Barefoot Networks: The world’s fastest most programmable networks

This whitepaper describes the PISA (Protocol Independent Switch Architecture), an innovation in the processing of packets of data at high speed. PISA allows users to program the network for themselves, without any degradation in performance, using an open-source programming language. The paper discusses how programmable network systems can outperform fixed-function systems and lead to further innovations in networking. One result is that data-center networks can now evolve at the same pace as the applications running on their servers. Network behaviour can be captured in software, and transported across switches, and become a source of competitive advantage for the network owner Read More
