G06F011/00

US Classification:

714 48, 714 4, 709223

Abstract:

A system and method for determining a cause of a network problem between a first endpoint and a second endpoint, is disclosed. Generally, a first computer is utilized comprising a transceiver, software stored within the first computer defining functions to be performed, and a processor configured by the software to perform the steps of: associating a received error message with an error identification number; and associating the error identification number with a root cause proximity value, wherein the root cause proximity value represents a relationship between the received error message and an actual cause of the network problem.

US Classification:

709/223000

Abstract:

System and method for managing notification messages related to statuses, abnormalities and exceptions within a communication network. Generally, a computer is utilized comprising software stored within the computer defining functions to be performed, and a processor configured by the software to perform the steps of: receiving a notification message; indexing a notification message to a status within a communication network; retrieving rules for processing the notification message; determining one or more pre-defined managed correlation orbs in which to store the notification message; retrieving both a notification message textual definition and topographical data, wherein the topographical data is used to create a graphical diagram of the overall communication network and affected segment; and transmitting the notification message textual definition and graphical diagrams to operations personnel for any required further action.

US Classification:

709/224000

Abstract:

A system and method for processing an unsolicited error message. is disclosed. Generally, a first computer is utilized comprising a transceiver, software stored within the first computer defining functions to be performed, and a processor configured by the software to perform the steps of: parsing an error message to determine an identification number that represents a most significant meaning of the error message; and, determining a description of the error message after parsing. The identification number is determined by dividing the error message into an identifier portion and a series of properties portion, wherein the identifier portion provides a general description of a cause of the error message, and the series of properties portion provides specific attributes of the error message. The identification number is then processed in accordance rules provided to the system for processing the error message.

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G06F 1540

US Classification:

395616

Abstract:

A new system and method allows a Manager in a Simple Network Management Protocol (SNMP) environment to gather updates from its Agents. The system and method comprise the unique provision of an index which is used in each of the Agent's tables for indicating the various revisions thereof. The index lexicographically increases with each revision to the table. The Manager maintains a record of the index of the data which it has received from its Agents, requesting only that data having a lexicographically larger indexing. Further, the index is used in related tables so that the tables will be kept in "sync" in that the Manager will know whether it has the latest updates so that an accurate picture may be portrayed.

International Classification:

US Classification:

395600

Abstract:

A new system and method allow one or more Managers in a network to retrieve from an Agent problem determination data relating to the Agent's Components. The system and method of the present invention allow the Manager to use standard mechanisms to retrieve and display the Agent's problem determination data. A generic collection subsystem created by the Agent acts as an interface for the Agent to the Components for collecting and organizing the problem determination data received from the Components. The collection subsystem receives and stores problem determination data from each of the components in tables which are organized based upon the type of problem determination data. Within each table, the data objects may be stored chronologically, for example. The collection subsystem responds to all requests from the Agent for stored problem determination data. The requests may specify particular parameters such as the type of problem and time it occurred.

International Classification:

G06F 1500

US Classification:

39520006

Abstract:

A system and method for recording accounting times by an Agent in a network and retrieving the accounting times by the network Manager. Three types of data objects in each of the Agent's stored records are provided. Record Number is the sequence number of the record in the file. Recording time is an indication of the time the record was stored in the file since a certain point in time, such as after the Agent's clock began running. Record Type is the particular type of record stored. The Record Type can either be DATA representing normal accounting data or TIME representing time data used for correlating the Manager's and the Agent's time-keeping. Upon receipt of an accounting data record of type DATA, the manager uses the record's Recording time to help determine the point of time accorded to that event. The Manager then uses the previous record of type TIME to adjust the Recording time of the received accounting data record relative to the Manager's precise calendar time.

International Classification:

G06F 1730

US Classification:

709224

Abstract:

A method of data retrieval reduces the number of Instrumentation message flows in a Simple Network Management Protocol (SNMP) device. The method uses "look-ahead" algorithms whereby data items which have not yet been requested by the Agent (but are expected to be) are retrieved from Instrumentation. The method comprises the step of retrieving from the Instrumentation an entire row of data from an SNMP table whenever a GetRequest or GetNextRequest Protocol Data Unit (PDU) is issued by the Manager to the Agent. A SubAgent saves this row in anticipation of a subsequent request for another column in this same row thereby eliminating the need for further Instrumentation message flows for further data retrieval from this row. Whenever a new GetRequest is issued by the Manager, a new set of data is retrieved from the Instrumentation. The method further comprises the step of retrieving the next subsequent data item in response to a GetNextRequest against the last row in a given column thereby eliminating the need for a second message exchange at an "end of column" condition.
