Jitter reduction in CBR MPEG-2 transport stream packet communications overlossy ATM network

For the reduction of the jitter originated from the cell losses in ATM netw ork when CBR traffic is transferred on AAL5, we propose that the receiver m aintain a timer whose expiration time is proportional to the cell time of t he source traffic plus the standard deviation of the 1-point CDV of the rec eived. ATM cells. Moreover, to enhance the granularity of the error or loss detection mechanism in the AAL5 PDUs, pre also modified the AAL5 PDU trail er fields so that each cell comprising the AAL5 PDU has a sequence number f ield. The simulation results show that the peak-to-peak PDV of the AAL5 PDU by the proposed method is less than 69.4% to that by AAL5. Moreover, the A AL5 user receives the same or more error-free transport packets in the prop osed algorithm than those in the ITU-T AAL5 for the same network simulation environment.
