Time-dependent applications using TCP often send thin-stream traffic, characterised by small packets and high inter- transmission-times. Retransmissions after packet loss can result in very high delays for such flows as they often cannot trigger fast retransmit. Redundant Data Bundling is a mechanism that preempts the experience of loss for a flow by piggybacking unacknowledged segments … Continue reading

Video users in a multicast group may be highly heterogeneous in terms of individual channel conditions and requirements for video transmission, making it a challenging task for the network to optimally configure the resource management. In this paper, we consider a mathematical model for the choice of the optimum number of transmission opportunities, based on … Continue reading

Practical shared bottleneck detection has proved to be a difficult problem. We present a novel passive approach using efficient estimates of time and frequency domain summary statistics. The approach is not CPU nor network intensive, and has numerous potential applications in the Internet. Simulations and tests over the Internet and 3G cellular network show its … Continue reading

Data-bundling is a useful technique that decreases the delivery delay of packet streams when they are transmitted over noisy channels and are subject to retransmission-based error control. In this paper, we investigate the packet delay statistics for a fully reliable selective repeat automatic repeat request (SR ARQ) where a data-bundling mechanism is employed. In more … Continue reading

Today many end hosts are equipped with multiple interfaces. These interfaces can be utilized simultaneously by multipath protocols to pool resources of the links in an efficient way while also providing resilience to eventual link failures. However how to schedule the data segments over multiple links is a challenging problem, and highly influences the performance … Continue reading
