Abstract: Data centers are becoming increasingly important infrastructures for many essential applications such as data intcnsivc computing and largcscalc network scrviccs. According to the previous rcscarchcs, this paper prcscntcd a high1y scalable cylinder data center interconnection architecture, with a simple yet efficient routing scheme that maintains short path length in servers communications. It proposed fault tolerant and traffi}aware routing schemes to ensure balanccd load. Experiments were used to test the transmission and routing performance of the design. Also,fault tolerance and load balance were evaluated.
