Simulation model of the OpenFlow system based on the OpenFlow switch specification 1.0, developed at the University of Würzburg.

Software Defined Networking (SDN) is a new paradigm for communication networks which separates the control plane from the data plane of forwarding elements. This way, SDN constitutes a flexible architecture that allows quick and easy configuration of network devices. OpenFlow is currently the most prominent approach which implements the SDN concept and offers a high flexibility in the routing of network flows.

The model was originally presented at the 6th International Workshop on OMNeT++ (Cannes, 2013) by authors Dominik Klein and Michael Jarschel, for INET-2.0 and OMNeT++ 4.2.

Porting to newer OMNeT++ and INET versions has been done by other teams in forked GitHub repositories:

• https://github.com/inet-framework/openflow (semi-official)
• https://github.com/CoRE-RG/openflow (OMNeT++ 5.5.1 and INET 3.6.6, also extended for use with CoRE models)
• https://github.com/danhld/openflow (OMNeT++ 5.1 and INET-3.6.0)
