TCP - IP White Papers

Performance of TCP Over a Link Using Fair Queueing

Tags:
tcp - ip

Overview Despite its apparent simplicity, buffer dimensioning is not a well understood topic. Until quite recently, a simple rule based on the functioning of TCP Reno, advised a buffer size equal to the Bandwidth Delay Product: the buffer must have enough place to never become idle when a single TCP flow is emitting. Since today's available link capacity is around 10Gb, and the mean delay used for the computation close to 250ms, buffer sizes should be very high (2,5Gb) which cause several problems of feasibility or quality of service.

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

Consequently, VoIP applications buffer packets to allow them to be processed more smoothly. 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...

IBM to sell supercomputing server

Changing the technology saved money but resulted in a six-month project delay, a representative said. That means more high-speed cache memory and communication bandwidth is available for that core. The lab is consuming much of the p5-575 production...

Bog reel: Welsh company puts cables in the sewer

Sewers are built in such a way that the channel is clear enough to allow the effluent to flow freely, so cables must be laid so that they don't hamper this. Using the sewers, organisations can set up their IT and telecoms networks with virtually...

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?
