TCP-Aware Packet Marking in Networks With DiffServ Support

Tags:
tcp - ip

Overview In the context of Differentiated Service, the Assured Forwarding class recently proposed by the IETF offers the capabilities of distinguishing two or more classes of packets, based on bit marking in packet headers. Originally, packet marking was intended to be performed according to the aggregate user-profile in the DiffServ model. This paper shows the benefit of an alternative strategy in which packet-marking is based on the states of individual TCP flows. The marking scheme can be implemented either in end systems or ingress routers, where the number of concurrent flows is limited, thus allowing per-flow management of packets. In addition, it can be integrated with a marking scheme that is based on the user-profile.

Ipv6: An acronym to shake the networked world

Therefore routers can process packets faster. For example, if packets are dealt with in various sub networks with different priorities and so the prioritising must be carried along routes that have already been covered.

'Selfish' routers slow the internet

If the routers that direct the packets of data could be programmed with some altruism, the information might be able to reach its destination a little faster while also allowing other packets to move more quickly.

Indian telecoms explosion tempts Cisco

MPLS is a technology that tags IP packets and creates secure tunnels for traffic through the network. The carrier will be using Cisco 12000, 7300 and 7200 series routers and its Catalyst 4500 series switches.

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

The problems of packet loss, delay and jitter are exacerbated when voice traffic intermingles with packets from other applications. When packets arrive at their destination, they can arrive in any order with significant delay.

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.
