IETF Multiprotocol Label Switching (MPLS) Architecture
François Le Faucheur · 2002
This paper presents the concepts of the multiprotocol label switching (MPLS) technology currently under standardisation by the Internet Engineering Task Force (IETF). MPLS can be used for transport of any level 3 protocol over any level 2 technology so that one of its applications is integrated transport of IP over ATM for next-generation Internet and intranets. The paper is an excerpt from a working document of the IETF MPLS working group titled "Multiprotocol Label Switching Architecture".
