seems like a good time to learn how the technology works‚ how it can be deployed‚ and what issues still need to be addressed. MPLS operates at an OSI Model layer that is generally considered to lie between traditional definitions of Layer 2 (data link layer) and Layer 3 (network layer)‚ and thus is often referred to as a "Layer 2.5" protocol. It was designed to provide a unified data-carrying service for both circuit-based clients and packet-switching clients which provide a datagram service model

delivery errors. There is a unit known as the brouter that some layers contain which performs as a router‚ and a bridge. The routers and switches function on layers two‚ three and four. These layers are the Data Link Layer‚ Network Layer‚ and Transport Layer. The Data Link Layer offers the function to move data between networks and make corrections to errors that could possibly occur during the Physical Layer. This layer was meant for point-to-point and point-to-multipoint media characteristics

When a packetarrives at one port‚ it is copied to the other ports so that all segments of the LAN can see all packets. Switch A network switch is a computer networking device that links network segments or network devices. The term commonly refers to a multi-port network bridge that processes and routes data at the data link layer (layer 2) of the OSI model. Switches that additionally process data at the network layer (layer 3) and above are often called layer-3 switches or multilayer switches. Router

How do local area networks (LANs) differ from metropolitan area networks (MANs)‚ wide area networks (WANs)‚ and backbone networks (BNs)? Most LAN’s are connected to (BNs) backbone networks that connect multiple LAN’s‚ BN’s‚ MAN’s and WAN’s and can range in size and distance from several hundreds of feet to miles and can have data transmission speed ranging
