Dynamic Bandwidth Allocation for VBR Video Transmission

Dynamic Bandwidth Allocation for VBR Video Transmission

To guarantee quality of service QoS , the requirements for video transmission, such as delay and cell loss rate CLR , are very stringent. These constraints are difficult to meet if high network utilization is desired. In this paper, dynamic bandwidth allocation algorithms are proposed to improve the bandwidth utilization. The first approach based on scene change identification, in which the ban...

On-Line Dynamic Bandwidth Allocation For Vbr Video Transmission

To guarantee quality of service (QoS), the requirements for video transmission, such as delay and cell loss rate (CLR), are very stringent. These constraints are difficult to meet if high network utilization is desired. In this paper, on-line dynamic bandwidth allocation algorithms, in which the bandwidth is adjusted based on the current frame size, are proposed to improve the bandwidth utiliza...

Dynamic bandwidth allocation for stored VBR video in ATM endsystems

The paper introduces a scheme for delivery of variable bit-rate (VBR) coded video from a video server over ATM networks. To solve the problem of long term variations in bandwidth requirements, a dynamic bandwidth allocation scheme is proposed. This is based on renegotiation of bandwidth during the duration of the call. An algorithm is presented, that determines optimized renegotiation points fo...

Dynamic Bandwidth Allocation for VBR Video Traffic Based on Scene Change Identification

To guarantee quality of service (QoS), the requirements of video transmission, such as delay and cell loss rate (CLR), are very stringent. These constraints are diicult to meet if high network utilization is desired. In this paper, dynamic band-width allocation algorithms, in which scene change identiication is incorporated, are proposed to improve the bandwidth utilization. The bandwidth alloc...
