Abstract
A method of address resolution for the transfer of voice and voice data calls through multiple domains in a broadband data network is described. The implementation of broadband data networks as transport backbones for voice and voice data calls requires address resolution to determine the destination node for each call. Because of the projected frequency at which new access peripherals will be added to such broadband data networks, manual maintenance of translation tables is impractical. The invention therefore provides an automated method for address resolution which permits voice interface control units associated with the broadband data network nodes to automatically maintain the required translation tables. Next-hop resolution routing tables may be maintained at every node or only at nodes designated as signaling gateways between broadband data network domains. If the broadband data network is an ATM network, switched virtual circuits are set up in reverse from ATM destination nodes in order to reduce call admission and setup time. The advantage is automated maintenance of translation tables which may be tailored to meet the operating policy of network managers that control res…
