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。
To improve the energy efficiency of optical interconnection between data centers, an energy efficient routing algorithm for hybrid path transmission with service-duration awareness is proposed for anycast services. In order to reduce the number of new optical paths and working components, single-path transmission is preferred, and multi-path transmission is the target of minimizing transmission energy consumption if traffic is blocked. In addition, a service grooming strategy based on spectrum reservation is introduced to reduce protection bandwidth and optical transceiver overhead. The simulation results show that compared with the traditional energy-efficient routing algorithm, the proposed algorithm can significantly reduce the network energy consumption and effectively avoid the excessive increase of the service blocking rate, and achieve the balance of network energy consumption and performance.
