Adaptive Bandwidth Share Estimation in TCP Westwood

Tags:
bandwidth issues

Overview TCP Westwood (TCPW) is a proposed sender side modification of TCP congestion control. TCPW relies on bandwidth share estimation techniques to enhance congestion control over high speed and/or wireless networks. The bandwidth share estimation methods turn out to be critical to guarantee both throughput improvement and friendliness towards widely used TCP protocols such as NewReno. This paper proposes a new bandwidth share estimation technique, called "Adaptive Bandwidth Share Estimation", or ABSE. ABSE adapts to changing network congestion level, round trip times, and other relevant network conditions, as well as to the rate at which such changes occur. The throughput gain and friendliness of ABSE is compared with that of NewReno and previous estimation methods used for TCPW.

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?
