Resolving Routes for MPLS Traffic Engineering

Overview This paper describes how Multiprotocol Label Switching (MPLS) traffic engineering maps certain data flows to established label switched paths (LSPs) rather than to data links calculated by the IGP to be part of the best(shortest) path. Multiprotocol Label Switching (MPLS) traffic engineering maps certain data flows to established label switched paths (LSPs) rather than to data links calculated by the IGP to be part of the best (shortest) path. Fundamental to this function is the determination of what traffic is to be mapped to an LSP. Traffic is mapped to an LSP at the tunnel's ingress label switching router (LSR) by designating the egress LSR as the next-hop router for certain destination prefixes. It is important to understand that the LSP does not constitute an entire route to a destination. Rather, the LSP is a next-hop segment of the route. This paper assumes that you understand the basics of MPLS and the JUNOS command-line interface.

MPLS: The icing on the networking cake?

Multi protocol label switching, sexily tagged MPLS, is the juvenile standard being developed to give service providers better control over networks. Iain Stevenson, networking analyst at Ovum, put it like this: "MPLS is a mechanism for labelling...

'Selfish' routers slow the internet

According to the paradox, the packets of information would simply hop from one path to another - much like drivers switching lanes in a traffic jam - actually slowing down all the other packets traveling on those pathways.

IP over everything?

The service provider uses Ethernet to transport IP traffic over optical wavelengths, coupled with Multiprotocol Label Switching (MPLS), which it claims guarantees the timely delivery of the packets. In each location, we have an IP VPN router, SDH...

BT to go all IP, promises universal broadband

If the 21st Century Network project, as BT calls it, is a success, the telco will be able to deliver voice and data services over a network supporting Internet Protocol (IP) and Multiprotocol Label Switching (MPLS).

Devil's Advocate: VoIP not for everyone

So while it looks a safe bet to see VoIP as the long-term destination, immediate installations need to be justified on a detailed assessment of costs and benefits. Switching from the public switched network to private data lines is often...

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

The router then places two addresses in the packet's header field - one for the destination, one for the originating device. After looking up the packet's destination in the number's address tables, the router forwards the packet to the next router...

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.
