摘　　要：为了减少云计算服务非再生能源(NRE)能耗,提出从DCs到核心网络中的节点接入段的下游服务迁移操作策略,允许在一个时间间隔/周期内从DC提供的服务连接进行迁移,并在下一个时间间隔从另一个DC提供服务连接。然而,连接服务迁移涉及信令开销,并且可能中断正在进行的服务。考虑到NRE能耗的节省和由于迁移而产生的成本(即惩罚),利用混合整数线性规划(MILP)优化模型和基于辅助矩阵的启发式算法,在线求解动态优化问题,并允许选取最优服务连接迁移。实验结果显示,所提算法可有效降低数据中心服务迁移的NRE能耗。The downstream service migration operation strategy from DCs to the access segment of the node in the core network is proposed to reduce the energy consumption of non-renewable energy(NRE)of cloud computing services,by which the migration of service connection provided by DC within an interval/cycle is allowed,and the service connection is provided by another DC within the next interval. However,the connection service migration involves signaling overheads and may interrupt ongoing services. In consideration of the saving in NRE energy consumption and the costs(i.e.,penalties) generated by the migration,the dynamic optimization problem is solved online by means of the mixed integer linear programming(MILP)optimization model and the heuristic algorithm based on auxiliary matrix, with which a selection of the optimal service connection migration is allowed. The experimental results show that the proposed algorithm can effectively reduce the NRE energy consumption of service migration of data center.
