SYSTEM AND METHOD FOR ROUTING DATA CELLS THROUGH AN ATM ARCHITECTURE USING QUALITY OF SERVICE DATA IN A SERVICE CONTROL POINT
First Claim
1. For use in an asynchronous transfer mode (ATM) network, an ATM switch controller capable of routing a call through said ATM network, comprising:
- a database capable of storing at least one of quality of service (QoS) data and congestion level data received from a plurality of ATM switches in said ATM network; and
a route selection controller capable of receiving a call request from a first of said plurality of ATM switches and selecting a call route connection to a second of said plurality of ATM switches, wherein said second ATM switch adjoins said first ATM switch and said selected call route connection is selected in response to at least one of QoS data and congestion level data of said second ATM switch stored in said database.

Abstract
There is disclosed, for use in an asynchronous transfer mode (ATM) network, an ATM switch controller capable of routing a call through the ATM network. The ATM switch controller comprises: 1) a database capable of storing at least one of quality of service (QoS) data and congestion level data received from a plurality of ATM switches in the ATM network; and 2) a route selection controller capable of receiving a call request from a first of the plurality of ATM switches and selecting a call route connection to a second of the plurality of ATM switches, wherein the second ATM switch adjoins the first ATM switch and the selected call route connection is selected in response to at least one of QoS data and congestion level data of the second ATM switch stored in the database.

17. For use in an asynchronous transfer mode (ATM) switch controller disposed in an ATM network comprising a plurality of ATM switches, a method of routing a call through the ATM network comprising the steps of:
-
receiving at least one of quality of service (QoS) data and congestion level data from the plurality of ATM switches;
storing the received at least one of QoS data and congestion level data in a QoS database;
receiving a call connection request from a requesting ATM switch;
determining an end-user QoS requirement associated with the call connection request;
comparing the end-user QoS requirement with the stored at least one of quality of service (QoS) data and congestion level data associated with at least one ATM switch adjoining the requesting ATM switch; and
selecting a call route connection to the at least one adjoining ATM switch.
