A New Buffer Management Scheme for Multimedia Terminals in Broadband Satellite Networks

In the recent years, there has been a growing interest in broadband satellite networks. Broadband satellite networks are designed to provide the required qualify of service (QoS) for multimedia applications while maximizing the bandwidth and power utilization efficiency of the satellite channel. They incorporate appropriate call admission control (CAC) process, policing mechanism, and medium access control schemes for regulating access to the satellite channel from multimedia earth terminals. This motivates the need for an appropriate buffer management to control the congestion at the earth terminal buffers so that the compliant traffic is ensured to receive its required QoS. In this paper, we propose a novel Head of Line Priority Cell Discard (HoL- PCD) buffer management mechanism at the earth terminal buffers, that preserves QoS for compliant traffic at the expense of non compliant traffic, and improves the overall delay performance of the network. Our simulation model includes a GE...
