Abstract
The group streaming of flows (GSF) is proposed to graphics. transmit variable bit-rate (VBR) packet streams from multiple input inks to a single output link. The existing scheduling algorithms do not meet the properties of fairness and delay in the transmission of VBR traffic streams because the characteristic of VBR traffic is that the rate of traffic is different in different time periods. The scheduling feature of GSF is that the streams of flows are grouped together dynamically, and the service and arrival loads on the scheduler are estimated in each group. This grouping scheme reduces the in-accurate approximation of the current load of the server. Therefore, fair service of flows is achieved by competing the service within a group and among the groups. This reduces traffic distortion in the output link of switch or router. Simulation experiments using on-off traffic and MPEG traces show that the GSF improves both the fairness and delay properties. The prediction schemes-the mean & standard deviation and the regression approaches-are investigated to smooth the traffic, and then the degree of fluctuation after alleviating the video streams is examined in terms of burstiness.
