  • Virtual network embedding (VNE) is a crucial technology for network virtualization to allocate network resource. Virtual network request in which node and link resource have great disparity will lead to unbalanced resource distribution and lower acceptance ratio of virtual network requests. In this paper, we provide a virtual network embedding algorithm for load balance with various requests. It maps virtual nodes to substrate nodes of which node link residual resource ratio is closest to that of virtual nodes, and then maps the virtual link to physical path using shortest path first algorithm with the link node residual resource ratio constraint. Simulation shows that the provided algorithm can get higher acceptance ratio and network resource utilization for load balance.
