Pacing to Improve SACK TCP Resilience

Tags:
tcp - ip

Overview The Transmission Control Protocol (TCP) was designed to provide a reliable end-to-end connection. The most up-to-date TCP version, SACK TCP, was designed to be capable of surviving multiple segment loss. SACK TCP tends to send out segments in clusters and congest bottleneck routers, which could potentially degrade SACK TCP performance significantly. This paper presents a-min paced SACK TCP that spreads out outstanding segments and reduces the number of segments queued at bottleneck routers. It also demonstrates formally that a-min paced SACK TCP is "Correct" in the sense that all states are bounded and the desired final state is always reachable from the initial state.

Router holes 'threaten the internet'

The ensuing avalanche of data took down the router and disrupted major segments of the net, causing an outage that in some places lasted as long as two hours. There'll only be an improvement if the majority of routers use a secure protocol - but...

Cisco glitch could allow hackers into Windows servers

An exploit for the vulnerability is not known to be circulating, and ACS servers are usually deployed on network segments with limited physical access. A potentially critical vulnerability has been found in Cisco Systems' Secure Access Control...

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

Routers ping each other, to see which pathway is congested, completely blocked or relatively open. Both can tell routers what priority it has over other applications. The LAN cabling and routers may need upgrading, new handsets will need to be...

Cracked: The Great Firewall of China

The researchers found it was possible to circumvent the Chinese intrusion detection systems (IDS) by ignoring the forged TCP resets injected by the Chinese routers, which would normally force the endpoints to abandon the connection.

Leader: Is BT-FON deal a real mesh?

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.
