24/5/13 at 16:00 in GS/102 (66-72 Gower Street).

title:  A Unikernel approach to OpenFlow architecture simulation and emulation

Abstract:

SDN , and its predominant implementation the OpenFlow protocol, provide a flexible mechanism for network developers to evolve network functionality without any modifications in existing network and transport protocols. Nonetheless, transferring SDN network designs in production networks is not a straightforward process. SDN-enabled hardware performance is under-documented, while there is a luck of tools providing insights on the impact of new control mechanics in large scale networks. In order to aid SDN developers in performance reasoning, we propose a novel OpenFlow large scale simulation and emulation platform, which we call SDNsim. SDNsim builds on top of the Unikernel library OS (http://anil.recoil.org/papers/2013-asplos-mirage.pdf) abstraction and provides a generic mechanism to describe network functionality. Using the compilation mechanism of the framework, users can build from their specifications either high precision event-driven simulations of the system or fast Xen-based emulations. In this talk I will provide a high level description of the Unikernel architecture, the design and performance of the SDNsim platform and, driven by our exploration in network control, I will present a demo of its functionality.
