Performance Analysis of TFRC Over Wireless Link With Truncated Link-Level ARQ

Tags:
quality of service

Overview In this paper, an analytical framework is proposed for evaluating the Quality of Service (QoS) of TCP-Friendly Rate Control protocol (TFRC) in hybrid wireless/wired networks. For the wireless network, a link-level truncated Automatic Repeat reQuest (ARQ) scheme is deployed to reduce the packet losses visible to the transport layer protocol. Two Discrete Time Markov Chains (DTMC) are introduced to analyze the network performance and the QoS of the TFRC protocol, in terms of wireless link utilization, flow throughput, packet loss rate, and probability of end-to-end delay exceeding a prescribed threshold. Extensive simulations are performed to verify the accuracy of the analytical results.

GPRS networks lose 43 per cent of data

Up to 43 per cent of data packets got lost on the way from the radio terminal to the mast, and the latency - or the delay between a request and a response - was up to five seconds. Conventional applications based on the TCP protocol that underlies...

VoIP primer: How it works - and what the jargon means

Any 'latency' - the delay in delivering the voice stream from the speaker to the listener - degrades the quality of the sound as does 'jitter' and 'packet loss'. The problems of packet loss, delay and jitter are exacerbated when voice traffic...

Live Webcast: Telecoms 2.0 - Where is telecoms heading?

In this webcast, our panel of experts will review where we are with next generation telecoms in the UK, working through the concept of 'Telecoms 2.0': - Realising the potential of Next Generation Networks - why it isn't just about the technology? - What attributes should firms be looking for in their telco partner? - Is the relationship between telco provider and customer changing? - What things need to happen to make next generation services a reality? - You say you want the supplier to change. Do you want to change too? - What is Telecoms 2.0?

Telecom 2.0: Mind over matter

ntl:Telewest Business believes that the role of the telco is evolving. Gone are the days when it was enough to simply focus on circuits and minutes, customers now need a far higher degree of interaction and look for suppliers who will talk business solutions with them.
