TCP flaws may lead to DoS attacks, say researchers
News Two researchers in Sweden have found multiple flaws in the TCP stack that could lead to massive denial-of-service attacks if exploited. The TCP stack defines a set of rules by which a computer can communicate over any network.

Improve TCP/IP performance in W2K registry
News Windows 2000 Server's TCP/IP Properties Sheet is a little deceptive in giving the impression that basic information, such as an IP address, subnet mask, default gateway, or DNS server, is all that's required to create connections.

TCP Performance Re-Visited
White Papers Detailed measurements and analyses for the Linux-2.4 TCP stack on current adapters and processors are presented. The impact of CPU scaling and memory bus loading on TCP performance is also described. As CPU speeds outstrip I/O and memory speeds...

TCP Over GPRS: The Effect of Preemption
White Papers The results indicate that TCP performance is degraded more than necessary, as buffered data is flushed immediately when the GPRS traffic is preempted. GPRS extends the widely deployed GSM with a more efficient wireless Internet access.

TCP Testing - Preventing Global Internet Warming
White Papers Do the new TCP congestion control algorithms and other changes have unfairness that could lead to congestion collapse? Testing multiple flows using applications (rsync and ftp) shows some unfairness exists when the bottleneck queue is large; but...

TCP Offload Through Connection Handoff
White Papers Using this interface, the operating system can offload a subset of TCP connections in the system to the network interface, while the remaining connections are processed on the host CPU. However, full TCP offloading may degrade system performance...
