RFC 5394 Policy - Enabled Path Computation
نویسنده
چکیده
The Path Computation Element (PCE) architecture introduces the concept of policy in the context of path computation. This document provides additional details on policy within the PCE architecture and also provides context for the support of PCE Policy. This document introduces the use of the Policy Core Information Model (PCIM) as a framework for supporting path computation policy. This document also provides representative scenarios for the support of PCE Policy. Bryskin, et al. Informational [Page 1] RFC 5394 Policy-Enabled Path Computation December 2008

RFC 5468 Analysis of Inter - Domain Path Computation
This document presents a performance comparison between the perdomain path computation method and the Path Computation Element (PCE) Architecture-based Backward Recursive Path Computation (BRPC) procedure. Metrics to capture the significant performance aspects are identified, and detailed simulations are carried out on realistic scenarios. A performance analysis for each of the path computation...
متن کاملConveying Vendor-Specific Constraints in the Path Computation Element Communication Protocol
The Path Computation Element Communication Protocol (PCEP) is used to convey path computation requests and responses both between Path Computation Clients (PCCs) and Path Computation Elements (PCEs) and between cooperating PCEs. In PCEP, the path computation requests carry details of the constraints and objective functions that the PCC wishes the PCE to apply in its computation. This document d...
متن کاملUse of the Synchronization VECtor (SVEC) List for Synchronized Dependent Path Computations
A Path Computation Element (PCE) may be required to perform dependent path computations. Dependent path computations are requests that need to be synchronized in order to meet specific objectives. An example of a dependent request would be a PCE computing a set of services that are required to be diverse (disjointed) from each other. When a PCE computes sets of dependent path computation reques...
متن کاملInter-AS Requirements for the Path Computation Element Communication Protocol (PCECP)
Multiprotocol Label Switching Traffic Engineered (MPLS TE) Label Switched Paths (LSPs) may be established wholly within an Autonomous System (AS) or may cross AS boundaries. The Path Computation Element (PCE) is a component that is capable of computing constrained paths for (G)MPLS TE LSPs. The PCE Communication Protocol (PCECP) is defined to allow communication between Path Computation Clients...
