IETF 87 NWC RG (Proposed) Minutes Wednesday, 31 July 2013 9-11:30am Chairs - Victor Firoiu (BAE Systems); Brian Adamson (NRL) participating remotely. This meeting was the second meeting of the proposed IRTF Network Coding Research Group (NWCRG). Victor Firoiu provided an introductory presentation outlining the research group motivation and goals along with some background history, challenges and opportunities for the application of network coding concepts into Internet systems. The following presentations were given: o Note Well o Agenda bashing o (Re)Introduction of Network Coding proposed Research Group - Victor Firoiu, BAE Systems, Brian Adamson, NRL The presentation provided an overview of the draft charter posted on the NWCRG Wiki page. o Application Fields and Implementation of Network Coding - Frank Fitzek, Aalborg Univ. The presentation highlighted the implementation of RLNC for distributed cloud storage, wireless mesh networks, and heterogeneous channel support. All three applications are realized by using the KODO library. o Kodo: Implementation and News on the Network Coding library - Morten Pedersen, Steinwurf ApS Presented novel developments and functionality of the KODO library allowing network coding development out of the box. Also presented were complexity reduction, energy saving strategies, sliding window and the possibility to use KODO with the NS3 simulator. A question was raised by Tim Sheppard regarding the license terms for non-commercial use, since it is not standard GPL. Morten replied that their license grants free use for all non-commercial purposes. Tim expressed reservations about the clarity of these licensing terms. o TCP Instant Recovery: Incorporating Forward Error Correction in TCP - Tobias Flach, USC, N. Dukkipati, Y. Cheng, B. Raghavan, Google http://tools.ietf.org/html/draft-flach-tcpm-fec-00 Described the TCP-IR algorithm at the sending and receiving ends, along with the required protocol changes. Discuss how this work relates to existing alternatives like Network Coded TCP, and has shown similarities and differences to achieving the same behavior with Multipath TCP. o Network Coded TCP (CTCP) - Douglas Leith, NUIM Univ. Describes CTCP, a portable user-space implementation of a reliable transport protocol using network coding and UDP. CTCP is designed to incorporate TCP features such as congestion control, reliability, and fairness while improving on TCP’s performance in lossy networks. Also presented experience and performance evaluation in both testbed and production wireless networks. o Broadcast With Network Coding: DRAGONCAST - Emmanuel Baccelli, Cedric Adjih, INRIA, Songyean Cho, Samsung http://tools.ietf.org/html/draft-adjih-dragoncast-00 Presented a Network Coding (NC) based broadcast protocol suitable mainly for wireless networks, including mobile ad hoc networks (MANET). It provides data dissemination from a single source, based on intra-flow network coding and for Internet Protocol (IP). It is designed to minimize the assumptions over the working environment and thus may operates over dynamically evolving environments. o Cooperative Network Coding scheme over harsh scenarios - Josu Bilbao, IKERLAN o Network coding for bi-directional IP-traffic over transparent satellites - Tomaso de Cola, Hartmut Brandt, German Aerospace Center (DLR) At the end of the meeting, there was a discussion about the proposed group, and various attendands expressed positive interest in the creation of this group. Lars Eggert expressed his support for the group as well. He also reminded the group about the IRTF policies regarding IPR disclosures, and the desire to have disclosures be more specific in the description of the covered areas. He also encouraged the group for a diverse participation. There were no objections to the proposed Charter. The meeting adjourned at 11:30am.
