Abstract:

From the perspective of packet forwarding performance, this paper studies the acceleration effect of DPDK on VNF and CPU resource consumption and the resource allocation problem of deploying multiple virtual network functions in a single physical node. A heuristic VNF resource allocation algorithm based on greedy algorithm is proposed. Further, aiming at the tidal phenomenon of network load, this paper proposes a scheme of automatic switching VNF instance based on network load. The experimental result shows that, compared with the traditional method, this scheme improves VNF performance by 20% under high load.
