Description
Summary:MPLS was originally designed to make IP routers are as fast as ATM switches for handling traffic. Just as in any other technology. MPLS has a specialized terminology all its own. An MPLS domain is the collection of routers running MPLS under the control of a single Administrator. An LSP (label-switched path) is a one-way (unidirectional) Flow of traffic, carrying packets from beginning to end. Packets must enterThe LSP at the beginning (ingress) of the path, and can only exit the LSP At the end (egress). Packets cannot be injected into an LSP at an intermediate hop. Generally, an LSP remains within a single MPLS domain. That is, the Entrance and exit of the LSP, and all routers in between, are ultimately in control of the same administrative authority. This ensures that MPLS LSP Traffic engineering is not done haphazardly or at cross purposes but is implemented in a coordinated fashion.
