ONF Connect 2019

This presentation explores the evolution of SDN from OpenFlow to P4 and P4Runtime, outlining the key differences and advantages of each. Special focus will be placed on the value of the programmable match-action pipeline, the programmable parser and the OpenFlow and P4Runtime protocols, including a look at specific commercial implementations of each, and the refactoring of a specific commercial OpenFlow solution into a P4 Runtime solution. Key benefits in this transition will then be examined such as increased flexibility responding to new customer requirements and shorter time to market for implementing new features.
