and address space isolation is achieved by assigning one or more virtual networks to each tenant, where traffic within a virtual network can only cross into another virtual network in a controlled fashion (e.g., via a configured router and/or a security gateway).Additional functionality is required to provision virtual networks, associating a virtual machine's network interface(s) with the appropriate virtual network and maintaining that association as the virtual machine is activated, migrated, and/or deactivated. Use of an overlay-based approach enables scalable deployment on large network infrastructures.

Enterprise network administrators worldwide are in various stages of preparing for or deploying IPv6 into their networks. The administrators face different challenges than operators of Internet access providers and have reasons for different priorities. The overall problem for many administrators will be to offer Internet- facing services over IPv6 while continuing to support IPv4, and while introducing IPv6 access within the enterprise IT network. The overall transition will take most networks from an IPv4-only environment to a dual-stack network environment and eventually anIPv6-only operating mode. This document helps provide a framework for enterprise network architects or administrators who may be faced with many of these challenges as they consider their IPv6 support strategies.

RFC 7389 Separation of Control and User Plane for Proxy Mobile IPv6
 
Authors:R. Wakikawa, R. Pazhyannur, S. Gundavelli, C. Perkins.
Date:October 2014
Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7389
This document specifies a method to split the control plane (CP) and user plane (UP) for a network infrastructure based on Proxy MobileIPv6 (PMIPv6). Existing specifications allow a mobile access gateway(MAG) to separate its control and user plane using the AlternateCare-of Address mobility option for IPv6 or Alternate IPv4 Care-ofAddress option for IPv4. However, the current specification does not provide any mechanism allowing the local mobility anchor (LMA) to perform an analogous functional split. To remedy that shortcoming, this document specifies a mobility option enabling an LMA to provide an alternate LMA address to be used for the bidirectional user-plane traffic between the MAG and LMA. With this new option, an LMA will be able to use an IP address for its user plane that is different than the IP address used for the control plane.
 
RFC 7390 Group Communication for the Constrained Application Protocol (CoAP)
 
Authors:A. Rahman, Ed., E. Dijk, Ed..
Date:October 2014
Formats:txt pdf
Status:EXPERIMENTAL
DOI:10.17487/RFC 7390
The Constrained Application Protocol (CoAP) is a specialized web transfer protocol for constrained devices and constrained networks.It is anticipated that constrained devices will often naturally operate in groups (e.g., in a building automation scenario, all lights in a given room may need to be switched on/off as a group).This specification defines how CoAP should be used in a group communication context. An approach for using CoAP on top of IP multicast is detailed based on existing CoAP functionality as well as new features introduced in this specification. Also, various use cases and corresponding protocol flows are provided to illustrate important concepts. Finally, guidance is provided for deployment in various network topologies.
 
RFC 7391 Forwarding and Control Element Separation (ForCES) Protocol Extensions
 
Authors:J. Hadi Salim.
Date:October 2014
Formats:txt pdf
Updates:RFC 5810, RFC 7121
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7391
Experience in implementing and deploying the Forwarding and ControlElement Separation (ForCES) architecture has demonstrated the need for a few small extensions both to ease programmability and to improve wire efficiency of some transactions. The ForCES protocol is extended with a table range operation and a new extension for error handling. This document updates the semantics in RFCs 5810 and 7121 to achieve that end goal.
 
RFC 7392 Explicit Path Routing for Dynamic Multi-Segment Pseudowires
 
Authors:P. Dutta, M. Bocci, L. Martini.
Date:December 2014
Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7392
When set up through an explicit path, dynamic Multi-SegmentPseudowires (MS-PWs) may be required to provide a simple solution for1:1 protection with diverse primary and backup MS-PWs for a service, or to enable controlled signaling (strict or loose) for special MS-PWs. This document specifies the extensions and procedures required to enable dynamic MS-PWs to be established along explicit paths.
 
RFC 7393 Using the Port Control Protocol (PCP) to Update Dynamic DNS

Both issues and possible solutions are documented in this memo.
 
RFC 7394 Definition of Time to Live TLV for LSP-Ping Mechanisms
 
Authors:S. Boutros, S. Sivabalan, G. Swallow, S. Saxena, V. Manral, S. Aldrin.
Date:November 2014
Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7394
LSP-Ping is a widely deployed Operation, Administration, andMaintenance (OAM) mechanism in MPLS networks. However, in the present form, this mechanism is inadequate to verify connectivity of a segment of a Multi-Segment Pseudowire (MS-PW) and/or bidirectional co-routed Label Switched Path (LSP) from any node on the path of theMS-PW and/or bidirectional co-routed LSP. This document defines aTLV to address this shortcoming.

RFC 7399 Unanswered Questions in the Path Computation Element Architecture
 
Authors:A. Farrel, D. King.
Date:October 2014
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 7399
The Path Computation Element (PCE) architecture is set out in RFC4655. The architecture is extended for multi-layer networking with the introduction of the Virtual Network Topology Manager (VNTM) inRFC 5623 and generalized to Hierarchical PCE (H-PCE) in RFC 6805.

These three architectural views of PCE deliberately leave some key questions unanswered, especially with respect to the interactions between architectural components. This document draws out those questions and discusses them in an architectural context with reference to other architectural components, existing protocols, and recent IETF efforts.

This document does not update the architecture documents and does not define how protocols or components must be used. It does, however, suggest how the architectural components might be combined to provide advanced PCE function.
