Applied Networking Research Prize presentations at IETF 111

    22 Jul 2021

    Presentations on research into network specification and verification and on low-latency video streaming will be featured during the Internet Research Task Force Open session of the IETF 111 Online meeting scheduled for 26-30 July.

    Applied Networking Research Prize (ANRP) awards are presented each year for recent results in applied networking research that are relevant to shipping Internet products and related standardization efforts. The ANRP program recognizes the best new ideas in networking and provides them with greater visibility within the Internet Engineering Task Force (IETF) and Internet Research Task Force (IRTF) communities. 

    Two ANRP presentations, expected to spark discussion among the engineers, network operators, policy makers and scientists that participate in IETF meetings, will be part of the IRTF Open Meeting session of the IETF 111 meeting at 2130 UTC on 26 July 2020. Registration for the IETF 111 meeting is currently open.

    Rüdiger Birkner of ETH Zürich will present on research into automating network specification (a set of policies) and verification, which promises to make networks more reliable and secure. The Config2Spec system synthesizes a formal specification of a network given its configuration and a given failure model. Mining network specifications from existing network configurations avoids a major barrier faced by network operators: writing formal and precise descriptions of the intended network behavior.

    Sadjad Fouladi of Stanford University will describe Salsify, a new architecture for real-time Internet video. Salsify tightly integrates a video codec and a network transport protocol, allowing it to respond quickly to changing network conditions and avoid provoking packet drops and queueing delays. With real-time video becoming increasingly important for cloud video gaming, teleoperation of robots and vehicles, as well as video conferencing, this approach avoids shortcomings of current systems, which do not react quickly enough to network variations, resulting in network congestion that leads to stalls and glitches in video.

    A live stream of the session will be available on the IETF YouTube channel. For those interested in more applied networking research, registration for the Applied Networking Research Workshop (ANRW2021) online 26-30 July is also open.

    The ANRP is supported by the Internet Society and the IRTF, and sponsored by Comcast and NBC Universal.
