In this paper we analyze the packet loss process in a single server queueing system with a nite buuer capacity. The model we use addresses the packet loss probabilities for packets within a block of consecutive sequence of packets. In contrast to other work which used an independence assumption to compute the loss probabilities of packets within a block, we present an analytical approach that y...

We consider the adaptation of random early detection (RED) as a buffer management algorithm for TCP traffic in Internet gateways where different maximum transfer units (MTUs) are used. We studied the two RED variants described in [4] and point out a weakness in both. The first variant where the drop probability is independent from the packet size discriminates connections with smaller MTUs. The...

We consider the adaptation of random early detection (RED) as an active queue management algorithm for TCP traffic in Internet gateways where different maximum transfer units (MTUs) are used. We studied the two RED variants described in [1] and point out a weakness in both.

This paper proposes, describes and evaluates a novel theoretical framework for end-to-end video quality assessment of MPEG-based video services in hand-held and mobile wireless broadcast systems. The proposed framework consists two discrete models: A model for predicting the video quality of an encoded signal at a preencoding state by specifying the bit rate that satisfies a specific level of u...

This paper is devoted to further strengthening, in the current asymmetric information environment, informed level of operators about network performance. Specifically, view burst and perishability a packet loss event, better meet real-time requirements high-speed backbone performance monitoring, model for Packet Loss Measurement at access boundary Based on Sampled Flow (PLMBSF) presented this u...
