MPLS - A Foundation for Service Differentiation by the ISP World

Tags:
atm

Overview The IP-over-ATM model allowed many carriers to Multiplex Internet traffic as one of many services carried over an ATM core in a cost effective manner. But soon faster and higher bandwidth ATM switches were outperformed by Internet backbone routers. MultiProtocol Label Switching (MPLS) offers simpler mechanisms for packet-oriented traffic engineering and multiservice functionality with the added benefit of greater scalability. The paper discusses in brief the forces that motivated the development and evolution of different multilayer switching solutions that eventually culminated in the IETF working group's definition of MPLS.

Ipv6: An acronym to shake the networked world

This can be done using MPLS (Multiprotocol Label Switching) or tunnelling. IPv6 will be spread first of all at the edges of the internet, but IPv4 is likely to dominate the backbone for a long time. For example, if packets are dealt with in various...

MPLS: The icing on the networking cake?

An MPLS network will run over whichever mix of networking technologies it faces, including Ethernet, ATM and Synchronous Digital Hierarchy (SDH). There are a whopping 72 MPLS types in development carried out by different organisations.

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 practice, the former involves finding a method...

ITU 03: C&W looks to allowing global QoS

IP VPNs often now take advantage of a technology called MPLS (multiprotocol label switching) for greater flexibility and quality of service (QoS), however QoS can become difficult for carriers to maintain as traffic jumps from one network to...

Indian telecoms explosion tempts Cisco

Bharti Infotel, a subsidiary of Bharti Tele-Ventures, one of four major telecom providers in India, announced on Wednesday that it has chosen Cisco to be the main equipment supplier to build its IP-based multiprotocol label switching (MPLS) network.

Brampton Factor: Network convergence is no simple task

Carriers are naturally resistant to erosion of call prices but they know it is inevitable and are still keen to obtain marginal revenue. But this arises simply because the cost of handling calls is now very low for the carriers.

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.
