Using Packet Probes for Available Bandwidth Estimation: A Wireless Testbed Experience

Overview Evaluating available bandwidth estimation methods requires a malleable MAC protocol implementation, precise MAC layer packet timing measurements, and the ability to create control topologies in laboratory setups so that not all nodes are within communication range. To address these challenges, it have exploited IEEE 802.11e-derived features to obtain more control over the MAC layer operation of -the-shelf radios and implemented a measurement-system that uses CPU timestamp counter and radio hardware times-tamps to monitor MAC activity with microsecond resolution. In addition to presenting performance of the available bandwidth estimation method using packet probes, it also discusses solutions and open issues to provide useful information for other testbed cross-layer protocol evaluations, which are likely to face similar challenges.

What are IP VPNs good for?

Infonet is now saying that businesses can buy packet-switched voice over an IP VPN as a standalone product, and then add in other data traffic later on," says Henning Dransfeld, senior analyst for enterprise IP services at Ovum.

Peter Cochrane's Uncommon Sense: Hype and Skype

In addition, Mac users have iChat, which includes voice and video for free. 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.

Warning over "critical" QuickTime hole

The vulnerability affects QuickTime 7.1.3, the latest version of the media player software released in September, on both Apple Mac OS X and Microsoft Windows, according to the Month of the Apple Bugs advisory.

How to baseline power consumption

Overstretched IT departments, beset by demands for accountability from the business, may well decide not to prioritise such baselining activity on energy, preferring instead simply to take a stab at reducing power consumption as best they can.

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.
