MPLS Transport Profile (MPLS-TP) Security Framework
Abstract
This document provides a security framework for the MPLS Transport
Profile (MPLS-TP). MPLS-TP extends MPLS technologies and introduces
new Operations, Administration, and Maintenance (OAM) capabilities, a
transport-oriented path protection mechanism, and strong emphasis on
static provisioning supported by network management systems. This
document addresses the security aspects relevant in the context of
MPLS-TP specifically. It describes potential security threats as
well as mitigation procedures related to MPLS-TP networks and to
MPLS-TP interconnection to other MPLS and GMPLS networks. This
document is built on RFC 5920 ("Security Framework for MPLS and GMPLS
Networks") by providing additional security considerations that are
applicable to the MPLS-TP extensions. All the security
considerations from RFC 5920 are assumed to apply.
This document is a product of a joint Internet Engineering Task Force
(IETF) / International Telecommunication Union Telecommunication
Standardization Sector (ITU-T) effort to include an MPLS Transport
Profile within the IETF MPLS and Pseudowire Emulation Edge-to-Edge
(PWE3) architectures to support the capabilities and functionality of
a packet transport network.
