OLiMPS – OpenDaylight – Addressing a yet unsolved issue in LHCONE, namely the efficiency in interconnecting multiple network domains over more than one connection, Caltech is investigating and has made significant progress in developing the use of multipath connectivity through OpenFlow networks. In the OpenFlow Link-layer MultiPath Switching (OLiMPS) project, funded by DOE/OASCR, the group has developed an OpenFlow controller based on Big Switch’s Floodlight open-source controller. To this end, we have significantly improved the basic controller towards a more flexible and production-ready version. Specific improvements include a more versatile and extensible internal architecture and configuration management features, an improved command line interface, and a range of advanced features.

Later in 2014 through Cisco Research funding, the code was partially converted to the OpenDaylight SDN platform as was demonstrated in SC14 conference. Currently the code is written for the Hydrogen release, however it will be matured for the Helium release in the coming months during the year 2015.
