L7Classifier: Packet Classification applying Regular Expression to Packet Payload
Shogo Ando, Akihiro Nakao (Univ. of Tokyo)
Abstract (in Japanese) (See Japanese page) 
(in English) Recently, there are many research efforts on Software-Defined Networking.
Although OpenFlow switches are considered one of the promising SDN technologies, they only handle Layer 2-4 (L2-L4) headers.
This processing is not intuitive for application developers and end-users.
In this paper, we propose L7Classifier, which is a technique for controlling the packets based on the payload of the Layer 7 (L7) instead of the L2-L4 header information.
L7Classifier holds TCP flow information and performs regular expression matching to packet payload.
If a packet in a flow matches a regular expression, the packets belonging to the same flow are controlled by the same rule, e.g., actions.
We implement and evaluate L7Classifier on FLARE node which is a programmable node using Click. We also evaluate the performance and show the possibility of operation in a network environment of 10 Gbps.
