Ouroboros: SDN Beyond Flow - Tuple Matching
Liang Li, Ping Du, Akihiro Nakao (Univ. of Tokyo) NS2012-186
Abstract (in Japanese) (See Japanese page) 
(in English) The current OpenFlow switches only deal with L2-L4 headers and ignore L7 part of packet. Al- though it reduces the complexity of packet processing, it may conversely result in wasting potentially usable information for controlling flows, especially from applications’ point of view. Ouroboros is a programmable switch logic that not only lifts the limitation of regular OpenFlow switches using 15 tuples as the reference for packet switching, but also provides a highly flexible interface for users to conduct application-specific flow control according to packet content at arbitrary offset. In other words, users are practically granted the au- thority to utilize packet payloads and write handlers to establish matching rules in order to process desired actions for different application flows. For example, Ouroboros can penetrate deeply into packet, e.g., RTP, SIP protocol headers, or even further into the payload, to conduct packet switching. We implement a prototype of Ouroboros logic via Click [1] on FLARE [2] and perform preliminary evaluations.
