Security Framework for MPLS and GMPLS Networks
Abstract
This document provides a security framework for Multiprotocol Label
Switching (MPLS) and Generalized Multiprotocol Label Switching
(GMPLS) Networks. This document addresses the security aspects that
are relevant in the context of MPLS and GMPLS. It describes the
security threats, the related defensive techniques, and the
mechanisms for detection and reporting. This document emphasizes
RSVP-TE and LDP security considerations, as well as inter-AS and
inter-provider security considerations for building and maintaining
MPLS and GMPLS networks across different domains or different
Service Providers.
