<p>A first Multi Protocol Label Switching (MPLS) enabled Internet Protocol (IP) data network (11) is able to transmit data to a second MPLS enabled IP network (13) via a legacy optical network (12). The simulation/emulation of an MPLS network is performed when a first legacy network element (NE) (14a) receives a connection request (a UNI request) from the MPLS network (11) under a UNI protocol, the UNI request is passed (arrow A) to the TNMS (16), which then sets (arrows B) the required connection across the legacy network (12) via a second edge NE (14b) to an NE of the second IP network (13). Once the connection has been set the TNMS (16) instructs (arrow C) the edge NE (14a) to send a return signal to the requesting network (11) indicating that the connection has been successfully set. Data packets may then be transmitted across the network (11, 12, 13).</p> |
