The design of multi-path service over a virtual network

Virtualization has been proposed as a way of overcoming the growing problems of Internet. Within a virtual network, customized routing protocols can be implemented and deployed in the programmable router. This paper presents the design and evaluation of a multi-path service prototype over virtual network, which employs source-destination based multi-path routing mechanism and a bandwidth allocation algorithm. Our simulation experiments show a massive increase in throughput with low loss tolerance and resource utilization compared with the conventional network running OSPF.
