Abstract

In the context of network function virtualization (NFV), the existing virtual network feature (VNF) placement algorithm is difficult to optimize network energy consumption and quality of service at the same time. This paper first constructs a network overhead. Optimize the problem model. Based on the model, this paper designs a VNF placement and routing algorithm combining genetic algorithm and simplex method. The algorithm combines the traditional genetic algorithm with the simplex method with strong local search ability, thus overcoming the problem that the traditional genetic algorithm is easy to fall into the local optimal solution. Simulation experiments show that compared with other deployment algorithms, the proposed algorithm can effectively optimize network delay and network energy consumption.
