移动边缘网络中基于用户移动的服务功能链迁移策略
Migration Strategy of Service Function Chain Based on User Mobility in Mobile Edge Networks
摘要
Abstract
Mobile edge computing(MEC)provides ultra-low-latency and high bandwidth services to mobile users through deploying servers at the edge of the network and providing computation and storage resources.Along with the MEC technology,network function virtualization(NFV)can implement service function chain(SFC)in the MEC servers to improve the user experience.In order to ensure the quality of service(QoS)of the network,the SFC should be migrated to the applicable edge servers while mobile users move across the base stations.The authors propose a SFC migration policy considering the resources capacity constraints to achieve seamless migration of mobile user services as well as minimizing the sum of the end-to-end delay and the running costs of the user services.The simulation results show that the proposed scheme has better effectiveness and efficiency compared with the existing schemes.关键词
