Project : ONOS (Open Network Operating System): It's a carrier grade SDN open source Operating system solution. This project adds Border Gateway Protocol with Link State Distribution extension (BGP LS) , BGP flow spec and Route policy distribution as a southbound plug-in and application in ONOS controller to collect the topology information of the network. This network topology can be used by some applications like PCE would benefit from visibility outside one area or Autonomous System (AS) in order to make better decisions for path computation.

Platform : Java, apache Karaf, maven on Linux, JSON, REST, Git

Major Contributions :

• Implemented BGP application, REST and flow class for BGP flow spec and RPD.
• Implemented CLI to configure and display BGP-LS configuration.
• Implemented BGP-LS attributes like node, link and prefix.
• Implemented REST infrastructure to push configuration to distributed store and southbound BGP.
• Implemented flow specification RFC 5575 and Route policy distribution.
• Code reviews and open source mailing group query resolution.
