Source routed forwarding with software defined control, considerations and implications
Mourad Soliman, Biswajit Nandy, Ioannis Lambadaris, Peter Ashwood-Smith · 2012
The research introduced in this paper focuses on controller scalability and performance issues in Software-Defined Networks (SDNs), and discusses a new routing scheme that leverages a variation of Source Routing for use in OpenFlow-based networks. The research aims to reduce the state needed to be distributed to the network devices by the controller(s) in SDNs, and in return improve the scale, convergence time, fault tolerance and cost of such network architectures.
