Enhancing the ns-3 Network Simulator with
OpenFlow 1.3 technology support.

About the module

The OFSwitch13 module enhances the ns-3 Network Simulator with Software-Defined Networking (SDN) capabilities. OFSwitch13 supports OpenFlow protocol version 1.3, bringing a switch device and a controller application interface to the ns-3 simulator, as depicted in the figure below. With OFSwitch13, it is possible to interconnect ns-3 nodes to send and receive traffic using the existing CSMA and virtual network devices. Extending the controller application interface allows users to implement any desired control logic to orchestrate the network. The communication between the controller and the switches happens over standard ns-3 protocol stack, devices, and channels. The OFSwitch13 module relies on the external BOFUSS library that provides the switch datapath implementation and the support for OpenFlow messages in wire format. Please refer to the documentation for details about the module design, installation, and usage.
