RFC 7200 A Session Initiation Protocol (SIP) Load-Control Event Package
 
Authors:C. Shen, H. Schulzrinne, A. Koike.
Date:April 2014
Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7200
This specification defines a load-control event package for theSession Initiation Protocol (SIP). It allows SIP entities to distribute load-filtering policies to other SIP entities in the network. The load-filtering policies contain rules to throttle calls from a specific user or based on their source or destination domain, telephone number prefix. The mechanism helps to prevent signaling overload and complements feedback-based SIP overload control efforts.
 
RFC 7201 Options for Securing RTP Sessions
 
Authors:M. Westerlund, C. Perkins.
Date:April 2014
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 7201
The Real-time Transport Protocol (RTP) is used in a large number of different application domains and environments. This heterogeneity implies that different security mechanisms are needed to provide services such as confidentiality, integrity, and source authentication of RTP and RTP Control Protocol (RTCP) packets suitable for the various environments. The range of solutions makes it difficult for RTP-based application developers to pick the most suitable mechanism. This document provides an overview of a number of security solutions for RTP and gives guidance for developers on how to choose the appropriate security mechanism.
 
RFC 7202 Securing the RTP Framework: Why RTP Does Not Mandate a Single Media Security Solution
 
Authors:C. Perkins, M. Westerlund.
Date:April 2014
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 7202
This memo discusses the problem of securing real-time multimedia sessions. It also explains why the Real-time Transport Protocol(RTP) and the associated RTP Control Protocol (RTCP) do not mandate a single media security mechanism. This is relevant for designers and reviewers of future RTP extensions to ensure that appropriate security mechanisms are mandated and that any such mechanisms are specified in a manner that conforms with the RTP architecture.

RFC 7205 Use Cases for Telepresence Multistreams
 
Authors:A. Romanow, S. Botzko, M. Duckworth, R. Even, Ed..
Date:April 2014
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 7205
Telepresence conferencing systems seek to create an environment that gives users (or user groups) that are not co-located a feeling of co- located presence through multimedia communication that includes at least audio and video signals of high fidelity. A number of techniques for handling audio and video streams are used to create this experience. When these techniques are not similar, interoperability between different systems is difficult at best, and often not possible. Conveying information about the relationships between multiple streams of media would enable senders and receivers to make choices to allow telepresence systems to interwork. This memo describes the most typical and important use cases for sending multiple streams in a telepresence conference.

Date:April 2014
Formats:txt pdf
Obsoletes:RFC 4408
Updated by:RFC 7372
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7208
Email on the Internet can be forged in a number of ways. In particular, existing protocols place no restriction on what a sending host can use as the "MAIL FROM" of a message or the domain given on the SMTP HELO/EHLO commands. This document describes version 1 of the Sender Policy Framework (SPF) protocol, whereby ADministrativeManagement Domains (ADMDs) can explicitly authorize the hosts that are allowed to use their domain names, and a receiving host can check such authorization.

This document obsoletes RFC 4408.

 
RFC 7209 Requirements for Ethernet VPN (EVPN)
 
Authors:A. Sajassi, R. Aggarwal, J. Uttaro, N. Bitar, W. Henderickx, A. Isaac.
Date:May 2014
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 7209
The widespread adoption of Ethernet L2VPN services and the advent of new applications for the technology (e.g., data center interconnect) have culminated in a new set of requirements that are not readily addressable by the current Virtual Private LAN Service (VPLS) solution. In particular, multihoming with all-active forwarding is not supported, and there's no existing solution to leverageMultipoint-to-Multipoint (MP2MP) Label Switched Paths (LSPs) for optimizing the delivery of multi-destination frames. Furthermore, the provisioning of VPLS, even in the context of BGP-based auto- discovery, requires network operators to specify various network parameters on top of the access configuration. This document specifies the requirements for an Ethernet VPN (EVPN) solution, which addresses the above issues.
 
