Title Of Article :
Design and Evaluation of a Distributed SDN Control Plane Architecture
Abstract :
Software-defined networking (SDN) is a new networking paradigm which aims to decouple forwarding hardware from control decisions. Existing SDN architectures centralize control logic to networks, and, however, cannot meet the requirements of scalability and adaptability simultaneously. Issues are that SDN architectures must be able to scale and able to adapt to dynamic conditions. Therefore, in order to cope with large-scale and dynamically changing networks, new architectures are required and need to be highly flexible. In this paper, an architecture that organizes controllers in a distributed hierarchy is introduced. Design concepts are presented to highlight its operation modes. Simulations have been conducted using Mininet and preliminary results are reported to show that the proposed architecture could reduce setup time of flow initiation.
