Flexible QoS Control Using Partial Buffer Sharing with UPC
Summary :
To provide QoS guarantees for each connection, efficient scheduling algorithms, such as WFQ, have been proposed. These algorithms assume a certain amount of buffer is allocated for each connection to provide loss free transmission of packets. This buffer allocation policy, however, requires much buffer space especially when many connections are sharing a link. In this paper we propose the use of partial buffer sharing (PBS) policy combined with usage parameter control (UPC) for efficient buffer management and flexible QoS control in ATM switches. We evaluate the feasibility of the proposed method by solving a Markov model. We also show that using the proposed method, we can control the cell loss ratio (CLR) independently of the delay. Numerical evaluations are presented, which indicates the PBS combined with UPC significantly reduces the buffer size required to satisfy given cell loss ratios.
