Requirements for providing the End-to-End (E2E) performance assurance
are emerging within the service provider networks. While there are
various technology solutions, there is no single solution that can
fulfill these requirements for a native IP network. In particular,
there is a need for a universal E2E solution that can cover both
intra- and inter-domain scenarios.

One feasible E2E traffic-engineering solution is the addition of
central control in a native IP network. This document describes
various complex scenarios and simulation results when applying the
Path Computation Element (PCE) in a native IP network. This solution,
referred to as Centralized Control Dynamic Routing (CCDR), integrates
the advantage of using distributed protocols and the power of a
centralized control technology, providing traffic engineering for
native IP networks in a manner that applies equally to intra- and
inter-domain scenarios.

This document is a product of the Traffic Engineering Architecture and Signaling Working Group of the IETF.
