“…Firstly, most current solutions, such as the ones presented above [1][2][3][4][5], have not taken practical condition of network resource into account and in their study the bandwidth resource is supposed to be unlimited. So under practical multi-user condition, an adjustment collision may be produced when several users request to increase the bandwidth simultaneously while the available bandwidth resource is insufficient.…”

In this paper, a practical dynamic resource allocation scheme for real-time variable bit rate (VBR) video transmission is investigated. This scheme uses time-domain adaptive linear prediction, instead of the conventional size prediction of I-, P-and B-frames, to forecast future bandwidth requirement in time. Media delivery index (MDI) is used here as QoS measurement and complementary reference for adjustment. Besides, considering that the practical multi-user application may arouse adjustment collision, an adjustment priorities classified strategy based on the user-level classifications is put forward. Last, a test-bed based on the proposed scheme is constructed and the experimental results show that the bandwidth effective utilization has increased by 20%-60% compared to a fixed service rate with QoS guaranteed and no collisions.This full text paper was peer reviewed at the direction of IEEE Communications Society subject matter experts for publication in the IEEE "GLOBECOM" 2008 proceedings.978-1-4244-2324-8/08/$25.00

“…Therefore, network resource must be periodically renegotiated and used as minimal as possible with a given QoS. Trying to meet this challenge, the online dynamic allocations are desirable and several relevant methods [1][2][3][4][5] have been proposed.…”
