Deliverable D2.7 - 6QM and IETF activities

This document examines the various working groups in the IETF that are relevant to the 6QM project. In particular, a general description of each working group is given, plus the goals and milestones, and the drafts and request for comments that are associated with each group.

The following groups have been included:
- IP Version 6 (ipv6): Provides a home for IPv6 work that spans multiple working groups.
- IP Version 6 Operations (v6ops): Develops guidelines for the operation of a shared IPv4/IPv6 Internet and provides guidance for network operators on how to deploy IPv6 into existing IPv4-only networks, as well as into new network installations.
- Benchmarking Methodology (bmwg): Focus is to make a series of recommendations concerning the measurement of the performance characteristics of various internetworking technologies.
- IP Performance Metrics (ippm): Develop a set of standard metrics that can be applied to the quality, performance, and reliability of Internet data delivery services.
- IP Flow Information Export (ipfix): Define a standard set of capabilities by which IP flow information can be transferred.
- Packet sampling (psamp): Define a standard set of capabilities to sample subsets of packets.
- Remote Network Monitoring (rmon): Chartered to define a set of managed objects for remote monitoring of networks.
- Internet Traffic Engineering (tewg): Traffic Engineering entails that aspect of network engineering which is concerned with the design, provisioning, and tuning of operational internet networks.
- Audio and Video Transport (avt): The Audio/Video Transport Working Group was formed to specify a protocol for real-time transmission of audio and video over UDP and IP multicast.
- Inter-domain routing (idr): The objective is to promote the use of BGP-4 to support IP version 4 and IP version 6.

The working group will continue to work on improving the scalability of BGP. Various standardized measurement architectures are described and then compared. These include, but are not limited to:
- RMON: Remote Monitoring is a standard monitoring specification that enables various network monitors and console systems to exchange network-monitoring data.
- IPPM: defines a MIB for managing the measures using the IP performance metrics specified by the IPPM Working Group.
- RTFM: The RTFM architecture is an attempt by IETF to standardize several aspects of flow definition, capture and metering operations [RFC2722].
- Sflow: a technology for monitoring traffic in data networks containing switches and routers.
- IPFIX: Currently defining an architecture that employs the concept of collector, observation point, and metering process.
