Time-Driven Early Discard (TED) to Improve the Fairness of TCP Congestion Control

Tags:
tcp - ip

Overview This paper proposes a novel adaptive AQM (advanced queue management) approach called Time-Driven Early Discard (TED). The basic underlying idea is to set a deadline on packet service time in routers, beyond which packets are discarded. TED is shown to improve fairness among TCP connections sharing congested links when the deadline is chosen proportional to their round trip time (RTT). TED is adaptive in limiting the throughput of only those connections that traverse congested links. In fact, as demonstrated by the presented results, TCP connections traversing parts of the network with enough available capacity can achieve the maximum throughput enabled by their transmission window as corresponding packets do not reach their deadline.

A second example is Redline Networks, which cares less about the content of the packets and more about ensuring they are transported in the most efficient manner possible across the ether. For example, F5 Networks (and their competitors, Alteon and...

Peter Cochrane's Uncommon Sense: Hype and Skype

On the other hand, when you send an email message via the internet your bits are transmitted in discrete packets that are often routed very differently, packet by packet. So the arrival times of packets can be widely distributed and vary on a...

Yet the tools to hugely increase the capacity of the links through and between exchanges are available. Now with the introduction of a huge hike in the capability of routers, there is no technical obstacle to radical changes in the availability of...

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

Routers ping each other, to see which pathway is congested, completely blocked or relatively open. The problems of packet loss, delay and jitter are exacerbated when voice traffic intermingles with packets from other applications.

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.
