Abstract

In order to solve the problems of poor load balancing caused by dynamic scheduling in data center networks(DCN), this paper proposed a dynamic load balancing algorithm based on flow scheduling selection(DLBFSS). Firstly, DLBFSS calculated the equal-cost shortest path for each large flow on the congested link and removed the path with insufficient bandwidth. Then, the available throughput of each remaining path for large flows was calculated, and the path with maximum available throughput was selected as the optimal scheduling path. Finally, the congestion probability of each large flow was defined by considering the flow bandwidth and the load of the optimal path, and the congestion probability was used for large flow scheduling selection. The experimental results show that DLBFSS can reduce the network delay, improves the flow bandwidth utilization and ensures load balancing compared with ECMP(equal-cost multi-path) and typical large flow scheduling algorithms.
