Abstract

This paper proposed an SFC(service function chaining) placement algorithm based on VNF(virtual network function) instance sharing to address the problem of difficult tradeoff between the deployment cost of VNF instances and forwarding cost in the process of SFC placement. Firstly, for multi-link SFC, it constructed the VNF and virtual link mapping model, and estimated the upper bound of the path deployment length to ensure the SFC delay. Secondly, within the limit of the path length, it maximized the number of the reused VNF instance as much as possible to balance the forwarding cost and the deployment cost of VNF. Finally, it obtained the SFC placement strategy. Compared with the existing SPH(shortest path heuristic) and GUS(greedy on used server) placement algorithms, the total operating expense of the proposed algorithm is 6.6% and 12.15% lower, and when the number of SFC increases, the service acceptance rate of this algorithm can reach 89.33%. The simulation experimental results show that this algorithm can effectively reduce the SFC placement cost while ensuring the quality of service.
