RFC 6701 Sanctions Available for Application to Violators of IETF IPR Policy
 
Authors:A. Farrel, P. Resnick.
Date:August 2012
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 6701
The IETF has developed and documented policies that govern the behavior of all IETF participants with respect to IntellectualProperty Rights (IPR) about which they might reasonably be aware.

The IETF takes conformance to these IPR policies very seriously.However, there has been some ambiguity as to what the appropriate sanctions are for the violation of these policies, and how and by whom those sanctions are to be applied.

This document discusses these issues and provides a suite of potential actions that can be taken within the IETF community in cases related to patents.

 
RFC 6702 Promoting Compliance with Intellectual Property Rights (IPR) Disclosure Rules
 
Authors:T. Polk, P. Saint-Andre.
Date:August 2012
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 6702
The disclosure process for intellectual property rights (IPR) in documents produced within the IETF stream is essential to the accurate development of community consensus. However, this process is not always followed by IETF participants. Regardless of the cause or motivation, noncompliance with IPR disclosure rules can delay or even derail completion of IETF specifications. This document describes some strategies for promoting compliance with the IPR disclosure rules. These strategies are primarily intended for use by area directors, working group chairs, and working group secretaries.
 
RFC 6703 Reporting IP Network Performance Metrics: Different Points of View
 
Authors:A. Morton, G. Ramachandran, G. Maguluri.
Date:August 2012
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 6703
Consumers of IP network performance metrics have many different uses in mind. This memo provides "long-term" reporting considerations(e.g., hours, days, weeks, or months, as opposed to 10 seconds), based on analysis of the points of view of two key audiences. It describes how these audience categories affect the selection of metric parameters and options when seeking information that serves their needs.
 
RFC 6704 Forcerenew Nonce Authentication
 
Authors:D. Miles, W. Dec, J. Bristow, R. Maglione.
Date:August 2012
Formats:txt pdf
Updates:RFC 3203
Status:PROPOSED STANDARD
DOI:10.17487/RFC 6704
Dynamic Host Configuration Protocol (DHCP) FORCERENEW allows for the reconfiguration of a single host by forcing the DHCP client into aRenew state on a trigger from the DHCP server. In the ForcerenewNonce Authentication protocol, the server sends a nonce to the client in the initial DHCP ACK that is used for subsequent validation of aFORCERENEW message. This document updates RFC 3203.
 
RFC 6705 Localized Routing for Proxy Mobile IPv6
 
Authors:S. Krishnan, R. Koodli, P. Loureiro, Q. Wu, A. Dutta.
Date:September 2012
Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 6705
Proxy Mobile IPv6 (PMIPv6) is a network based mobility management protocol that enables IP mobility for a host without requiring its participation in any mobility-related signaling. PMIPv6 requires all communications to go through the local mobility anchor. As this can be suboptimal, Localized Routing (LR) allows Mobile Nodes (MNs) attached to the same or different Mobile Access Gateways (MAGs) to route traffic by using localized forwarding or a direct tunnel between the gateways. This document proposes initiation, utilization, and termination mechanisms for localized routing between mobile access gateways within a proxy mobile IPv6 domain. It defines two new signaling messages, Localized Routing Initiation (LRI) andLocal Routing Acknowledgment (LRA), that are used to realize this mechanism.
 
RFC 6706 Asymmetric Extended Route Optimization (AERO)
 
Authors:F. Templin, Ed..
Date:August 2012
Formats:txt pdf
Status:EXPERIMENTAL
DOI:10.17487/RFC 6706
Nodes attached to common multi-access link types (e.g., multicast- capable, shared media, non-broadcast multiple access (NBMA), etc.) can exchange packets as neighbors on the link, but they may not always be provisioned with sufficient routing information for optimal neighbor selection. Such nodes should therefore be able to discover a trusted intermediate router on the link that provides both forwarding services to reach off-link destinations and redirection services to inform the node of an on-link neighbor that is closer to the final destination. This redirection can provide a useful route optimization, since the triangular path from the ingress link neighbor, to the intermediate router, and finally to the egress link neighbor may be considerably longer than the direct path from ingress to egress. However, ordinary redirection may lead to operational issues on certain link types and/or in certain deployment scenarios.This document therefore introduces an Asymmetric Extended RouteOptimization (AERO) capability that addresses the issues.
 
