具不确定信息的延迟受限QoS路由研究

Research on Delay-Constrained QoS Routing with Uncertain Information

QoS路由的目的是找到一条或多条具有足够资源,以满足某种约束条件(如延迟,带宽等)的路径。在实际情况中,关于链路状态的信息并不总是确定的,这种不确定性对QoS路由的选择有着不可避免的影响。探讨其原因,在约束条件为延迟保证的前提下,讨论处理不确定信息的QoS单播路由算法。

QoS routing aims at finding one or more paths that have sufficient resource to satisfy some constraints, i.e. delay or bandwidth. In real world, the information about link status is always with uncertainty that will throw unavoidable impact upon the selection of QoS routing. We will discuss its reason and discuss the corresponding QoS unicast algorithms under the precondition of delay guarantee.
