Method of using simple network management protocol to act multirariant block inquiry

Abstract

The invention relates to a simple network management protocol SNMP agent multivariate group query method, which defines the data structure of the simple network management protocol agent management information database according to the management information database file, analyzes the simple network management protocol message, analyzes the variable body, and according to the simple network management protocol message The operation type processes each variable, sets the variable state and the working state of the variable, groups unprocessed variables in the variable body, calls the method of obtaining the value of the object in the group, and queries data according to the object information and variable index value information in the management information base , query the value of each variable in the successfully bound group, and mark the variable in the group as processed; if unsuccessful, process each variable in the group according to the simple network management protocol message operation type, set the variable state and working state, and repeat the preceding steps Until all variable working statuses are processed. The method of the invention realizes high-speed completion of multi-variable query and can greatly improve query efficiency.

Description

technical field [0001] The invention relates to an SNMP (Simple Network Management Protocol-Simple Network Management Protocol) agent multi-variable grouping query method. Background technique [0002] The network management mode based on the simple network management protocol SNMP is the manager-agent (M-A) mode, in which the manager refers to a piece of program code that issues network management commands and receives command responses, and provides a network management interface; and the agent (Agent) refers to A piece of program code that specifically executes the corresponding action of the network management command, and returns the action execution result to the administrator. The administrator uses the query command primitives such as GetRequest and GetNextRequest provided by the SNMP protocol to send network management commands to the agent. In these command primitives, multiple query objects can be bound at one time, and these bound query objects are called variab...

Obviously, querying these object values ​​one by one will repeat the same action, which is not only inefficient but also a waste of system resources