RFC 6707 Content Distribution Network Interconnection (CDNI) Problem Statement
 
Authors:B. Niven-Jenkins, F. Le Faucheur, N. Bitar.
Date:September 2012
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 6707
Content Delivery Networks (CDNs) provide numerous benefits for cacheable content: reduced delivery cost, improved quality of experience for End Users, and increased robustness of delivery. For these reasons, they are frequently used for large-scale content delivery. As a result, existing CDN Providers are scaling up their infrastructure, and many Network Service Providers (NSPs) are deploying their own CDNs. It is generally desirable that a given content item can be delivered to an End User regardless of that EndUser's location or attachment network. This is the motivation for interconnecting standalone CDNs so they can interoperate as an open content delivery infrastructure for the end-to-end delivery of content from Content Service Providers (CSPs) to End Users. However, no standards or open specifications currently exist to facilitate such CDN Interconnection.

The goal of this document is to outline the problem area of CDNInterconnection for the IETF CDNI (CDN Interconnection) working group.

 
RFC 6708 Application-Layer Traffic Optimization (ALTO) Requirements
 
Authors:S. Kiesel, Ed., S. Previdi, M. Stiemerling, R. Woundy, Y. Yang.
Date:September 2012
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 6708
Many Internet applications are used to access resources, such as pieces of information or server processes that are available in several equivalent replicas on different hosts. This includes, but is not limited to, peer-to-peer file sharing applications. 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.This guidance shall be based on parameters that affect performance and efficiency of the data transmission between the hosts, e.g., the topological distance. The ultimate goal is to improve performance orQuality of Experience in the application while reducing the utilization of the underlying network infrastructure.

This document enumerates requirements for specifying, assessing, or comparing protocols and implementations.

Authors:C. Holmberg, S. Blau, E. Burger.
Date:August 2012
Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 6714
This document defines a Message Session Relay Protocol (MSRP) extension, Connection Establishment for Media Anchoring (CEMA).Support of this extension is OPTIONAL. The extension allows middleboxes to anchor the MSRP connection, without the need for middleboxes to modify the MSRP messages; thus, it also enables secure end-to-end MSRP communication in networks where such middleboxes are deployed. This document also defines a Session Description Protocol(SDP) attribute, 'msrp-cema', that MSRP endpoints use to indicate support of the CEMA extension.

RFC 6717 kx509 Kerberized Certificate Issuance Protocol in Use in 2012
 
Authors:H. Hotz, R. Allbery.
Date:August 2012
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 6717
This document describes a protocol, called kx509, for using Kerberos tickets to acquire X.509 certificates. These certificates may be used for many of the same purposes as X.509 certificates acquired by other means, but if a Kerberos infrastructure already exists, then the overhead of using kx509 may be much less.

While not standardized, this protocol is already in use at several large organizations, and certificates issued with this protocol are recognized by the International Grid Trust Federation.

 
RFC 6718 Pseudowire Redundancy

Date:August 2012
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 6718
This document describes a framework comprised of a number of scenarios and associated requirements for pseudowire (PW) redundancy.A set of redundant PWs is configured between provider edge (PE) nodes in single-segment PW applications or between terminating PE (T-PE) nodes in multi-segment PW applications. In order for the PE/T-PE nodes to indicate the preferred PW to use for forwarding PW packets to one another, a new PW status is required to indicate the preferential forwarding status of active or standby for each PW in the redundant set.
 
