Atm network externally controlled for network resource reservation of end-to-end switched virtual connection

Abstract From the Canadian patent

In an ATM network, a database is provided in a network controller for holding data pertaining to network topology and remaining network resource. The controller has a supervisory circuit that constantly monitors communication links between ATM switches. Route decision and resource reservation logic circuitry updates the database if a network failure condition is detected by the supervisory circuit. The logic circuitry also receives from a source, terminal, a reservation request indicating a reservation of an end-to-end network resource between a scheduled start time and a scheduled end time, and makes a search through the database to reserve the network resource in the database if the …
