A Network Slicing Deployment Method for Guaranteeing Service Performance

摘要

In order to deal with the performance degradation caused by resource contention due to the sharing of physical resources between VNFs in the network slicing, we proposed a network slicing deployment method for guaranteeing service performance. Firstly, estimate the basic performance level of VNF from the perspective of resource supply and demand. Then select the candidate deployment servers for VNF, the candidate servers can guarantee the basic performance level of both new incoming and already deployed VNFs. Finally, to reduce deployment costs, our approach uses the candidate server on the shortest path as the final deployment server. The simulation results show that this method not only can reduce performance degradation on physical servers, but also can reduce operating costs.