RFC 6719 The Minimum Rank with Hysteresis Objective Function
 
Authors:O. Gnawali, P. Levis.
Date:September 2012
Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 6719
The Routing Protocol for Low-Power and Lossy Networks (RPL) constructs routes by using Objective Functions that optimize or constrain the routes it selects and uses. This specification describes the Minimum Rank with Hysteresis Objective Function(MRHOF), an Objective Function that selects routes that minimize a metric, while using hysteresis to reduce churn in response to small metric changes. MRHOF works with additive metrics along a route, and the metrics it uses are determined by the metrics that the RPLDestination Information Object (DIO) messages advertise.
 
RFC 6720 The Generalized TTL Security Mechanism (GTSM) for the Label Distribution Protocol (LDP)
 
Authors:C. Pignataro, R. Asati.
Date:August 2012
Formats:txt pdf
Updates:RFC 5036
Updated by:RFC 7552
Status:PROPOSED STANDARD
DOI:10.17487/RFC 6720
The Generalized TTL Security Mechanism (GTSM) describes a generalized use of a packet's Time to Live (TTL) (IPv4) or Hop Limit (IPv6) to verify that the packet was sourced by a node on a connected link, thereby protecting the router's IP control plane from CPU utilization-based attacks. This technique improves security and is used by many protocols. This document defines the GTSM use for theLabel Distribution Protocol (LDP).

This specification uses a bit reserved in RFC 5036 and therefore updates RFC 5036.

This document updates RFC 4447 and RFC 6073 by adding the Label Request message to resolve this control-word negotiation issue for single-segment and multi-segment pseudowires.
 
RFC 6724 Default Address Selection for Internet Protocol Version 6 (IPv6)
 
Authors:D. Thaler, Ed., R. Draves, A. Matsumoto, T. Chown.
Date:September 2012
Formats:txt pdf
Obsoletes:RFC 3484
Status:PROPOSED STANDARD
DOI:10.17487/RFC 6724
This document describes two algorithms, one for source address selection and one for destination address selection. The algorithms specify default behavior for all Internet Protocol version 6 (IPv6) implementations. They do not override choices made by applications or upper-layer protocols, nor do they preclude the development of more advanced mechanisms for address selection. The two algorithms share a common context, including an optional mechanism for allowing administrators to provide policy that can override the default behavior. In dual-stack implementations, the destination address selection algorithm can consider both IPv4 and IPv6 addresses -- depending on the available source addresses, the algorithm might prefer IPv6 addresses over IPv4 addresses, or vice versa.

Default address selection as defined in this specification applies to all IPv6 nodes, including both hosts and routers. This document obsoletes RFC 3484.

RFC 6731 Improved Recursive DNS Server Selection for Multi-Interfaced Nodes
 
Authors:T. Savolainen, J. Kato, T. Lemon.
Date:December 2012
Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 6731
A multi-interfaced node is connected to multiple networks, some of which might be utilizing private DNS namespaces. A node commonly receives recursive DNS server configuration information from all connected networks. Some of the recursive DNS servers might have information about namespaces other servers do not have. When a multi-interfaced node needs to utilize DNS, the node has to choose which of the recursive DNS servers to use. This document describesDHCPv4 and DHCPv6 options that can be used to configure nodes with information required to perform informed recursive DNS server selection decisions.
 
RFC 6732 6to4 Provider Managed Tunnels
 
Authors:V. Kuarsingh, Ed., Y. Lee, O. Vautrin.
Date:September 2012
Formats:txt pdf
Obsoleted by:RFC 7526
Status:HISTORIC
DOI:10.17487/RFC 6732
6to4 Provider Managed Tunnels (6to4-PMT) provide a framework that can help manage 6to4 tunnels operating in an anycast configuration. The6to4-PMT framework is intended to serve as an option for operators to help improve the experience of 6to4 operation when conditions of the network may provide sub-optimal performance or break normal 6to4 operation. 6to4-PMT supplies a stable provider prefix and forwarding environment by utilizing existing 6to4 relays with an added function of IPv6 Prefix Translation. This operation may be particularly important in NAT444 infrastructures where a customer endpoint may be assigned a non-RFC1918 address, thus breaking the return path for anycast-based 6to4 operation. 6to4-PMT has been successfully used in a production network, implemented as open source code, and implemented by a major routing vendor.

