OpenFlow 1.1 Software Switch ---------------------------- This is an OpenFlow 1.1 [1] compatible user-space software switch implementation. The code is based on the original Stanford 1.0.0 reference switch [2], with the forwarding plane being completely rewritten to support OpenFlow 1.1. The implementation is feature-complete, and passes the available oftest 1.1 test cases [3]. The following components are available in the release: - ofdatapath: the switch implementation - ofprotocol: secure channel for connecting the switch to the controller - oflib: a library for converting to/from 1.1 wire format - dpctl: a tool for configuring the switch from the console [1] http://www.openflow.org/documents/openflow-spec-v1.1.0.pdf [2] http://yuba.stanford.edu/git/gitweb.cgi?p=openflow.git;a=tree;h=7f09f6a88d86883b516c99eb4058402eb07e5fd0;hb=d90824f0e8c3b6606d04e5a8813f03e89a6d0894 [3] https://github.com/TrafficLab/oftest11 Getting Started --------------- To build, run the following commands in the of11softswitch directory: ./boot.sh ./configure make To start the datapath, run the following commands: cd udatapath sudo ./ofdatapath --datapath-id=<dpid> --interfaces=<if-list> ptcp:<port> This will start the datapath, with the given datapath id, and interace list, opening a passive tcp connection on the given port. For a complete list of options, use the --help argument. To start the secure channel, run the following commands: cd secchan ./ofprotocol tcp:<switch-host>:<switch-port> tcp:<ctrl-host>:<ctrl-port> This will open tcp connections to both the switch and the controller, relaying OpenFlow protocol messages between the two. For a complete list of options, use the --help argument. You can send requests to the switch using the dpctl utility: cd utilities ./dpctl tcp:<switch-host>:<switch-port> stats-flow table=0 For a complete list of commands and arguments, use the --help argument, and consult the dpctl.h file [1].
