Abstract
A first Multi Protocol Label Switching (MPLS) Internet Protocol (IP) data network transmits data to a second MPLS IP network via a legacy network, which would not otherwise be able to handle the required user network interface (UNI) protocol by configuring the legacy network and its network management system (TNMS) so that they emulate an MPLS network. When a first network element (NE) receives a connection (UNI) request from the MPLS network under a UNI protocol, the UNI request is passed to the TNMS, which then sets the required connection across the legacy network via a second edge NE to an NE of the second network. Once the connection has been set, the TNMS instructs the edge NE to send a return signal to the requesting network indicating that the connection has been successfully set. Data packets may then be transmitted across the network.
