SDNi- The New and Improved Hybrid Software Defined Networking Architecture for Inter-Domain Routing

Abstract

The evolution of the Next Generation Networks have recently received attention by researchers in the academic community and followed –up with various proposed models on this hot topic- "Software Defined Networks”. Software Defined Networking supported the centralization of the routing control logic of the management plane for intelligent networks. In this paper, we present a holistic view of the various challenges that comes with the framework and standardization activities while focusing on the technical perspectives rather than the financial and political view of intelligent traffic handling bearing in mind the network loads and other performance metrics. The Hybrid Software Defined Networks (SDN) explores a new direction to this research in Inter-Domain Routing Network Application with the introduction of SDNi main idea and exchanged states. This gives us insight over multiple transports network protocols that controls the internetwork. We analyse the associated trade-offs beginning from the promises of Software Defined Network Interconnection {SDNi} within a domain and gradually explore the benefits and challenges in our survey.
