The Register primer on MPLS IP VPN
Connecting the multisite organisation
Multi-protocol Label Switching (MPLS) based virtual private networks (VPNs) have emerged as an affordable option for connecting medium-sized multi-site organisations.
Very briefly, MPLS allows for much larger packets to be transferred with far less overhead than older standards such as Asynchronous Transfer Mode (ATM) and Frame Relay. It uses labels to define the content of each packet, meaning it can carry a number of different kinds of traffic, voice, data and applications.
VPNs offer secure connections across MPLS. Packets are encrypted as they are passed onto the MPLS infrastructure, and decrypted as they exit, ensuring that confidentiality and privacy are preserved.
That's the barebones: need help wading through this acronym soup? The Register primer on MPLS IP VPN is designed for you, to help to make the most of MPLS IP VPN and ensure you have the proper agreements when choosing a service provider.
Networking techies, this primer is not aimed at you - unless you want some collateral to help you make the business case for upgrading to MPLS.
