摘要 为提高数据中心间光互联网络的能效,面向任播业务提出一种具有业务持续时间感知的混合路径传输节能路由算法。为了减少新建光路和工作元器件数量,优先采用单路径传输;若业务阻塞则以传输能耗最小化为目标进行多路径传输。除此之外,引入基于频谱预留的业务疏导策略来降低保护带宽和光收发器的开销。仿真结果表明:与传统节能路由算法相比,所提算法在显著降低网络能耗的同时,有效避免了业务阻塞率的过度增加,实现了网络能耗与性能的平衡。 In order to improve the energy efficiency of optical interconnection network among datacenters,an energy-efficient hybrid routing algorithm with holding time awareness for anycast service is proposed in this paper.It gives priority to the single path transmission which aims at reducing new established light paths and working components;and the multipath transmission based on minimizing energy consumption will be used if traffic congestion occurs.In addition to that,the traffic grooming strategy based on spectrum reservation is also introduced to reduce the overheads involving in bandwidth and transponder.The simulation results show that the proposed algorithm can significantly reduce the network energy consumption and avoid the excessive increase of traffic blocking rate compared with the conventional energy-efficient routing algorithm.The balance of network energy consumption and performance is realized.
