MPLS is a packet-forwarding technology that uses labels to make data forwarding decisions. MPLS also provides beneficial applications, such as Quality of Service (QoS) and Virtual Private Networking (VPN).
Designed for dependable and predictable performance, MPLS routing is done via a proprietary tagging protocol. Because the protocol is unique to MPLS networks, they offer greater security than a simple Internet connection that sets up routing on the fly.
To put it simply, MPLS service works like this: a label edge router connects you to the network, encapsulates your packets and adds an MPLS label to them. Each label defines a specific class that determines where each of your packets should be sent. As your packets go across the network, label switching routers use the labels that were added to your packets to determine how they should be routed. Once your packet reaches its destination, the label is removed by the label edge router and the packet goes on its way intact, looking exactly as it did upon entering.
The labeling system offers a number of significant advantages. To start, because the router does not need to look at the internals of the packet, only the label that indentifies the source, destination and Class of Service (CoS), the time it takes for your packets to traverse the network is decreased dramatically. Moreover, because your MPLS network does not traverse public networks, it’s unlikely any intruder would be able to gain access. Even if they did, they would have no knowledge of the labels used on your particular network, making it hard for them to crack. That being said, if security is your top priority, you have the ability to encrypt your packets for added security. In addition to improved security, MPLS networks offer performance guarantees for packet loss, latency, jitter and bandwidth, making it a popular option for essential business applications, such as web and audio conferencing.
Many businesses today have one or more locations that need to be tied together with data, voice and/or video services. Whether these locations are satellite offices, factories, warehouses, remote data centers, etc, MPLS serves as a simple, cost-effective way of linking them together. If you’re interested in an MPLS solution for your business, give one of our representatives a call today. We work with the leading providers of MPLS services to find you the service that best fits your unique needs and budget.
