Abstract

Software Defined Networking (SDN) designs are initiated with their own apprehensions and challenges that are needed to be addressed by researchers. A Controller, the main and the dominant network resource in SDN, has complex connections that lead to traffic overhead between other devices in the network and also from and to other Controllers. A Controller’s capacity of communications obtains will be grown when the network gets bigger. Controller scalability one of the biggest issues of SDN caused by this growth. This paper presents SDN with a new framework architecture based on addressing routing through multiple layers of controllers positioned and encompassed in two levels hierarchal sequent. As a result, an efficient resource allocation and scalability strategy are achieved. The framework is implemented and evaluated. Experimental results show their superiority by reducing the number of messages handled via the Super Intend Controller for each domain and sustained performance for the entire network.
