RR-TCP: A Reordering-Robust TCP With DSACK

Tags:
switching

Overview TCP performs poorly on paths that reorder packets significantly, where it misinterprets out-of-order delivery as packet loss. The sender responds with a fast retransmit though no actual loss has occurred. These repeated false fast retransmits keep the sender's window small, and severely degrade the throughput it attains. Requiring nearly in-order delivery needlessly restricts and complicates Internet routing systems and routers. Such beneficial systems as multi-path routing and parallel packet switches are difficult to deploy in a way that preserves ordering. Toward a more reordering-tolerant Internet architecture, the paper presents enhancements to TCP that improve the protocol's robustness to reordered and delayed packets.

'Selfish' routers slow the internet

To improve how routers direct traffic, Roughgarden suggested they consider not only which route is least congested, but also how sending packets in that direction would affect that path. If the routers that direct the packets of data could be...

Peter Cochrane's Uncommon Sense: Circuit or packet, clean or dirty?

For non-real time applications such as email and delayed voice and video we can use packet switching where the digital information is broken up into small packets and directed one at a time, across the planet, using any available routing at the...

Indian telecoms explosion tempts Cisco

The carrier will be using Cisco 12000, 7300 and 7200 series routers and its Catalyst 4500 series switches. MPLS is a technology that tags IP packets and creates secure tunnels for traffic through the network.

Secure VoIP has arrived

TCP uses packet retransmission, which means that packets can be delayed en route to their destination. The Net6 device sends false TCP acknowledgements so that the sender continues sending packets. Murli Thirumale, Net6's chief executive officer...

Cisco tightens VoIP security

Like other packet-based applications, voice networks can suffer from denial-of-service attacks, which are caused when a hacker floods a network with packets until the switches and routers directing traffic throughout the network are frozen.

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

The problems of packet loss, delay and jitter are exacerbated when voice traffic intermingles with packets from other applications. When packets arrive at their destination, they can arrive in any order with significant delay.

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.
