Abstract
Mobile Edge Computing (MEC) is an emerging network architecture that provides computing capabilities at the edge of the mobile network. Recent approaches tend to deploy MEC applications in the Network Function Virtualization (NFV) network. In the MEC-NFV environment, mobile network services are deployed as service chains, also known as Service Function Chains (SFCs). In this paper, we focus on the SFC placement problem in the MEC-NFV environment while guaranteeing availability. We design a backup model to improve SFC availability. Besides, we propose a Dynamic Programming (DP)-based algorithm to place SFC. Evaluation results show that our proposed solutions outperform the existing approaches in terms of availability guarantee and resource optimization.
