混合业务模型下的光突发调度

Scheduling of optical burst switching based on hybrid traffics model

分析了多路共享可以改善长相关特性的自相似业务模型在长队列缓存模型下的排队性能 ,有效降低Hurst参数 .在长期相关 (LRD)和短期相关 (SRD)的混合业务流模型下 ,提出了采用少量光缓存的多链路共享光突发交换方案 ,并在模拟仿真中 。

Based on the investigation of the blocking performance of long range dependent (LRD) traffic in optical burst switching (OBS) network, an OBS scheduling scheme-multi-links shared with some FDL buffers scheme was proposed. The optical analysis and performance simulation indicated that the scheme would reduce down the length of queues and Hurst factor, and improve the blocking performance based on the hybrid traffics model under SRD and LRD.
