摘要
针对多芯光纤空分复用弹性光网络中物理损伤导致网络的频谱利用率低与带宽阻塞率高的问题，提出一种物理损伤感知的业务动态路由和资源分配方法.在路由阶段，设计考虑路径跳数、可用资源和路径上链路资源利用率的动态路径资源评判公式，选择负载均衡和资源占用较少的候选路径.在频谱和纤芯分配阶段，设计满足业务串扰和非线性阈值的纤芯和频谱分配方法，最小化资源分配碎片值.仿真结果表明，当业务负载为900 Erlang时，与其他算法相比，本文所提方法的带宽阻塞率至少降低16%，频谱利用率提高3.02%以上.
Abstract
In order to solve the problems of low spectrum utilization and high bandwidth blocking probability caused by physical impairment for space division multiplexing elastic optical networks(SDM-EONs)
a physical impairment-aware dynamic routing and resource allocation(DRRA-PIA) method is proposed. In the routing stage of DRRA-PIA
by considering the path hops
available resources and link’s resource utilization of the candidate path
a dynamic path resource evaluation formula is designed to select the candidate paths with balanced load and less resource occupied for the request. In the phase of spectrum and core allocation
a method of core and spectrum allocation is designed to meet the limits of cross-talk and nonlinear impairment threshold
and minimize the resource fragmentation. Comparing with other algorithms
the simulation results show that DRRA-PIA method can decrease the network’s bandwidth blocking probability at least 16% and improve the spectrum utilization more than 3.02% when the traffic payload is 900 Erlang.
