Patent number: 10728139Abstract: Methods and apparatuses for building a programmable dataplane are described. Specifically, the programmable dataplane can work on a list of identifiers, such as those part of OpenFlow 1.5. Specifically, the programmable dataplane can be built by creating a virtual network graph at a controller node using binary identifiers such that a node is broken into an n-ary tree and the tree has 1×2 or 1×1 nodes.Type: GrantFiled: September 26, 2018Date of Patent: July 28, 2020Assignees: Indian Institute of Technology, Bombay, Defence Research & Development OrganisationInventors: Ashwin Gumaste, Aniruddha Kushwaha, Sidharth Sharma, Mahesh Jagtap
