MPLS TE Theory
This section introduces you to the theoretical nuances in the implementation of MPLS TE. The primary topics covered will be the components of MPLS TE as well as RSVP and its function in the implementation of MPLS TE.
MPLS TE Overview
In a traditional IP forwarding paradigm, packets are forwarded on a per-hop basis where a route lookup is performed on each router from source to destination. As cited earlier, the destination-based forwarding paradigm leads to suboptimal use of available bandwidth between a pair of routers in the service provider network. Predominantly, the suboptimal paths are under-utilized in IP networks. To avoid packet drops due to inefficient use of available bandwidth and to provide better performance, TE ...
