ABSTRACT
Conventional routing protocols such as BGP and OSPF are mature paradigm for dealing inter-domain internet routing. However, distributed nature of these protocols creates scalability, security and policy enforcement issues in Autonomous Systems. Software Defined Networks (SDN), new emerging networking concept, is seen as a solution of existing issues. In SDNs, network core is now being thought as composed of two separate planes: the control plane and the data plane. In SDN, routing is a generally implemented on the control plane in a centralized way. Information are exchanged between centralized controller and distributed data path for the calculation of routing paths and taking routing decision on the base of shared information. In this paper, we focus on the commonly used strategies for routing in SDN, in addition, we also discuss their implication in today's network.
