Abstract

See full text

Communications traffic in a network is addressed. An original signal comprising an embedded destination service address is receiving at an ingress capable network device of the network. A database server is queried to obtain an internal routing address corresponding to the embedded destination service address. A transit signal corresponding to the original signal and including at least the embedded destination service address is routed through the network to an egress capable network device of the network according to the internal routing address. The transit signal enables the egress capable network device to restore the embedded destination service address and to forward the transit signal from the network.
