Capacity Planning of Survivable MPLS Networks Supporting DiffServ

Tags:
mpls

Overview It is essential for ISPs to offer both performance and survivability guarantees at the IP/MPLS layer. Capacity planning is needed to ensure there will be sufficient resource availability and quality of service under normal circumstances, and during network failures. This paper studies the issue of capacity planning for survivable MPLS networks providing DiffServ EF and BE traffic classes. The goal is to minimize the total link cost, subject to the performance and survivability constraints of both EF and BE classes. The problem is formulated as an optimization problem, where the routes are jointly selected for edge to edge EF and BE user demand pairs, and assign a discrete capacity value for each link.

MPLS: The icing on the networking cake?

There are three main functions of MPLS, quality of service, traffic engineering - which includes a unique ability to re-route traffic very quickly in case of network failure - and enabling virtual private networks (VPNs).

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. European service providers are currently caught...

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

Obviously, no guarantees for call quality can be given but that is not stopping millions of people from using it. In these circumstances, packet loss is inevitable and no service provider can guarantee otherwise.

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.
