DEFINITION

Classification: 370/352

Combined circuit switching and packet switching:

(under subclass 351) Subject matter wherein the switching network has both (a) a switch which establishes a path between a source and destination with the path being held for the duration of the communication, and (b) a switch which routes information based on an address associated with the information data in a channel which is only occupied for a duration of the time required to transmit the information data and the associated address.
