Abstract

Underlying network provides infrastructures for cloud computing in data centers. The server-centric architectures integrate network and compute, which place routing intelligence on servers. However, the existing multi-port server based architectures suffer from determined scale and large path length. In this paper, we propose FleCube, a flexibly-connected architecture on multi-port servers without using any switches. FleCube is recursively constructed on division of multiple ports in a server by means of complete graph. FleCube benefits data center networks by flexible scale and low diameter, as well as large bisection width and small bottleneck degree. Furthermore, we develop multi-path routing (MPR) to take advantage of parallel paths between any two servers. MPR adopts random forwarding to distribute traffic load and relieve network congestion. Analysis and comparisons with existing architectures show the advantages of FleCube. Evaluations under different degrees of network traffic demonstrate the merits of FleCube and the proposed routings.

6. Conclusion

In this paper, we propose FleCube, a flexibly-connected architec- ture for interconnecting multi-port servers. FleCube is recursively constructed on the division of multiple ports of servers. It is highly flexible and scalable to accommodate hundreds of thousands of servers with low path length and large bisection bandwidth. Themulti-path routing on FleCube takes advantage of parallel paths be- tween any two servers in FleCube. Results of comparisons and sim- ulations demonstrate the good performance of FleCube and our pro- posed routings under different degrees of network traffic.
