MPLS stands for Multiprotocol label switching. It is a one of the techniques for routing network packets. It is protocol-agnostic and speeds up packet forwarding and routing. In a traditional, non-MPLS network, packets are routed at each hop. It is mainly focused on IPv6 and Ipv4. MPLS works only between OSI Layer-2 (Data link Layer) and Layer 3 (Network Layer) and it’s often known as a layer of 2.5 protocol.
