ABSTRACT:
A computer readable medium stores a program in an ingress capable network device of a network for routing signals through the network. The computer readable includes a receiving code segment for receiving an original signal, which has an embedded destination service address. The computer readable medium also includes a querying code segment for querying a database server to obtain an internal routing address corresponding to the embedded destination service address, and a routing code segment for routing at least a portion of the original signal through the network to an egress capable network device according to the internal routing address. The routed portion of the original signal includes at least the embedded destination service address, which enables the egress capable network device to restore the embedded destination service address and to forward the routed portion of the original signal from the network.
