Welcome to my web page! (Hand-crafted in simple HTML as Berners-Lee intended.) I am working on a variety of interesting research projects in Networking and Computer Systems. I founded the Mininet project, which creates instant virtual networks on your laptop (or other machine) for Software-Defined (and traditional) Networking research, development and teaching, and am currently technical lead for the Mininet-Optical project, which extends Mininet to emulate lightpath networks, as part of the COSMOS/COSM-IC projects at Columbia University. I have previously contributed to the ONOS and FAUCET SDN controller/network OS projects, as well as the OpenFlow SDN protocol.
Research and Publications
Mininet (including extensions such as Mininet-Optical) has been used for many dozens of research projects and publications presented at SIGCOMM, OFC, SOSR/HotSDN, HotNets, and elsewhere. Many student projects using Mininet (and other systems) to reproduce network research may be found here.
The following are some of my publications and presentations relating to Mininet and other systems I've created or worked on:
