>This document provides a security framework for Multiprotocol Label

>and GMPLS security framework"), but particularly addresses MPLS-TP
>extensions. It starts with a good background on the security reference

>network architectures. It then outlines threats in an MPLS network that
>are either particularly important to MPLS-TP.
>The primary mitigation for threats to the infrastructure is to use some
>form of packet authentication, and this is well covered. It also stresses
>threats and mitigations to using a network management system used to
>provision MPLS-TP network elements. Draft -08 is much improved over -07,
