Abstract

In view of the low flow entry utilization rate caused by the current SDN when dealing with a large number of flows, the slow forwarding response and the current network scheduling algorithms might cause local network congestion and load imbalance, this paper proposed a multi-path scheduling algorithm SRMF based on segment routing. First, the SDN controller sent the initial flow entries according to the network topology links information. Then, it comprehensively considered the remaining bandwidth of the network links, the packet loss rate and the estimated bandwidth requirements of the flow to calculate the path weight. Finally, it selected the optimal path according to the path weight and installed the segment flow entries to the edge switches. Experimental results show that the segment routing technology has obvious advantages in terms of flow entries overhead compared with the general forwarding technology under multiple network topologies. Compared with Hedera and ECMP, SRMF algorithm has certain advantages in terms of end-to-end delay, delay jitter, network throughput and packet loss rate.