RFC 7210 Database of Long-Lived Symmetric Cryptographic Keys
 
Authors:R. Housley, T. Polk, S. Hartman, D. Zhang.
Date:April 2014
Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7210
This document specifies the information contained in a conceptual database of long-lived cryptographic keys used by many different routing protocols for message security. The database is designed to support both manual and automated key management. In addition to describing the schema for the database, this document describes the operations that can be performed on the database as well as the requirements for the routing protocols that wish to use the database.In many typical scenarios, the protocols do not directly use the long-lived key, but rather a key derivation function is used to derive a short-lived key from a long-lived key.
 
RFC 7211 Operations Model for Router Keying
 
Authors:S. Hartman, D. Zhang.
Date:June 2014
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 7211
The IETF is engaged in an effort to analyze the security of routing protocol authentication according to design guidelines discussed inRFC 6518, "Keying and Authentication for Routing Protocols (KARP)Design Guidelines". Developing an operational and management model for routing protocol security that works with all the routing protocols will be critical to the deployability of these efforts.This document gives recommendations to operators and implementors regarding management and operation of router authentication. These recommendations will also assist protocol designers in understanding management issues they will face.
 
RFC 7212 MPLS Generic Associated Channel (G-ACh) Advertisement Protocol
 
Authors:D. Frost, S. Bryant, M. Bocci.
Date:June 2014
Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7212
The MPLS Generic Associated Channel (G-ACh) provides an auxiliary logical data channel associated with a Label Switched Path (LSP), a pseudowire, or a section (link) over which a variety of protocols may flow. These protocols are commonly used to provide Operations,Administration, and Maintenance (OAM) mechanisms associated with the primary data channel. This document specifies simple procedures by which an endpoint of an LSP, pseudowire, or section may inform the other endpoints of its capabilities and configuration parameters, or other application-specific information. This information may then be used by the receiver to validate or adjust its local configuration, and by the network operator for diagnostic purposes.

RFC 7216 Location Information Server (LIS) Discovery Using IP Addresses and Reverse DNS
 
Authors:M. Thomson, R. Bellis.
Date:April 2014
Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7216
The residential gateway is a device that has become an integral part of home networking equipment. Discovering a Location InformationServer (LIS) is a necessary part of acquiring location information for location-based services. However, discovering a LIS when a residential gateway is present poses a configuration challenge, requiring a method that is able to work around the obstacle presented by the gateway.

This document describes a solution to this problem. The solution provides alternative domain names as input to the LIS discovery process based on the network addresses assigned to a Device.

 
RFC 7217 A Method for Generating Semantically Opaque Interface Identifiers with IPv6 Stateless Address Autoconfiguration (SLAAC)
 
Authors:F. Gont.
Date:April 2014
Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7217
This document specifies a method for generating IPv6 InterfaceIdentifiers to be used with IPv6 Stateless Address Autoconfiguration(SLAAC), such that an IPv6 address configured using this method is stable within each subnet, but the corresponding Interface Identifier changes when the host moves from one network to another. This method is meant to be an alternative to generating Interface Identifiers based on hardware addresses (e.g., IEEE LAN Media Access Control(MAC) addresses), such that the benefits of stable addresses can be achieved without sacrificing the security and privacy of users. The method specified in this document applies to all prefixes a host may be employing, including link-local, global, and unique-local prefixes(and their corresponding addresses).

RFC 7221 Handling of Internet-Drafts by IETF Working Groups
 
Authors:A. Farrel, D. Crocker, Ed..
Date:April 2014
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 7221
The productive output of an IETF working group is documents, as mandated by the working group's charter. When a working group is ready to develop a particular document, the most common mechanism is for it to "adopt" an existing document as a starting point. The document that a working group adopts and then develops further is based on initial input at varying levels of maturity. An initial working group draft might be a document already in wide use, or it might be a blank sheet, wholly created by the working group, or it might represent any level of maturity in between. This document discusses how a working group typically handles the formal documents that it targets for publication.
 
