In designing this scheduling algorithm , we not only consider the qos requirement of real - time serivce , but also consider the transmission request of non - real - time service 在算法的设计中不仅考虑到了实时业务的qos要求,同时也兼顾非实时业务的传输请求。
Reservation based dynamic bandwidth allocation scheme still adopts the concept of uniform spacing , and the access of request slot adapts to loading situation , which improves the non - real time services 动态带宽分配算法自适应于系统的负载状况,最大限度改善了非实时业务的性能。
Stream transport mechanism is explored for delay - sensitive realtime traffic while comfirm retransmition mechanism is proposed for non - realtime traffic . these strategies optimize system performances and provide qos guarentees 针对实时业务对时延敏感的特性,采用流传输机制;针对非实时业务分组丢失敏感的特性,采用传输层确认重传机制。
Through the adjustment and optimization of the parameter , the proposed algorithm can guarantee the qos of the real - time service and maximize the system capacity at the same time . in order to demonstrate the performance of the proposed algorithm , we compare our algorithm with m - lwdf 通过参数的调整与优化,该算法可以保证实时业务的qos要求,并且可以在减少实时业务分组时延和增大非实时业务吞吐量之间寻找最佳的平衡点。即尽可能的优化系统吞吐量。
One suits for non real time traffic and the other for real time traffic . in this paper , we focus on m - lwdf which is an interesting algorithm for providing streaming services on hsdpa because it includes in the priority computation not only the instantaneous channel quality experienced by the user , but also the packet queuing delay 其次,按照支持实时和非实时业务来分类讨论无线分组调度算法,确定支持实时业务的m - lwdf算法为本文重点研究对象,分析了在固定比特速率情况下m - lwdf算法的性能,并对其作了修正。
