Dynamic Service Function Chain Deployment in NFV-enabled Offshore Edge Computing Networks
TL;DR: design a scheme to solve dynamic SFC deployment problem in the offshore edge computing network
Abstract: Network function virtualization (NFV) has gained significant attention as an important paradigm in network service provisioning. In an NFV environment, network services are provided flexibly by deploying service function chains (SFCs) dynamically, which consist of multiple virtual network functions (VNFs) arranged in predefined order. In this paper, we formulate the dynamic SFC deployment optimization (DSDO) problem in the NFV-enabled offshore edge computing network, by jointly optimizing VNF deployment and routing to maximize the service acceptance rate. An SFC deployment scheme, named betweenness centrality and resource availability based dynamic SFC deployment (BR-DSD) scheme is proposed to solve the optimization problem. The proposed BR-DSD scheme aims to allocate resources for SFC deployment by considering both network resource availability and betweenness centrality. Simulation results demonstrate that the proposed BR-DSD scheme outperforms baseline schemes in terms of service acceptance rate.
