An MPLS (Multi-Protocol Label Switching) network is one in which many devices are connected to each other through a master system that receives data from each individual device and relays it to any other device within the network. MPLS networks differ from traditional networks because they connect a large number of devices across long distances by tunneling through the Internet.
How MPLS Networks Work
An MPLS network is a cloud-like system of computers and other devices that all communicate with each other by assigning labels to data packets so that they can be forwarded from one device to another. For example, if Device A wishes to send a data packet to Device E, Device A will insert a header in the data packet with a label stack that contains information about the data packet, where it came from, and where it is going. Device A will then send the data packet to Device B, Device B will send the data packet to Device C, Device C will send the data packet to Device D, and Device D will send the data packet to Device E. Each device strips away past labels and adds new ones in order to keep forwarding the data packet to where it needs to go.
Applications
MPLS networks are generally used for communication and data trafficking purposes. Most large companies have representatives in many different locations. Each of these representatives must be able to communicate with the company’s headquarters and regional offices. MPLS networks allow them to do this by forwarding data packets to each representative on the way to the company’s headquarters.
Advantages
MPLS networks have several advantages that other data transport solutions do not. They connect all devices within the network to each other without using cables, access points, or other tethering equipment. MPLS networks are publicly available to anyone who has access to the Internet, but security protocols allow the network to handle all data packets privately and deny access to all other users. MPLS networks provide the accessibility of point-to-point connections to all devices within the network without requiring the user to setup each connection manually.
