README

This project is my work with Professor Brad Smith at the University of California at Santa Cruz to develop a "partially-ordered Internet" using Dominant Set Multipath Routing (DSMR), Software-Defined Networking (SDN), and Multiprotocol Label-Switching (MPLS). This project is being used as my Master's project.

The project uses the Ryu SDN controller and runs in the mininet virtual network tool.

Note: after launching Mininet, the user must set the host's interfaces' MTU to be at least 4 bytes fewer than the switches' MTU (default 1500). This is because adding an MPLS header to a packet adds 4 bytes of data.

to launch the controller: $ ryu-manager controllerFile.py --observe-links

to launch Mininet using the provided custom topology: $ sudo mn --controller remote --custom TopoFile.py --topo TopoName --switch ovs,protocols=OpenFlow13 --link=tc

to view flows on a switch: sudo ovs-ofctl -O OpenFlow13 dump-flows <switch name>
