Turning the tortoise to the hare: an alternative perspective on event handling in SDN

| Abstract | OpenFlow, the most popular software-defined networking proposal, decouples control from data path, and pushes control functionality to a software-based controller with a centralized view of the network. Such a design enables change and innovation by simplifying the implementation of control applications. A historically narrow interpretation of control and data planes, however, has led to unnecessary limitations on network applications that can be supported by OpenFlow. More specifically, applications handling frequent events are pushed outside the scope of SDN as: i) the controller cannot tolerate the high load; and ii) changing data path ASIC is an extremely costly and long process. In this paper, we present our perspective on this challenge. We believe these are non-intrinsic limitations that can simply be viewed as design challenges in areas such as state abstraction, event propagation, parallelism, and placement of network applications. We show how a consolidated software platform can be used to address these challenges, and how this design leads to a cohesive framework capable of accommodating applications with frequent events. |
