Towards a novel and optimal packet identifier design for SDN

Published: 22 August 2014 Publication History

Abstract

We argue that separate identifiers should be used in SDN for identifying users, packets for forwarding purpose, and packets for policy enforcement purpose. We discuss the requirements and challenges in designing such an identifier scheme and sketch its various components. We show that our design can minimize switch table sizes by enabling optimized aggregation, make table sizes stable and predictable, and honor legacy address assignment in existing networks.
