What is MPLS?

Multiprotocol Label Switching is a protocol for speeding up and shaping network traffic flow. It delivers an affordable, reliable and highly secure, private network solution to optimise Wide Area Networks (WAN) and unify communications across geographically diverse office locations.

MPLS will enable customers to easily connect and communicate efficiently between each site as part of a single network.


How does MPLS work?

Essentially, MPLS is a methodology for delivering “packets” of information around the internet. The way this works is to assign a unique identifier (also known as a forwarding equivalence class, or “the label”) to the packets of data that make up each transfer running through the network.

The purpose of this is to make the transfer of data throughout the routers of the network more efficient. As each router in the network has a table indicating how to handle packets of a specific FEC type, each router does not therefore need to perform a header or packet analysis expediting the transfer of each packet from its destination to its source.

This logic gives the MPLS network the ability to handle packets in a consistent fashion. Packets carrying real-time traffic, such as voice or video, can easily be mapped to low-latency routes across the network.

The key architectural point with all this is that the labels provide a way to attach additional information to each packet — information that is above and beyond what was previously available, providing the end user with a more efficient and streamlined service.


Benefits of MPLS

Multiprotocol Label Switching delivers multiple levels of QoS (Quality of Service) as standard, to provide optimised network performance, so you can be sure you are always getting the best from your business connectivity as we seamlessly prioritise critical data. MPLS also reduces the amount of manual intervention by your network provider to create a WAN (Wide Area Network), thus reducing the likelihood of human error.

MPLS delivers a cost-effective solution to meet business critical WAN requirements, enabling support for IP telephony, video conferencing, Unified Communications (UC), software applications supplied ‘as a service’ (SaaS) and cloud services.
