Abstract
The QoS solutions for video transmission over IP network presently include integrated services (IntServ) [4], DiffServ [5], multiprotocol label switching (MPLS) [6]. Among them, the DiffServ is regarded as a dominant protocol for its flexibility, scalability, and capability of QoS guarantee. Traditionally, policing or limiting function was implemented in DiffServ by using srTCM (single-rate three color marker) [2] and trTCM (two-rate three-color marker) [3]. Proposed scheme improve the throughput of MPEG4 video transmissions over IP network. In this scheme, I-frames, P-frames and B-frames are marked as different service priorities according to transmission condition and their contribution to the perceived picture quality. Investigators used authentic MPEG4 video traffic traces to compare the performance of the proposed scheme with other exesting RFCs for MPEG video transmission, such as srTCM and trTCM, in a DiffServ network. Results show that proposed scheme improves the throughput of video transmission over IP network.
