    abstract =  {The Path Computation Element Communication Protocol (PCEP) defines the mechanisms for the communication between a client and a PCE, or among PCEs. This document describe the usage of Transport Layer Security (TLS) and the TCP Authentication Option (TCP-AO) to enhance PCEP security, hence the PCEPS acronym proposed for it. The additional security mechanisms are provided by the transport protocol supporting PCEP, and therefore they do not affect its flexibility and extensibility.},
