Abstract

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

One feasible E2E traffic-engineering solution is the addition ofcentral control in a native IP network. This document describesvarious complex scenarios and simulation results when applying thePath Computation Element (PCE) in a native IP network. This solution,referred to as Centralized Control Dynamic Routing (CCDR), integratesthe advantage of using distributed protocols and the power of acentralized control technology, providing traffic engineering fornative IP networks in a manner that applies equally to intra- andinter-domain scenarios.