RFC 6736 Diameter Network Address and Port Translation Control Application
 
Authors:F. Brockners, S. Bhandari, V. Singh, V. Fajardo.
Date:October 2012
Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 6736
This document describes the framework, messages, and procedures for the Diameter Network address and port translation ControlApplication. This Diameter application allows per-endpoint control of Network Address Translators and Network Address and PortTranslators, which are added to networks to cope with IPv4 address space depletion. This Diameter application allows external devices to configure and manage a Network Address Translator device -- expanding the existing Diameter-based Authentication, Authorization, and Accounting (AAA) and policy control capabilities with a NetworkAddress Translator and Network Address and Port Translator control component. These external devices can be network elements in the data plane such as a Network Access Server, or can be more centralized control plane devices such as AAA-servers. This Diameter application establishes a context to commonly identify and manage endpoints on a gateway or server and a Network Address Translator andNetwork Address and Port Translator device. This includes, for example, the control of the total number of Network AddressTranslator bindings allowed or the allocation of a specific NetworkAddress Translator binding for a particular endpoint. In addition, it allows Network Address Translator devices to provide information relevant to accounting purposes.

RFC 6738 Diameter IKEv2 SK: Using Shared Keys to Support Interaction between IKEv2 Servers and Diameter Servers
 
Authors:V. Cakulev, A. Lior, S. Mizikovsky.
Date:October 2012
Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 6738
The Internet Key Exchange Protocol version 2 (IKEv2) is a component of the IPsec architecture and is used to perform mutual authentication as well as to establish and to maintain IPsec SecurityAssociations (SAs) between the respective parties. IKEv2 supports several different authentication mechanisms, such as the ExtensibleAuthentication Protocol (EAP), certificates, and Shared Key (SK).

Diameter interworking for Mobile IPv6 between the Home Agent (HA), as a Diameter client, and the Diameter server has been specified.However, that specification focused on the usage of EAP and did not include support for SK-based authentication available with IKEv2.This document specifies the IKEv2-server-to-Diameter-server communication when the IKEv2 peer authenticates using IKEv2 with SK.

 
RFC 6739 Synchronizing Service Boundaries and Elements Based on the Location-to-Service Translation (LoST) Protocol
 
Authors:H. Schulzrinne, H. Tschofenig.
Date:October 2012
Formats:txt pdf
Status:EXPERIMENTAL
DOI:10.17487/RFC 6739
The Location-to-Service Translation (LoST) protocol is an XML-based protocol for mapping service identifiers and geodetic or civic location information to service URIs and service boundaries. In particular, it can be used to determine the location-appropriatePublic Safety Answering Point (PSAP) for emergency services.

The <mapping&rt; element in the LoST protocol specification encapsulates information about service boundaries and circumscribes the region within which all locations map to the same service Uniform ResourceIdentifier (URI) or set of URIs for a given service.

This document defines an XML protocol to exchange these mappings between two nodes. This mechanism is designed for the exchange of authoritative <mapping&rt; elements between two entities. Exchanging cached <mapping&rt; elements, i.e., non-authoritative elements, is possible but not envisioned. Even though the <mapping&rt; element format is reused from the LoST specification, the mechanism in this document can be used without the LoST protocol.

