A special session on Reducing Internet Latency will be arranged by RITE at the upcoming European Conference on Networks and Communications (EuCNC 2015) in Paris. The special session will be held on Tuesday June 30 before lunch and will feature four paper presentations: Internet Latency: Causes, Solutions and Trade-offs Reducing Transport Latency using Multi-path Protocols … 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
Two papers were accepted and presented during the last week of January at the IAB SEMI Workshop in Zürich, Switzerland. “Tunneling Through Inner Space” by Bob Briscoe, and “Ossification: a result of not even trying?” by Michael Welzl, Gorry Fairhurst and David Ros. 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
PhD Candidate Safiqul Islam was at the Capacity Sharing workshop at SIGCOMM Chicago in August 2014, given the best paper award for the paper “Coupled Congestion Control for RTP media”. The award was based on paper and presentation quality and will result in publication in ACM SIGCOMM´s Computer Communication Review. Find the paper … 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
Congestion occurs at a bottleneck along an Internet path; multiple flows between the same sender and receiver pairs can benefit from using only a single congestion control instance when they share the same bot- tleneck. These benefits include the ability to control the rate allocation between flows and reduced overall delay (multiple congestion control in- … Continue reading
HTTP is a successful Internet technology on top of which a lot of the web resides. However, limitations with its current specification, i.e. HTTP/1.1, have encouraged some to look for the next generation of HTTP. In SPDY, Google has come up with such a proposal that has growing community acceptance, especially after being adopted by … Continue reading
For many years Internet routers have been designed and benchmarked in ways that encourage the use of large buffers. When these buffers accumulate a large standing queue, this can lead to high network path latency. Two AQM algorithms: PIE and CoDel, have been recently proposed to reduce buffer latency by avoiding the drawbacks of previous … Continue reading
