Transferring data segments and virtual circuit (VC) information related to the data segments across an Ethernet switch from a first connection terminating at an input port of the switch to a second connection originating at an output port of the switch involves utilizing the VC information at the input port to determine the output port of the data segment, generating tunnel frames that include the identified output port and the VC information as overhead and the data segments as payload, transferring the tunnel frames across the switch from the input port to the output port, generating new headers for the data segments using the VC information that was transferred across the switch in the tunnel frames, and transmitting the data segment, including the new header, on the second connection.