Status:EXPERIMENTAL
DOI:10.17487/RFC 6751
In customer sites having IPv4-only Customer Premises Equipment (CPE),Teredo (RFC 4380, RFC 5991, RFC 6081) provides last-resort IPv6 connectivity. However, because it is designed to work without the involvement of Internet Service Providers, it has significant limitations (connectivity between IPv6 native addresses and Teredo addresses is uncertain; connectivity between Teredo addresses fails for some combinations of NAT types). 6a44 is a complementary solution that, being based on ISP cooperation, avoids these limitations. At the beginning of 6a44 IPv6 addresses, it replaces the Teredo well-known prefix, present at the beginning of Teredo IPv6 addresses, with network-specific /48 prefixes assigned by local ISPs(an evolution similar to that from 6to4 to 6rd (IPv6 Rapid Deployment on IPv4 Infrastructures)). The specification is expected to be complete enough for running code to be independently written and the solution to be incrementally deployed and used.

RFC 6754 Protocol Independent Multicast Equal-Cost Multipath (ECMP) Redirect
 
Authors:Y. Cai, L. Wei, H. Ou, V. Arya, S. Jethwani.

Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 6754
A Protocol Independent Multicast (PIM) router uses the Reverse PathForwarding (RPF) procedure to select an upstream interface and router in order to build forwarding state. When there are equal-cost multipaths (ECMPs), existing implementations often use hash algorithms to select a path. Such algorithms do not allow the spread of traffic among the ECMPs according to administrative metrics. This usually leads to inefficient or ineffective use of network resources.This document introduces the ECMP Redirect, a mechanism to improve the RPF procedure over ECMPs. It allows ECMP selection to be based on administratively selected metrics, such as data transmission delays, path preferences, and routing metrics.

RFC 6762 Multicast DNS
 
Authors:S. Cheshire, M. Krochmal.
Date:February 2013
Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 6762
As networked devices become smaller, more portable, and more ubiquitous, the ability to operate with less configured infrastructure is increasingly important. In particular, the ability to look up DNS resource record data types (including, but not limited to, host names) in the absence of a conventional managed DNS server is useful.

Multicast DNS (mDNS) provides the ability to perform DNS-like operations on the local link in the absence of any conventionalUnicast DNS server. In addition, Multicast DNS designates a portion of the DNS namespace to be free for local use, without the need to pay any annual fee, and without the need to set up delegations or otherwise configure a conventional DNS server to answer for those names.

The primary benefits of Multicast DNS names are that (i) they require little or no administration or configuration to set them up, (ii) they work when no infrastructure is present, and (iii) they work during infrastructure failures.

Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 6769
All BGP routers in the Default-Free Zone (DFZ) are required to carry all routes in the Default-Free Routing Table (DFRT). This document describes a technique, Simple Virtual Aggregation (S-VA), that allows some BGP routers not to install all of those routes into theForwarding Information Base (FIB).

Some routers in an Autonomous System (AS) announce an aggregate (theVA prefix) in addition to the routes they already announce. This enables other routers not to install the routes covered by the VA prefix into the FIB as long as those routes have the same next-hop as the VA prefix.

The VA prefixes that are announced within an AS are not announced to any other AS. The described functionality is of very low operational complexity, as it proposes a confined BGP speaker solution without any dependency on network-wide configuration or requirement for any form of intra-domain tunneling.

RFC 6771 Considerations for Having a Successful "Bar BOF" Side Meeting
 
Authors:L. Eggert, G. Camarillo.
Date:October 2012
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 6771
New work is typically brought to the IETF by a group of interested individuals. IETF meetings are a convenient place for such groups to hold informal get-togethers to discuss and develop their ideas. Such side meetings, which are not reflected in the IETF meeting agenda and have no official status, are often half-jokingly referred to as "barBOF" sessions to acknowledge that some of them may eventually lead to a proposal for an official IETF BOF ("birds of a feather" session) on a given topic.

During recent IETF meetings, many such "bar BOF" get-togethers have been organized and moderated in ways that made them increasingly indistinguishable from official IETF BOFs or sometimes even IETF working group meetings.

