After successfully completing this course, attendees will:

• List the features, functions and benefits of MPLS
• Identify suitable applications for MPLS
• Describe the underlying concepts of MPLS
• Describe the frame-mode MPLS and cell-mode MPLS
• Describe the concept of MPLS labels, label stack and different label formats
• Describe the label distribution process between LSRs
• Describe the loop detection and prevention mechanisms in MPLS
• Explore the future trends of MPLS

MPLS stands for "Multiprotocol Label Switching". In an MPLS network, incoming packets are assigned a "label" by a "label edge router (LER)". Packets are forwarded along a "label switch path (LSP)" where each "label switch router (LSR)" makes forwarding decisions based solely on the contents of the label. At each hop, the LSR strips off the existing label and applies a new label, which tells the next hop how to forward the packet.

Label Switch Paths (LSPs) are established by network operators for a variety of purposes, such as to guarantee a certain level of performance, to route around network congestion, or to create IP tunnels for network-based virtual private networks. In many ways, LSPs are no different than circuit-switched paths in ATM or Frame Relay networks, except that they are not dependent on a particular Layer 2 technology. An LSP can be established that crosses multiple Layer 2 transports such as ATM, Frame Relay or Ethernet. Thus, one of the true promises of MPLS is the ability to create end-to-end circuits, with specific performance characteristics, across any type of transport medium, eliminating the need for overlay networks or Layer 2 only control mechanismsLabel Switch Paths (LSPs) are established by network operators for a variety of purposes, such as to guarantee a certain level of performance, to route around network congestion, or to create IP tunnels for network-based virtual private networks.

The student will develop an understanding of the MPLS technology, which is quickly becoming the core routing protocol within telecommunications networks.
