ABSTRACT
Software Defined Networking (SDN) has been described as the hope and hype for the future of networking. Definitions vary, but one research direction is to separate the control plane from the data plane, introducing abstractions that can provide a global network view, a description of required behavior, and a model of packet forwarding. While the worthy goal is to address ossification of the Internet, the "S" for "software" in SDN perhaps unintentionally ossifies views of the respective roles of hardware and software. Specifically, it introduces an inbuilt assumption that there is relatively dumb switching hardware for high-speed packet forwarding, and relatively intelligent software running on processors for lesser-speed networking control. Programmable logic technology offers scope for 'soft hardware', with the potential to blur the distinctions between traditional roles. However, such technology must prove both its ability to deliver the necessary high performance and its ability to be programmed in a high-level manner. This talk will overview research that has been addressing these issues successfully, and will discuss its potential impact on the evolving view of SDN.
