| Abstract | Larger companies need more sites in the wide area network (WAN). However, internet service providers cannot obtain sufficient capacity to handle peak traffic, causing a terrible delay. The software-defined network (SDN) allows to own more programmability, adaptability, and application-aware, but scalability is a critical problem for merging both. This paper proposes a solution based on Protocol-Oblivious Forwarding (POF). It is a higher degree of decoupling control and data planes. The control plane uses fields unrelated to the protocol to unify packet match and route, and the data plane uses a set of general flow instructions in fast forwarding. As a result, we only save three flow tables on the forwarding paths so that each packet keeps a pipeline in the source route header to mark the next output ports. This solution can support a constant delay while the network expands. |
