Research on dynamic load balancing of data center network based on openflow technology

Firstly, this article recommends the principle of DLB algorithm, then describes the DSLB algorithm designed for the improvement of DLB algorithm, and proposes a dynamic scheduling load balancing algorithm on account of data center network fat tree topology. This algorithm mainly improves the DLB load balancing algorithm to reduce the possibility of network congestion caused by DLB algorithm in the real data center network environment. According to the available bandwidth of all possible upload paths and send paths, the DSLB algorithm chooses the best transport path for the traffic, so as to better solve the problem of local network congestion caused by DLB algorithm the traffic load balance of the core network provides a better solution. This paper analyzes and compares the performance of DLB and DSLB, and proves that the load balancing effect of DSLB is better.
