It does not account for terminal disclaimers, term adjustments, failure to pay maintenance fees, or other factors which might affect the term of a patent.AbstractA method of processing ATM service requests to a SONET network, wherein the customer requesting the service has specified certain ATM quality of service parameters, by mapping measured SONET performance parameters to predicted ATM quality of service parameters for an end-to-end path or connection through the SONET network. The system compares the predicted ATM quality of service parameters with the specified ATM quality of service parameters. Whenever at least one of the expected ATM quality of service parameters is worse than the corresponding specified ATM quality of service parameter, the system rejects the path or connection. The system may then either test an alternate path through the network or not provide the service. | InventorAssigneeApplicationNo. 730838 filed on 10/17/1996US Classes:370/230, Control of data admission to the network370/252Determination of communication parametersField of Search370/230, Control of data admission to the network370/234, Measurement of the average data flow rate370/231, End-to-end flow control370/232, Based on data flow rate measurement370/238, Least cost or minimum delay routing370/252, Determination of communication parameters370/253, Measurement of flow rate of messages having an address header370/255, Using a particular learning algorithm or technique370/254, NETWORK CONFIGURATION DETERMINATION370/228, Spare channel370/400Having a plurality of nodes performing distributed switchingExaminersPrimary: Nguyen, ChauUS Patent References5233604, Methods and apparatus for optimum path selection in packet transmission networksIssued on: 08/03/1993 Inventor: Ahmadi, et al.5335222, Traffic control system for asynchronous transfer mode exchange Issued on: 08/02/1994 Inventor: Kamoi, et al.5357507, Fast connection admission control for ATM networks Issued on: 10/18/1994 Inventor: Hughes, et al.5548581, System and method for making connection acceptance/rejection decisions in a communication system Issued on: 08/20/1996 Inventor: Makrucki5581544, Method and apparatus for evaluating QOS in ATM multiplexing apparatus in which priority control is performed and for controlling call admissions and optimizing priority control on the basis of the evaluation Issued on: 12/03/1996 Inventor: Hamada, et al.5677907Method of calculating cell loss ratio and call accept controller using the same method Issued on: 10/14/1997 Inventor: Hamada, et al.
