In this paper, we term multimedia streaming application traffic ``stream flows'' and the other usual application traffic ``non-stream flows''. Many problems occur when both flows are aggregated on a shared link because different TCP and UDP behaviors cause negative interactions. One way to solve these problems is to isolate stream and non-stream flows to different classes. However, under conditions where traffic provisioning fails and the bandwidth allocation for each class is unsuitable for the traffic, the QoS will be worse than without isolation.
It is considered to change bandwidth allocation ratio adaptively, but it is hard to implement on large scale networks and impossible if the ratio is fixed. Therefore, we have proposed a dynamic class assignment method that maintains the QoS and that has a higher scalability than dynamic bandwidth
allocation schemes. It is workable on Diffserv AF PHB. The outline is as follows. Non-stream flows are classified into four classes, and statically assigned to four AF subclasses. Stream flows are dynamically assigned to four subclasses, taking conditions and interactions into consideration.
In this paper, we show the algorithm for our dynamic class assignment method and provide results of simulation experiments done on a small-scale intra domain model. The results show that our method provides constant qualities with stream and non-stream flows, adapting to changing traffic. |
