Technical Summary

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

One feasible E2E traffic engineering solution is the use of a Path
Computation Elements (PCE) in a native IP network.  This document
describes various complex scenarios and simulation results when
applying a 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.

Working Group Summary

This document received limited support and no objections to
publication as an Information document within the WG.

Document Quality

This document describes scenarios and a related simulation, and has
input from multiple operators.
