Heuristics for SDN controller deployment using community detection algorithm
Bangzhou Liu, Binqiang Wang, Xiao-Qiang Xi · 2016
This paper defines several metrics to improve network performance, and proposes an approach of two steps to partition domains and deploy controllers for large SDN, reducing the complexity of multiple controller placement model compared with previous works. Firstly, the approach divides the network into several domains based on community detection algorithms. Then, the controllers are deployed in the domains separately considering control link transmission latency, reliability and controller load balance. Results show that this approach improves the load balance drastically compared with LPA, as well as network performance compared with CCP. In Internet2, the reliability index increases by 10% and the control link transmission latency decreases by 9% at most.
