摘要

High speed networks provide real-time variable bit rate (VBR) service with diversified traffic flow characteristics and quality requirements. The VBR traffic has stringent delay and packet loss requirements. The burstiness of the correlated traffic makes dynamic management highly desirable to satisfy the Quality of Service (QoS) requirements. Buffer management in queueing systems plays important role towards effective control of QoS for various types of applications. In this paper, ADaptive Partial Buffer Sharing (ADPBS) scheme for priority queueing system is proposed and analyzed. The input to the queue has been taken using auto-regressive (AR) process of order 2 for MPEG-encoded VBR video traffic. The results of simulations indicate that dynamically controlled threshold in ADPBS contributes in reducing the packet loss of different priority classes as compared with static partial buffer sharing queue and first-in first-out queue based on threshold control parameters and the traffic type.