RFC 7222 Quality-of-Service Option for Proxy Mobile IPv6
 
Authors:M. Liebsch, P. Seite, H. Yokota, J. Korhonen, S. Gundavelli.
Date:May 2014
Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7222
This specification defines a new mobility option, the Quality-of-Service (QoS) option, for Proxy Mobile IPv6. This option can be used by the local mobility anchor and the mobile access gateway for negotiating Quality-of-Service parameters for a mobile node's IP flows. The negotiated QoS parameters can be used for QoS policing and marking of packets to enforce QoS differentiation on the path between the local mobility anchor and the mobile access gateway.Furthermore, making QoS parameters available on the mobile access gateway enables mapping of these parameters to QoS rules that are specific to the access technology and allows those rules to be enforced on the access network using access-technology-specific approaches.

RFC 7246 Multipoint Label Distribution Protocol In-Band Signaling in a Virtual Routing and Forwarding (VRF) Table Context
 
Authors:IJ. Wijnands, Ed., P. Hitchen, N. Leymann, W. Henderickx, A. Gulko, J. Tantsura.
Date:June 2014
Formats:txt pdf
Updated by:RFC 7438
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7246
An IP Multicast Distribution Tree (MDT) may traverse both label switching (i.e., Multiprotocol Label Switching, or MPLS) and non- label switching regions of a network. Typically, the MDT begins and ends in non-MPLS regions, but travels through an MPLS region. In such cases, it can be useful to begin building the MDT as a pure IPMDT, then convert it to an MPLS Multipoint Label Switched Path(MP-LSP) when it enters an MPLS-enabled region, and then convert it back to a pure IP MDT when it enters a non-MPLS-enabled region.Other documents specify the procedures for building such a hybridMDT, using Protocol Independent Multicast (PIM) in the non-MPLS region of the network, and using Multipoint Label DistributionProtocol (mLDP) in the MPLS region. This document extends those procedures to handle the case where the link connecting the two regions is a Virtual Routing and Forwarding (VRF) table link, as defined in the "BGP IP/MPLS VPN" specification. However, this document is primarily aimed at particular use cases where VRFs are used to support multicast applications other than multicast VPN.

RFC 7252 The Constrained Application Protocol (CoAP)
 
Authors:Z. Shelby, K. Hartke, C. Bormann.
Date:June 2014
Formats:txt pdf
Updated by:RFC 7959
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7252
The Constrained Application Protocol (CoAP) is a specialized web transfer protocol for use with constrained nodes and constrained(e.g., low-power, lossy) networks. The nodes often have 8-bit microcontrollers with small amounts of ROM and RAM, while constrained networks such as IPv6 over Low-Power Wireless Personal Area Networks(6LoWPANs) often have high packet error rates and a typical throughput of 10s of kbit/s. The protocol is designed for machine- to-machine (M2M) applications such as smart energy and building automation.

CoAP provides a request/response interaction model between application endpoints, supports built-in discovery of services and resources, and includes key concepts of the Web such as URIs andInternet media types. CoAP is designed to easily interface with HTTP for integration with the Web while meeting specialized requirements such as multicast support, very low overhead, and simplicity for constrained environments.

Some MPLS labels have been allocated for specific purposes. A block of labels (0-15) has been set aside to this end; these labels are commonly called "reserved labels". They will be called "special- purpose labels" in this document.

As there are only 16 of these special-purpose labels, caution is needed in the allocation of new special-purpose labels; yet, at the same time, forward progress should be allowed when one is called for.

This memo defines new procedures for the allocation and retirement of special-purpose labels, as well as a method to extend the special- purpose label space and a description of how to handle extended special-purpose labels in the data plane. Finally, this memo renames the IANA registry for special-purpose labels to "Special-Purpose MPLSLabel Values" and creates a new registry called the "ExtendedSpecial-Purpose MPLS Label Values" registry.

This document updates a number of previous RFCs that use the term"reserved label". Specifically, this document updates RFCs 3032,3038, 3209, 3811, 4182, 4928, 5331, 5586, 5921, 5960, 6391, 6478, and6790.

Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 7282
The IETF has had a long tradition of doing its technical work through a consensus process, taking into account the different views amongIETF participants and coming to (at least rough) consensus on technical matters. In particular, the IETF is supposed not to be run by a "majority rule" philosophy. This is why we engage in rituals like "humming" instead of voting. However, more and more of our actions are now indistinguishable from voting, and quite often we are letting the majority win the day without consideration of minority concerns. This document explains some features of rough consensus, what is not rough consensus, how we have gotten away from it, how we might think about it differently, and the things we can do in order to really achieve rough consensus.

Note: This document is quite consciously being put forward asInformational. It does not propose to change any IETF processes and is therefore not a BCP. It is simply a collection of principles, hopefully around which the IETF can come to (at least rough) consensus.

DOI:10.17487/RFC 7285
Applications using the Internet already have access to some topology information of Internet Service Provider (ISP) networks. For example, views to Internet routing tables at Looking Glass servers are available and can be practically downloaded to many network application clients. What is missing is knowledge of the underlying network topologies from the point of view of ISPs. In other words, what an ISP prefers in terms of traffic optimization -- and a way to distribute it.

The Application-Layer Traffic Optimization (ALTO) services defined in this document provide network information (e.g., basic network location structure and preferences of network paths) with the goal of modifying network resource consumption patterns while maintaining or improving application performance. The basic information of ALTO is based on abstract maps of a network. These maps provide a simplified view, yet enough information about a network for applications to effectively utilize them. Additional services are built on top of the maps.

This document describes a protocol implementing the ALTO services.Although the ALTO services would primarily be provided by ISPs, other entities, such as content service providers, could also provide ALTO services. Applications that could use the ALTO services are those that have a choice to which end points to connect. Examples of such applications are peer-to-peer (P2P) and content delivery networks.

DOI:10.17487/RFC 7286
The goal of Application-Layer Traffic Optimization (ALTO) is to provide guidance to applications that have to select one or several hosts from a set of candidates capable of providing a desired resource. ALTO is realized by a client-server protocol. Before anALTO client can ask for guidance, it needs to discover one or moreALTO servers.

This document specifies a procedure for resource-consumer-initiatedALTO server discovery, which can be used if the ALTO client is embedded in the resource consumer.

DOI:10.17487/RFC 7287
Multicast communication can be enabled in Proxy Mobile IPv6 (PMIPv6) domains via the Local Mobility Anchors by deploying MulticastListener Discovery (MLD) proxy functions at Mobile Access Gateways, by using direct traffic distribution within an ISP's access network, or by selective route optimization schemes. This document describes a base solution and an experimental protocol to support mobile multicast senders in PMIPv6 domains for all three scenarios.Protocol optimizations for synchronizing PMIPv6 with PIM, as well as a peering function for MLD proxies are defined. Mobile sources always remain agnostic of multicast mobility operations.
 
RFC 7288 Reflections on Host Firewalls

Status:INFORMATIONAL
DOI:10.17487/RFC 7288
In today's Internet, the need for firewalls is generally accepted in the industry, and indeed firewalls are widely deployed in practice.Unlike traditional firewalls that protect network links, host firewalls run in end-user systems. Often the result is that software may be running and potentially consuming resources, but then communication is blocked by a host firewall. It's taken for granted that this end state is either desirable or the best that can be achieved in practice, rather than (for example) an end state where the relevant software is not running or is running in a way that would not result in unwanted communication. In this document, we explore the issues behind these assumptions and provide suggestions on improving the architecture going forward.
 
RFC 7289 Carrier-Grade NAT (CGN) Deployment with BGP/MPLS IP VPNs
 
Authors:V. Kuarsingh, Ed., J. Cianfarani.
Date:June 2014
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 7289
This document specifies a framework to integrate a Network AddressTranslation (NAT) layer into an operator's network to function as aCarrier-Grade NAT (also known as CGN or Large-Scale NAT). The CGN infrastructure will often form a NAT444 environment as the subscriber home network will likely also maintain a subscriber-side NAT function. Exhaustion of the IPv4 address pool is a major driver compelling some operators to implement CGN. Although operators may wish to deploy IPv6 to strategically overcome IPv4 exhaustion, near- term needs may not be satisfied with an IPv6 deployment alone. This document provides a practical integration model that allows the CGN platform to be integrated into the network, meeting the connectivity needs of the subscriber while being mindful of not disrupting existing services and meeting the technical challenges that CGN brings. The model included in this document utilizes BGP/MPLS IPVPNs, which allow for virtual routing separation, helping ease theCGN's impact on the network. This document does not intend to defend the merits of CGN.
 
