UDT: An Application Level Transport Protocol for Grid Computing

Overview As network bandwidth and delays increase, TCP becomes inefficient. These problems are due to slow loss-recovery, a RTT bias inherent in its AIMD congestion-control algorithm, and the bursting data flow caused by its window control. Data-intensive applications over high bandwidth delay product (BDP) networks, such as computational grids, need new transport protocols to support them. To meet this requirement an application-level protocol is built above UDP, called UDP-based Data Transfer protocol, or UDT. UDT has a congestion control mechanism that maintains efficiency, fairness and stability, and its application-level nature enables it to be deployed at the lowest cost, without any changes in the network infrastructure or operating systems.

SDSL pilot promises high-bandwidth data transfer

We hear about the internet enabling ecommerce but I think the bandwidth available to the consumer market is a limiting factor and until we get that bandwidth available I don't think we are going to see a really big take up of ecommerce," said Wright.

Slammer time - SQL worm brings net to its knees over weekend

System administrators who are unable to download the patch should block UDP port 1434, said experts. UDP port 1434 is used by the SQL Server Resolution Service, which provides a way for clients to find a particular instance of SQL Server on a machine.

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?
