Delay performance analysis of rpr ' s three priorities traffic 三种优先级业务的时延吞吐量性能分析
Low priority traffic 低级别业务
The concern problem is how to guarantee the qos ( quality of service ) of the high priority traffic while to reduce the delay of data traffic 如何在保证高优先级业务的qos ( qualityofservice )同时,减小数据业务的时延成为卫星网络资源调度所关注的问题。
But all of these algorithms in literatures concentrate in how to improve the qos of high priority traffic sacrificed the delay of ubr ( unspecified bit rate ) traffic 但是这些算法都集中在为高优先级业务提高qos而牺牲ubr ( unspecifiedbitrate )业务的平均时延。
It integrates the current routing mechanism and network management system , and can protect the higher priority traffic and achieve efficient resource utility at the same time 该机制将路由机制与网管系统相配合,区分不同应用的优先级和生存性要求,快速恢复受影响的高级别流量,同时又充分考虑资源的利用效率。
Therefore this paper proposes the delay equalization algorithm which can both guarantee the qos of high priority traffic and effectively reduce the delay of ubr traffic in broadband satellite network . it is based on the prediction and equalization the delay of vbr or abr traffic so that the saved slots can be allocated to ubr traffic . the approach of dynamic alternation slots between vbr and ubr traffic can improve the mean tdma frame utilization while reducing the delay of ubr traffic 因此本文在基于流量估计的资源调度算法基础上,提出了一种在宽带卫星网络下能够保证高级别类业务qos ,同时又能够有效地降低ubr业务时延的时延均衡( delayequalization )调度算法,它是基于对vbr或abr业务时延的预测,均衡时延的方法,保证vbr或者abr业务qos的同时,将节省的时隙分配给ubr业务。