This document argues that this recent trend is not helpful in reaching the ultimate goal of many of these get-togethers, i.e., to efficiently discuss and develop ideas for new IETF work. It encourages the organizers to consider the benefits of holding them in much less formal settings and to also consider alternative means to develop their ideas. This document also recommends that the community abandon the term "bar BOF" and instead use other terms such as "side meeting", in order to stress the unofficial nature of these get-togethers.

DOI:10.17487/RFC 6772
This document defines an authorization policy language for controlling access to location information. It extends the CommonPolicy authorization framework to provide location-specific access control. More specifically, this document defines condition elements specific to location information in order to restrict access to data based on the current location of the Target.

Furthermore, this document defines two algorithms for reducing the granularity of returned location information. The first algorithm is defined for usage with civic location information, whereas the other one applies to geodetic location information. Both algorithms come with limitations. There are circumstances where the amount of location obfuscation provided is less than what is desired. These algorithms might not be appropriate for all application domains.

RFC 6774 Distribution of Diverse BGP Paths
 
Authors:R. Raszuk, Ed., R. Fernando, K. Patel, D. McPherson, K. Kumaki.
Date:November 2012
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 6774
The BGP4 protocol specifies the selection and propagation of a single best path for each prefix. As defined and widely deployed today, BGP has no mechanisms to distribute alternate paths that are not considered best path between its speakers. This behavior results in a number of disadvantages for new applications and services.

The main objective of this document is to observe that by simply adding a new session between a route reflector and its client, theNth best path can be distributed. This document also compares existing solutions and proposed ideas that enable distribution of more paths than just the best path.

This proposal does not specify any changes to the BGP protocol definition. It does not require a software upgrade of provider edge(PE) routers acting as route reflector clients.

 
RFC 6775 Neighbor Discovery Optimization for IPv6 over Low-Power Wireless Personal Area Networks (6LoWPANs)

Date:November 2012
Formats:txt pdf
Updates:RFC 4944
Status:PROPOSED STANDARD
DOI:10.17487/RFC 6775
The IETF work in IPv6 over Low-power Wireless Personal Area Network(6LoWPAN) defines 6LoWPANs such as IEEE 802.15.4. This and other similar link technologies have limited or no usage of multicast signaling due to energy conservation. In addition, the wireless network may not strictly follow the traditional concept of IP subnets and IP links. IPv6 Neighbor Discovery was not designed for non- transitive wireless links, as its reliance on the traditional IPv6 link concept and its heavy use of multicast make it inefficient and sometimes impractical in a low-power and lossy network. This document describes simple optimizations to IPv6 Neighbor Discovery, its addressing mechanisms, and duplicate address detection for Low- power Wireless Personal Area Networks and similar networks. The document thus updates RFC 4944 to specify the use of the optimizations defined here.

Status:PROPOSED STANDARD
DOI:10.17487/RFC 6777
When setting up a Label Switched Path (LSP) in Generalized MPLS(GMPLS) and MPLS Traffic Engineering (MPLS-TE) networks, the completion of the signaling process does not necessarily mean that the cross-connection along the LSP has been programmed accordingly and in a timely manner. Meanwhile, the completion of the signaling process may be used by LSP users or applications that control their use as an indication that the data path has become usable. The existence of the inconsistency between the signaling messages and cross-connection programming, and the possible failure of cross- connection programming, if not properly treated, will result in data loss or even application failure. Characterization of this performance can thus help designers to improve the way in which LSPs are used and to make applications or tools that depend on and useLSPs more robust. This document defines a series of performance metrics to evaluate the connectivity of the data path in the signaling process.

Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 6782
Operators worldwide are in various stages of preparing for or deploying IPv6 in their networks. These operators often face difficult challenges related to IPv6 introduction, along with those related to IPv4 run-out. Operators will need to meet the simultaneous needs of IPv6 connectivity and continue support for IPv4 connectivity for legacy devices with a stagnant supply of IPv4 addresses. The IPv6 transition will take most networks from an IPv4- only environment to an IPv6-dominant environment with long transition periods varying by operator. This document helps provide a framework for wireline providers who are faced with the challenges of introducing IPv6 along with meeting the legacy needs of IPv4 connectivity, utilizing well-defined and commercially available IPv6 transition technologies.

