Abstract
The method described here provides for high-speed, Quality of Service (QoS) driven, and secure transport of voice, video and data packets for facilitating the convergence of multiple networking facilities into one. The method involves replacing one or more bits in the IP header address fields and replacing them with or adding to them unique virtual connection or virtual circuit (VC) identifiers for node-to-node, that is device-to-device, connectivity as well as for representing values or parameters for packet type, QoS, security, network management and node/link resources. Identifiers for the above parameters are developed and saved at each node as a switching table. The values representing the identifiers from a switching table are used to assign virtual connections as well as control the flows of packets.
