A load balancing algorithm for solving multi‐objective virtual network embedding

Abstract

AbstractVirtual network embedding (VNE) is one of the most basic problems in network virtualization. VNE is to deploy virtual network resources to substrate network resources to solve the problem of network rigidity, which is essentially a problem of resource optimization. It can be divided into two stages: node embedding and link embedding. Previous embedding schemes focused on the algorithm research of single objective, but in the process of VNE, many factors need to be considered, such as the benefits, acceptance rate, substrate resource load, and so on. Therefore, this article considered the multi‐objective VNE algorithm, proposed a load balancing algorithm for solving multi‐objective VNE, took the node load value as one of the fitness functions, and introduced global resource capacity to measure the embedding ability of the underlying nodes, initialized the population, improved the embedding accuracy, and used group search algorithm algorithm for iterative optimization. Simulation results showed that the algorithm can balance the load, effectively improve the acceptance rate of virtual network requests, and improve the revenue of user service providers.
