VNE-ABC:Virtual Network Embedding Based on Artificial Bee Colony Algorithm

To overcome the high cost and low efficiency faced by virtual network embedding,a binary combinatorial optimization model and a virtual network embedding algorithms based on artificial bee colony(VNE-ABC) were proposed.The objective function of VNE-ABC was to reduce the costs of substrate network.Resultsshow that the costs of substrate network are reduced,and the success rate,average revenue of embedding and average usage of links are increased compared with the existing virtual network embedding algorithms.
