In this post I’ll shine a light on some of the Internet Engineering Task Force (IETF) and Internet Research Task Force (IRTF) efforts underway to explore and address more sophisticated ways to use available bandwidth, improve Internet performance, and otherwise efficiently get content to where it needs to be. These groups will all be meeting as part of the IETF 91 meeting in Honolulu next week.
The Deterministic Networking (detnet) BoF will explore the feasibility of extending IEEE Audio Video Bridging to routed networks. The IEEE standard provides time synchronization and precise scheduling for zero congestion loss and finite latency for reserved layer-2 streams. The need to extend these QoS features to routed networks is now emerging for industrial and vehicular applications. The detnet problem statement contains more detail about the motivations for this work.
Internet performance is to a large extent governed by the way transport protocols operate, and the tcpm WG will be meeting to discuss proposed new functionality to improve and enhance the working of TCP, the main transport protocol used on the Internet today.
Packet networks give rise to transient congestion by design and several groups are meeting to discuss different aspects of congestion control and avoidance (aqm, iccrg and rmcat). For regulators, being able to monitor the performance of networks, and the extent to which congestion or other factors are impacting consumers’ experience of the network is very important. The lmap working group is meeting in Honolulu to advance their important work on standardizing a large-scale broadband performance measurement infrastructure.
Reducing Internet latency is important to us at the Internet Society and in the IRTF, the proposed research group on the subject of data centre latency control (dclcrg) will meet again at IETF 91. In recent years a number of techniques have been documented in the research literature on reducing latency for applications running in large data centres and this research group seeks to develop shared problem statements, solutions and other experimental tools.
