System And Method For Automatic Identification Of Bottlenecks In A Network

View page
US Patent:
6457143, Sep 24, 2002
Filed:
Sep 30, 1999
Appl. No.:
09/410244
Inventors:
Po Cheung Yue - Ossining NY
Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
G06F 1100
US Classification:
714 43, 709223
Abstract:
A system and method for providing automated bottleneck identification in networks and networked application environments by processing using end-to-end quality of service measurements in combination with knowledge of internal resource dependency information generated by a network administrator. In one aspect, a method for identifying bottleneck resources in a network having a plurality of resources comprises the steps of: specifying a plurality of probe transactions in the network; generating resource dependency information representing dependent resources for each of the probe transactions; executing the probe transactions; measuring end-to-end quality of service data resulting from the executing of the probe transactions; and processing the resource dependency information and measured end-to-end quality of service data to identify bottleneck resources in the network. The system and method eliminate the need for obtaining and processing detailed measurements and/or estimates of parameters or data at the per resource level to identify bottlenecks.

Performance Improvement Tool For Rule Based Expert Systems

US Patent:
5129043, Jul 7, 1992
Filed:
Aug 14, 1989
Appl. No.:
7/393526
Inventors:
Po C. Yue - Ossining NY
Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
G06F 1516
US Classification:
395 51
Abstract:
A monitoring system monitors an expert system application while such application executes for a period of time. The monitoring system records selected performance data relative to the operating efficiency of the expert system, and writes such data into a database for later use. After a test run of the expert system is completed, the monitoring system can select a small number of candidate rules for revision by a user, and display data to the user which allows the user to determine what types of changes need to be made to the candidate rules and to the working memory data organization.

System And Method For Automated Problem Isolation In Systems With Measurements Structured As A Multidimensional Database

View page
US Patent:
6330564, Dec 11, 2001
Filed:
Feb 10, 1999
Appl. No.:
9/247239
Inventors:
Joseph L. Hellerstein - Ossining NY
Po Chang Yue - Ossining NY
Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
G06F 1700
G06F 700
US Classification:
707101
Abstract:
A system and method are described for automating navigations in systems with measurement data that are structured as a multidimensional database (MDDB). The navigation includes an Automated Navigation Engine that uses external representations of a dimension selection function and a cube selection function to guide MDDB navigations. The method consists of the steps: (1) select the MDDB dimension that has the largest dimension selection score; (2) if this score is too small, terminate the method; (3) otherwise, select the cube with the largest cube selection score. These steps are performed repeatedly until (2) applies. Navigations can be performed for data mining, problem isolation, trending analysis, etc.
