Estimating the term…
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.
For use in a Manager of a network conforming to the Simple Network Management Protocol (SNMP) comprising at least one Agent, said Agent maintaining at least one table, each table comprising a plurality of individual records defining one or more individual managed objects, each individual record having a unique index assigned thereto, a method of monitoring said table comprising the steps of:
For use in a network conforming to the Simple Network Management Protocol (SNMP) comprising at least one Agent, said Agent maintaining at least one table, each table comprising a plurality of individual records defining one or more individual managed objects, each individual record having a unique index assigned thereto, a Manager for monitoring said table comprising:
A network conforming to the Simple Network Management Protocol (SNMP) comprising at least one Agent, said Agent maintaining at least one table, each table comprising a plurality of individual records defining one or more individual managed objects, each individual record having a unique index assigned thereto, a Manager for monitoring said table comprising means for requesting from said Agent, from at least one table, all of said plurality of said individual records for said managed objects which said Manager wishes to monitor, means for receiving from said Agent said requested individual records for said managed objects, means for inspecting each individual record of said plurality of individual records received from said Agent to determine said unique index of each individual record, means for maintaining a record of said index of a most recently received record for each managed object, means for periodically requesting from said Agent, from said at least one table, a next record defining a changed object representing an update to said most recently received record for each managed object as indicated by said index of the most recently received record for each managed object, said next record having an index comprising said changed managed object, said next record index being lexicographically larger than the index of said most recently received record for each managed object, and means for receiving said next record for said changed managed object from said Agent and maintaining a record of said lexicographically larger index.
