Abstract

In this paper, we present an adaptive smoothing strategy to pre-mark packets of multimedia stream over packet networks with Differentiated Service supported. This paper focuses on the basis of usage charging and of network resources utilization. In contrast of transmitting all packets at the premium class, the proposed strategy only pre-marks a portion of the packets as premium to accommodate users' expectation when the network is congested. To provide steady perceptual quality, the proposed strategy adopts the smooth pre-marking scheme which scatters the possible continual packet loss to conform the soft loss guarantees. The implementations are made for the CBR and VBR traffic including audio and video stream respectively. Finally, the performance results evaluated in the physical testbed will be given.
