MPLS Concepts and Applications

опис

Multiprotocol Label Switching (MPLS) is a standards-approved technology for speeding up network traffic flow and making it easier to manage.
MPLS involves setting up a specific path for a given sequence of packets, identified by a label put in each packet, thus saving the time needed for a router to look up the address to the next node to forward the packet to. MPLS is called multiprotocol because it works with the Internet Protocol (IP), Asynchronous Transport Mode (ATM), and Frame Relay network protocols.

With reference to the standard model for a network (the Open Systems Interconnection, or OSI model), MPLS allows most packets to be forwarded at the layer 2 (switching) level rather than at the layer 3 (routing) level. In addition to moving traffic faster overall, MPLS makes it easy to manage a network for quality of service (QoS).

This seminar is intended to be a small reference guide for the MPLS protocol, explaining its basic concepts as well as its basic applications, such as MPLS VPN's, Traffic Engineering with MPLS, QoS with MPLS and GMPLS
