灵活栅格光网络中业务公平性的研究

Research on fairness of different bandwidth services in flexible grid optical networks

针对灵活栅格光网络中的业务公平性问题,提出业务分割-粗略分段(SS-RP)策略的频谱分配方案,其基本思想是将链路的频谱资源分为两部分,分别传输低速和高速业务,同时将高速业务分割成低速业务传输,以提高高速业务被服务的概率。

In order to address the fairness issue of different bandwidth services in flexible grid optical net- works, the paper proposes the Service-Split Rough-Partition approach, which partitions the spectrum resource of links for dedicated use by low bit-rate and high bit-rate demands, and splits a high bit-rate demand into two low bit-rate sub-demands that need equal bandwidth, making the high bit-rate demands more easily allocable in the network.
