What is MPLS?
Multi Protocol Label Switching provides networks with a more efficient way to manage applications and move information between locations. With the convergence of voice, video and data applications, business networks face increasing traffic demands. MPLS enables class of service (CoS) tagging and prioritization of network traffic, so administrators may specify which applications should move across the network ahead of others. This function makes an MPLS network especially important to firms that need to ensure the performance of low-latency applications such as VoIP and their other business-critical functions. MPLS carriers differ on the number of classes of service they offer and in how these CoS tiers are priced. sourced from Wikipedia I haven’t been able to get ADSL on my line before as my house is too far from the exchange to support it. Will I be able to get a VPN service? Unfortunately not. If your line can not support at least regular ADSL, it won’t be able to host a VPN service.

This process is called hop-by-hop destination-based routing. The route that packets take is based solely on the destination unicast address. Layer 3 routing protocols do not traditionally have any interaction with Layer 2 network characteristics, making the implementation of Quality of Service (QOS) and loading features difficult. Multiprotocol Label Switching (MPLS) is a vendor-independent protocol (based on Cisco’s tag-switching protocol) that applies labels to packets providing QOS and advance route selection functions. This week’s newsletter introduces MPLS concepts. There are several terms used in MPLS implementations. Label Header applied to a packet by an edge label switch router (edge LSR) and used by label switch routers (LSR) to forward packets. Label forwarding information base (LFIB)
MPLS refers to the technological operation that is more properly known as multi-protocol label switching. Essentially, MPLS is an operating scheme that is used to speed up the flow of traffic on a network by making better use of available network paths. The main thrust of the idea is to define or designate the proper path for each function so that the opportunity for bottlenecks within the network are minimized. The concept of MPLS was the brainchild of the Internet Engineering Task Force, or IETF. As the need for handling more traffic on networks connected to the Internet became apparent, the concept of establishing labels in packets that would control the flow and destination of data was understood to be a solution to the issue. MPLS made good use of the existing technology and has continued to be refined as use of the World Wide Web has continued to grow. MPLS plays a major role in keeping the networks of big businesses running smoothly today. The labeling process involves setting t
BT MPLS (Multi-Protocol Label Switching) is a private IP VPN, combining the flexible any-to-any communication found on PSTN or Internet with the reliability, quality and security delivered via private line, frame relay or ATM services. It provides differentiated performance levels and prioritisation of delay and non-delay sensitive traffic as well as voice and multimedia applications on a single network.
