MPLS – Multi Protocol Label Switching
(MPLS) is a widely used technology since the past decade. At first it was being used for fast switching of packets but due to its scalability and resiliency capabilities soon it became the most popular and vastly used technology across the networks. It simplifies the process of routing the packets through the network by labeling the packets, this leads to fast packet forwarding as the packet itself does not need to be examined and the routing decisions can be made based on the labels itself. The feature of traffic management and the capability to support multiple service models makes it more appealing to the ISPs.
