Management information accessible via SNMP is organized in the Management Information Base (MIB). Many management applications are based on management information within an MIB table. The management information useful for management applications may be located in some rows of an MIB table. Owing to the limitation of current SNMP GetNext and GetBulk services, it is usually inevitable to retrieve all the rows of an MIB table even if some of them are needed. As the size of the MIB table grows, the object retrieval will incur considerable bandwidth and latency. Without loss of the simplicity of SNMP, we propose a novel SNMP service, called GetRows, to provide the capability of object selection via SNMP. Using GetRows, a management application can specify criteria for evaluating rows of an MIB table. Only the object instances in the rows selected by the criteria will be retrieved. Thus, less bandwidth and latency can be achieved by using the proposed GetRows service. Copyright © 2006 John Wiley & Sons, Ltd.
