Multi-constrained Routing Optimization for Data Center Network

Feng-jun Shang, Xing Chen


Server-centric data center (SCDC) architecture is a new data center architecture with high throughput, scalable architecture and high fault tolerance. Some SCDC-based routing algorithms had been proposed, but these algorithms have the following disadvantages:1) The most advanced routing algorithms in SCDC are only considering hop count in path selection;2) Traditional QOS multiconstrained routing algorithms usually find one available path and is oriented to the switches; 3) The current multi-path algorithm cannot guarantee the quality of the selected path. Therefore, we propose a multi-constrained routing algorithm in the data center network. The SCDC topology is used to reduce the complexity of the algorithm, and it has high possibility to find the correct optimal path.