RFC 7290 Test Plan and Results for Advancing RFC 2680 on the Standards Track
 
Authors:L. Ciavattone, R. Geib, A. Morton, M. Wieser.
Date:July 2014
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 7290
This memo provides the supporting test plan and results to advanceRFC 2680, a performance metric RFC defining one-way packet loss metrics, along the Standards Track. Observing that the metric definitions themselves should be the primary focus rather than the implementations of metrics, this memo describes the test procedures to evaluate specific metric requirement clauses to determine if the requirement has been interpreted and implemented as intended. Two completely independent implementations have been tested against the key specifications of RFC 2680.
 
RFC 7291 DHCP Options for the Port Control Protocol (PCP)
 
Authors:M. Boucadair, R. Penno, D. Wing.
Date:July 2014
Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7291
This document specifies DHCP (IPv4 and IPv6) options to configure hosts with Port Control Protocol (PCP) server IP addresses. The use of DHCPv4 or DHCPv6 depends on the PCP deployment scenarios. The set of deployment scenarios to which DHCPv4 or DHCPv6 can be applied is outside the scope of this document.
 
RFC 7292 PKCS #12: Personal Information Exchange Syntax v1.1
 
Authors:K. Moriarty, Ed., M. Nystrom, S. Parkinson, A. Rusch, M. Scott.
Date:July 2014
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 7292
PKCS #12 v1.1 describes a transfer syntax for personal identity information, including private keys, certificates, miscellaneous secrets, and extensions. Machines, applications, browsers, Internet kiosks, and so on, that support this standard will allow a user to import, export, and exercise a single set of personal identity information. This standard supports direct transfer of personal information under several privacy and integrity modes.

This document represents a republication of PKCS #12 v1.1 from RSALaboratories' Public Key Cryptography Standard (PKCS) series. By publishing this RFC, change control is transferred to the IETF.

 
RFC 7293 The Require-Recipient-Valid-Since Header Field and SMTP Service Extension
 
Authors:W. Mills, M. Kucherawy.
Date:July 2014
Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7293
This document defines an extension for the Simple Mail TransferProtocol (SMTP) called "RRVS" to provide a method for senders to indicate to receivers a point in time when the ownership of the target mailbox was known to the sender. This can be used to detect changes of mailbox ownership and thus prevent mail from being delivered to the wrong party. This document also defines a header field called "Require-Recipient-Valid-Since" that can be used to tunnel the request through servers that do not support the extension.

The intended use of these facilities is on automatically generated messages, such as account statements or password change instructions, that might contain sensitive information, though it may also be useful in other applications.

RFC 7297 IP Connectivity Provisioning Profile (CPP)
 
Authors:M. Boucadair, C. Jacquenet, N. Wang.
Date:July 2014
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 7297
This document describes the Connectivity Provisioning Profile (CPP) and proposes a CPP template to capture IP/MPLS connectivity requirements to be met within a service delivery context (e.g., Voice over IP or IP TV). The CPP defines the set of IP transfer parameters to be supported by the underlying transport network together with a reachability scope and bandwidth/capacity needs. Appropriate performance metrics, such as one-way delay or one-way delay variation, are used to characterize an IP transfer service. Both global and restricted reachability scopes can be captured in the CPP.

Such a generic CPP template is meant to (1) facilitate the automation of the service negotiation and activation procedures, thus accelerating service provisioning, (2) set (traffic) objectives ofTraffic Engineering functions and service management functions, and(3) improve service and network management systems with 'decision- making' capabilities based upon negotiated/offered CPPs.