RFC 6787 Media Resource Control Protocol Version 2 (MRCPv2)
 
Authors:D. Burnett, S. Shanmugham.
Date:November 2012
Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 6787
The Media Resource Control Protocol Version 2 (MRCPv2) allows client hosts to control media service resources such as speech synthesizers, recognizers, verifiers, and identifiers residing in servers on the network. MRCPv2 is not a "stand-alone" protocol -- it relies on other protocols, such as the Session Initiation Protocol (SIP), to coordinate MRCPv2 clients and servers and manage sessions between them, and the Session Description Protocol (SDP) to describe, discover, and exchange capabilities. It also depends on SIP and SDP to establish the media sessions and associated parameters between the media source or sink and the media server. Once this is done, theMRCPv2 exchange operates over the control session established above, allowing the client to control the media processing resources on the speech resource server.
 
RFC 6788 The Line-Identification Option

In Ethernet-based aggregation networks, several subscriber premises may be logically connected to the same interface of an Edge Router.This document proposes a method for the Edge Router to identify the subscriber premises using the contents of the received RouterSolicitation messages. The applicability is limited to broadband network deployment scenarios in which multiple user ports are mapped to the same virtual interface on the Edge Router.
 
RFC 6789 Congestion Exposure (ConEx) Concepts and Use Cases
 
Authors:B. Briscoe, Ed., R. Woundy, Ed., A. Cooper, Ed..
Date:December 2012
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 6789
This document provides the entry point to the set of documentation about the Congestion Exposure (ConEx) protocol. It explains the motivation for including a ConEx marking at the IP layer: to expose information about congestion to network nodes. Although such information may have a number of uses, this document focuses on how the information communicated by the ConEx marking can serve as the basis for significantly more efficient and effective traffic management than what exists on the Internet today.
 
RFC 6790 The Use of Entropy Labels in MPLS Forwarding

Load balancing is a powerful tool for engineering traffic across a network. This memo suggests ways of improving load balancing acrossMPLS networks using the concept of "entropy labels". It defines the concept, describes why entropy labels are useful, enumerates properties of entropy labels that allow maximal benefit, and shows how they can be signaled and used for various applications. This document updates RFCs 3031, 3107, 3209, and 5036.
 
RFC 6791 Stateless Source Address Mapping for ICMPv6 Packets
 
Authors:X. Li, C. Bao, D. Wing, R. Vaithianathan, G. Huston.

Updates:RFC 6145
Status:PROPOSED STANDARD
DOI:10.17487/RFC 6791
A stateless IPv4/IPv6 translator may receive ICMPv6 packets containing non-IPv4-translatable addresses as the source. These packets should be passed across the translator as ICMP packets directed to the IPv4 destination. This document presents recommendations for source address translation in ICMPv6 headers to handle such cases.
 
RFC 6792 Guidelines for Use of the RTP Monitoring Framework
 
Authors:Q. Wu, Ed., G. Hunt, P. Arden.
Date:November 2012
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 6792
This memo proposes an extensible Real-time Transport Protocol (RTP) monitoring framework for extending the RTP Control Protocol (RTCP) with a new RTCP Extended Reports (XR) block type to report new metrics regarding media transmission or reception quality. In this framework, a new XR block should contain a single metric or a small number of metrics relevant to a single parameter of interest or concern, rather than containing a number of metrics that attempt to provide full coverage of all those parameters of concern to a specific application. Applications may then "mix and match" to create a set of blocks that cover their set of concerns. Where possible, a specific block should be designed to be reusable across more than one application, for example, for all of voice, streaming audio, and video.
