Inline Bandwidth Measurements: Implementation Difficulties and Their Solutions

Tags:
bandwidth issues

Overview This paper has proposed the concept of inline network measurement, which involves the concept of "Plugging" an active bandwidth measurement into an active TCP connection. Mechanisms using this method have the advantage of requiring no extra traffic for measuring available bandwidth, whereas other active measurement tools cannot fundamentally avoid adding probing traffic onto the network. However, when the inline network measurement algorithms are implemented in general-purpose computers, some problems arise, such as the clock resolution of the kernel system, Interrupt Coalescence (IC) deployed in network interface cards, and the behavior of TCP receiver.

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

It has been widely proven that VOIP and VCOIP can be engineered over private intranets where the bandwidth and the collisions (traffic jams) can be controlled. Instead of a known and dedicated connection, each packet may arrive by a vastly...

IP over everything?

In practice, the former involves finding a method of utilising traditional SDH infrastructure to transport IP using time-honoured protocols such as ATM and Frame Relay. We can offer more bandwidth for less money because our operating expenditures...

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.
