Connection admission control with picture-type dependenteffectivebandwidths for VBR MPEG video traffic in ATM networks
Byeong‐hee Roh, Heejune Ahn, Jae Kyoon Kim · Electronics Letters · 1997
The I-picture starting time distribution of VBR MPEG video sources may significantly affect the cell loss characteristics of ATM multiplexers. The authors propose a new connection admission control (CAC) method which can reflect this effect. For CAC, the VBR MPEG video traffic is modelled as a composite sequence of three subsequences with different effective bandwidths according to their picture coding types. Experimental results show that the proposed method can fully reflect this effect due to the starting time distribution while also improving network utilisation significantly.
