Hi all.
Some months ago, Luigi Iannone suggested the idea of “putting together” TCMTF and LISP. TCMTF uses Tunneling, Multiplexing and header Compression of Traffic Flows (TCMTF) in order to save bandwidth and to reduce the amount of packets per time unit. (http://datatracker.ietf.org/doc/draft-saldana-tsvwg-tcmtf/) We have done some simulations, and we have just got accepted a paper to be presented in IEEE ICC 2013 conference in Budapest in June. A draft version is here: <http://diec.unizar.es/~jsaldana/personal/budapest_ICC_2013_in_proc.pdf> http://diec.unizar.es/~jsaldana/personal/budapest_ICC_2013_in_proc.pdf Taking into account that encapsulation is necessary in LISP, bandwidth can be drastically reduced in flows using small packets, which are typical of many real-time services, like online games, VoIP, etc. by means of header compression and multiplexing of a number of packets. The headers added by LISP are 36 bytes (20 IP + 8 UDP + 8 LISP), and this would be significant for small packets (e.g., a VoIP packet can be 60 bytes long). So multiplexing together a number of packets traveling between the same pair of networks can save a lot of bandwidth. We have obtained these results: - VoIP: 70% saving - First Person Shooter games: 54% saving - MMORPG games: up to 80% saving - Grouping TCP ACKs: 45% saving We have also studied the ability of the LISP framework to manage the signaling of TCMTF options. We think these results are interesting, so we wanted to share them here. Feel free to read the paper and discuss about it. Thanks a lot, Jose Saldana
