“…The existing solutions described in [3,4] require either having an IP/MPLS Router on top of the ATM switches, or establishing a tunnel across the ATM backbone. A more appropriate and general solution would be that integrating both MPLS and ATM technologies.…”

Abstract. Multiprotocol Label Switching (MPLS) is an advanced forwarding scheme, which allows the network to achieve the benefits provided by Traffic Engineering (TE) techniques. The establishment of an end-to-end LSP between two IP/MPLS networks interconnected through an ATM backbone is still an open issue. This paper focuses in an MPLS-ATM environment, and addresses the problem of providing a fast LSP establishment, with certain QoS (Bandwidth guarantee), between two MPLS subnetworks interconnected through an ATM backbone. The Private Network to network Interface (PNNI) is used in ATM backbone as a routing and signaling protocol. In order to achieve the paper objectives, new PNNI elements are defined and evaluated.

“…In this paper we suggest adding a new Generic Identifier Information Element in the SETUP message with an Identifier related standard/application field of value (0x06) corresponding to MPLS, and an identifier type of value (0x02) corresponding to Resource. In this case the Identifier is the MPLS VCID used in [12] to solve the problem of using the VPI/VCI field as MPLS label in SVC ATM networks. This identifier is used to identify an ATM VC in an LDP mapping message and is transported end to end between ATM LSR to achieve the same value at both ends.…”

Abstract-Multiprotocol Label Switching (MPLS) is an advanced forwarding scheme, which allows the network to achieve the Traffic Engineering (TE) objectives. When two or more MPLS nodes are connected via an ATM backbone merely composed of ATM switches, it is necessary to add some mechanisms to allow the label distribution and allocation between both nodes. In this paper a solution is proposed to integrate ATM and MPLS, so that the ATM backbone will be seen as a unique MPLS node from the MPLS domain and as a consequence of that the end-to-end LSP establishment can be carried out.
