Abstract

Reducing the routing table size to obtain better scalability of network is more and more important for data center networks in cloud computing era. In this paper, virtual hierarchical mesh networks with different agent selection methods of different subnets are proposed to solve the network scaling embarrassment problem. Theoretical analysis and simulation results show the multi-agent selection methods outperform the single one in terms of end-to-end latency and load balance.
