A Distributed Routing Approach for Datacenter-oriented Virtual Network

In the enterprise-oriented virtual network computing environment,it usually uses data center framework to organize the underlying physical resources and aggregates the distributing virtual machine resources by virtual network.It requires that the virtual network provide high-performance data transfer for the requirements of mass data processing.However,it's difficult for the existing virtual network routing approaches and data transmission technologies based on IP capsulation to ensure the efficiency of transmission.To solve the problem,an efficient and reliable virtual network solution DR-VNET on the underlying datacenter architecture is proposed in this paper.The solution is based on layer 3 virtual network,and adopts the distributed routing technology of virtual network in which the communication between virtual nodes needs only "one hop".This approach can improve data transmission efficiency and avoide the bottlenecks of the routing in the existing virtual network solution.It has been implemented in a virtual computing platform,and experiment results showed the promotion of transmission efficiency of the virtual network.
