End-to-End Transmission Performance Optimization Based Routing Selection Algorithm for Software Defined Networking

Abstract

Software-defined networking (SDN) is a new networking paradigm enabling innovation through decoupling control plane from data plane and providing programmability for network application development. Specific research focus has been placed to achieve route optimal selection in SDN scenario. In this paper, we study the problem of route selection for a user flow in a SDN scenario consisting of a number of switches and propose an end-to-end transmission performance optimization based routing selection algorithm. We jointly consider the characteristics of user flow and service capability of the network, and formulate the arrival curve of user flow and the service curve of switches by applying Network Calculus theory. The transmission performance of user flow, defined as effective bandwidth is evaluated and the route offering the maximum effective bandwidth is selected as the optimal route. Numerical results demonstrate the effectiveness of the proposed algorithm.
