Abstract: In this paper, we study the deployment problem of distributed dedicated protection services in
mobile edge computing. To minimize the total delay, we develop an Integer Linear Programming (ILP)
model and efficient polling based heuristic algorithms. Simulation results show that the proposed double
polling based algorithm can effectively reduce the total delay of all services and balance loads of the MEC
servers.
Key words: mobile edge computing; distributed services; dedicated protection; polling

随着第五代移动通信系统(5th Generation Mobile Networks,5G)技术成熟，诸如物联网、
车联网等资源密集、时延敏感型业务快速增长。移动边缘计算（Mobile Edge Computing,
MEC）通过在网络边缘部署边缘数据中心，就近为用户提供计算和存储资源，被认为是承
载这些新兴业务的重要技术之一[1]。同时，MEC 也存在单个边缘数据中心内计算和存储资
源有限，缺乏为大量并发业务提供服务的能力。因此，MEC 中存在一类业务可以通过切分
