Rough Guide to IETF 90: Scalability & Performance

Mat Ford
Mat FordTechnology Program Manager

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 90 meeting in Toronto next week.
I’ll highlight one birds-of-a-feather (BoF) meeting: The Delay Tolerant Networking (DTN) BoF is looking to investigate interest in transitioning technologies developed in the IRTF DTN research group into standards-track activities through the formation of a new IETF working group. Examples of the sort of environments where DTN solutions may be appropriate include spacecraft, military/tactical, some forms of disaster response, underwater, and some forms of ad-hoc sensor/actuator networks. They may also include Internet connectivity in places where performance may suffer such as developing parts of the world.
After their BoF meeting at IETF 89 in London, the Transport Services (TAPS) Working Group has been formed and will have its first meeting in Toronto. The group is wrestling with the problem of how to provide a richer set of transport services to applications without many of the complications that exist today resulting in developers either using TCP or implementing their own customized solution over UDP.
The TCPcrypt ‘mini-BoF’ meeting in London has also yielded a new working group and the TCP Increased Security (tcpinc) Working Group will have its first face-to-face meeting to begin work to develop the TCP extensions to provide unauthenticated encryption and integrity protection of TCP streams.
In the IRTF, a proposed research group on the subject of data centre latency control (dclcrg) will meet. 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 will seek to develop shared problem statements, solutions and other experimental tools.
