文摘

Software-defined networking (SDN) is an emerging architecture that offers advantages over traditional network architecture. Segment routing (SR) defines the path of information through the network via an ordered list of multi-protocol label switching (MPLS) mechanisms on the packet headers at the ingress device, and this system makes SDN routing management more simple and efficient. SR can also solve some scalability issues in SDN. In this paper, we propose a routing algorithm for SDN with SR that can meet the bandwidth requirements of routing requests. Our algorithm considers the balance of traffic load and reduces the extra cost of packet header size in a network. Simulation results show that the performance of our algorithm is better than that of previously developed algorithms in terms of the average network throughput and the average rejection rate of routing requests.
