There are different routers used in MPL Technology. These labels are router specific and local significant to that router.įirstly, I want to talk about Router terms used in this technology. This new protocol is using Labels for routing decisions. But changing all the existing routing protocols was very difficult, so IETF has chosen developing a new protocol. This development could be done with existing routing protocols. To solve all these problems IETF developed MPLS in 1997. In addition to these negative facts, there were some other problems about ATM technology, while working together with Ethernet and Frame Relay. If you would like to learn more about MPLS, you can follow the lessons of Nokia MPLS Training. In brief, MPLS Networking is combining the beneficial parts of both Layer 2 and Layer 3 of OSI reference model. Beside that it brings the speed of OSI layer 2 switching. Here Multi Protocol Label Switching brings also CEF and this bypass the slow part of this layer 3 decisions. The existing routing protocols are looking to the routing table for forwarding decision on all nodes and this was overloading the routers beside causing a lot of time lose. Over time, users in networks have increased and this big traffic has brought high bandwidth and forwarding speed need. It is the abbreviation of Multi Protocol Label Switching. In this lesson, we will focus MPLS in Networking and we will learn the answer of what is MPLS? So, What is MPLS? MPLS is a Packet-Forwarding technology which uses MPLS Labels for data forwarding decisions.
