Methods and apparatus for establishing connections between network nodes across an MPLS domain. A data receive node transmits to a data transmit node the service label that the data receive node expects to receive embedded in packets originating from the data transmit node. Any packet that has this service label by the data receive node will therefore be treated and considered by this data receive node as originating from the data transmit node.

ATM over MPLS connection establishment mechanism

A method of creating/terminating a connection associated with an end-to-end path defined through a communications network. According to the invention, cross-connection download/undownload processes in each intermediate node of the end-to-end path are triggered substantially in parallel. A confirmation message indicative of successful completion of respective download/undownload processes in each intermediate node is subsequently propagated to an end-node of the path.
