| 分析了利用Container解决自动导引车(Automatic Guided Vehicle,AGV)移动而导致的资源和延迟失配问题的可行性，采用了C-RAN(Cloud-Radio Access Network)、吉比特无源光网络、光城域网和云数据中心在内的融合网络架构。通过AGV在小区的停留时间以及AGV移动后所处的空间位置，设计了同时最小化服务时延和迁移开销的双目标动态容器迁移(Dynamic Container Migration,DCM)优化框架，最后提出了基于AGV时域和空间位置信息的自适应Container迁移算法(Adaptive Container Migration Algorithm based on Time-domain and Location Information,ACMA-TLI)。仿真结果验证了所提算法在迁移时延、迁移开销和资源均衡等方面的优势，且与对比算法相比在平均延迟方面的提升可达124 s。 |

| Abstract: |
| This paper discusses the feasibility of adopting container to solve the resource and delay mismatch caused by the rapid movement of automatic guided vehicle(AGV),and then introduces both the network architecture composed of cloud-radio access network(C-RAN),gigabit passive optical network and optical core networks and cloud data center.Besides,according to the AGVs stay time in the cell and the spatial location of the AGV after moving,a dual-objective dynamic container migration(DCM) optimization is proposed to minimize both the service delay and migration cost.An adaptive container migration algorithm based on time-domain and location information(ACMA-TLI) is proposed.The simulation results verify the advantages of the proposed algorithm in terms of migration delay,cost and resource balance,and compared with that of the benchmarks,the improvement in average delay can reach 124 s. |
