Research on Partition Domain Hybrid Carrying Group Scheduling Based on Reconfigurable Service Carrying Network

Network is rigid and close in the traditional technology system, which is not meeting intending abundant different business of scale application. So flexible network technology system facing on service providing is proposed, which change traditional close coupling connection of client business、network service and network foundation facilities to loose coupling connection. Then it can guarantee Quality of Service (QoS) by constituting Reconfigurable Service Carrying Network (RSCN) based on network resource slices. On above technology background, this paper proposes the idea of partition domain schedule after analyzing the requirement of switching fabric from mapping result of RSCN. It constructs crossbar switching resource slicing model by selecting closing part crossbar switching point. It proposes Hybrid Carrying Group Scheduling (HCGS) algorithm. And deduces Smoothed Deficit Round-Robin (SDRR) in the carrying group, input port scheduling algorithm based on timestamp in one carrying domain and output port scheduling algorithm of crossbar switching point. And proves that HCGS algorithm has better time delay and Worst-case Fairness Index (WFI) fairness performance. Then it uses SPES to realize emulation of HCGS algorithm, the result of emulation is that partition domain HCGS algorithm has optimizing time delay and traffic bandwidth fairness performance based on uniform Poisson traffic source, and has 100% throughput based on non-uniform diagonal admissible traffic source.
