Behavior of TCP-Like Elastic Traffic at a Buffered Bottleneck Router

Tags:
switching

Overview A major challenge in traffic modeling and performance analysis for the Transmission Control Protocol (TCP) stems from the fact that the incoming traffic is not independent of the congestion level in the network. This paper investigates a queueing model where the traffic essentially shows ON/OFF characteristics, i.e. the number of active TCP connections of finite (probabilistic) duration varies as described by a stochastic process. The essential behavior of TCP-like flow-control mechanisms is captured in the analytic model by the feature that the packet-rate of active connections can be throttled in order to avoid that the overall packet-stream exceeds the output-bandwidth of the bottleneck router. By appropriate adjustment of the connection duration, the number of packets in the connections remains unaffected.

Breakthrough protocol offers web turbo boost

Sergei Petrov and Tom Crowley, co-founders of Viewbus, claim the 27 year-old transmission control protocol (TCP), which directs packet data across the internet, can no longer cope with today's traffic levels.

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

It is impossible to control the internet in the same way we control the telephone network and so congestion, collisions and traffic jams cause delays, bunching of packets in an unpredictable manner. For non-real time applications such as email and...

UK government warns on critical web vulnerability

The odds against being able to crack the inter-router codes, basically cracking a rotating number from four billion combinations, were previously estimated as being very high - and would take between four and 142 years to execute.

Secure VoIP has arrived

TCP uses packet retransmission, which means that packets can be delayed en route to their destination. For one, they rely on TCP (Transmission Control Protocol), which works well for data applications but not as well for latency-sensitive traffic...

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. An IP packet is formed when a router chops up a stream of digital information into manageable chunks.

Peter Cochrane's Blog: Fat cat telcos are killing the net

Yes, it all works to some degree some of the time but continually increasing the number of VoIP and videoconference calls, radio and TV broadcasts just creates congestion, increased latencies and ultimately one meltdown after another.

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.

IBM Information Server Change Data Capture

In today's fast-paced world, access to real-time data has never been more important. To be successful, organizations need to be able to report and analyze corporate data quickly and easily, regardless of what applications created the data, what platform they're running on, or what database they're stored in.
