Abstract

Software Defined Networking (SDN) is a new networking paradigm in which the control plane and data plane are decoupled. Throughout the recent years, a number of architectures have emerged for protocol-independent packet processing. One such architecture is the Protocol Independent Switch Architecture (PISA). It is a programmable and protocol-independent architecture composed of a number of Match and Action stages. Inside each of these stages is a crossbar to generate the search key and another crossbar to provide the input to the Action Units. In this paper, we design and explore alternative interconnection schemes with the aim of finding the most area- and power-efficient interconnection structure. Moreover, we propose further modifications to the interconnection structure, as a result of which the on-chip area of both match and action crossbars will be reduced by more than 70 % and power dissipation will be reduced by 25.8 % and 23.1 % for match and action crossbars respectively.
