| 摘 要： | 为提高资源利用率和降低网络阻塞率,提出一种应用于光网络中带有负载感知(LA)的低开销保护机制,充分考虑了网络共享风险链路组(SRLG)的约束条件,建立整数线性规划(ILD)模型对共享通道保护策略与LA技术进行联合优化。仿真表明,与传统机制相比,所提出的机制能够有效地降低网络阻塞以及保护开销,使网络中的流量更加均衡。

| Abstract: | In order to increase the resource utilization rate and reduce the blocking probability,this paper proposes a novel shared-path protection design by introducing the load-aware theory.Under the constraint conditions of shared risk link group,we establish the integer linear programming model to optimize jointly the protection strategy and the load balance technology.The simulation results show that compared with the traditional protection mechanisms considering wavelength consistency or not,the novel mechanism... |
