A Kind of Dynamic Bandwidth Allocation Scheme Suitable for MPEG Video in Broadband Network

In view of bandwidth requirements in ATM (asynchronous transfer mode) network, a kind of dynamic bandwidth allocation scheme has been proposed. It solves the problem of low bandwidth utilization ratio caused in VBR (variable bit rate) MPEG (Moving Picture Experts Group) video transmission, the simulation experiment curve indicates that with the increase of already bandwidth value, the average cell loss factor reduces obviously, which satisfies the demand of all connection bandwidth as try as possible. The result indicates that the QoS (quality of service) of this plan has achieved 10
