Abstract

Abstract

With the introduction of Network Function Virtualization (NFV), the network functions of operator networks are no longer dependent on dedicated hardware devices, and service capabilities of carrier network are more resilient than ever. For more efficient use of resources in NFV-based operator networks, this paper proposes a construction policy of Network Service Chain (NSC). This paper aims to maximize the number of flows that the carrier network can accommodate, a mathematical model is established for NSC construction from the point of view of reducing resource fragmentation due to the unreasonable use of computing resources and network resources. A new greedy NSC construction strategy is designed, which combines the path selection and multiple VNFs deployment of NSC. Numerical simulation result shows that the proposed policy can accommodate more flows and achieve lower end-to-end data latency than the typical policies in the case of the same amount of resources, which improves effectively resource utilization of the general server and switch in operator network.
