PCEPS: Usage of TLS to Provide a Secure Transport for the
Path Computation Element Communication Protocol (PCEP)
Abstract
The Path Computation Element Communication Protocol (PCEP) defines
the mechanisms for the communication between a Path Computation
Client (PCC) and a Path Computation Element (PCE), or among PCEs.
This document describes PCEPS -- the usage of Transport Layer
Security (TLS) to provide a secure transport for PCEP. The
additional security mechanisms are provided by the transport protocol
supporting PCEP; therefore, they do not affect the flexibility and
extensibility of PCEP.
This document updates RFC 5440 in regards to the PCEP initialization
phase procedures.
