A realization method for simple network management protocol queue

Abstract

The invention discloses an implementation method of a simple network management protocol (SNMP) queue, comprising the following steps: a doubly linked list structure is adopted as the organization structure of the nodes in an SNMP queue to create the SNMP queue; moreover, the nodes in the SNMP queue are organized through the bidirectional pointer of the doubly linked list according to the lexicographic order of record objects in a data list, thereby completing the ordering of all record objects in the data list according to lexicographic order; response to a traverse operation request for acquiring next lexicographic order variable is completed; moreover, a next queried SNMP lexicographic order variable is returned in the ordering mode of the lexicographic order. The implementation methodis propitious to acquire a next SNMP lexicographic order variable by an administrator through quick inquiry, thereby increasing the response efficiency of a traverse operation request.

Description

technical field [0001] The invention relates to the realization technology of Simple Network Management Protocol (SNMP, Simple Network Management Protocol) queue, in particular to a method for realizing the SNMP queue in a real-time memory database. Background technique [0002] SNMP is currently the most widely used network management protocol in TCP / IP networks, and can be used in embedded systems. Then, as a common form of data management in embedded systems, real-time memory databases undertake all maintenance work on data. Of course, support for SNMP queue implementation is also included. [0003] For example, when the SNMP Get-Next-Request traversal operation is performed on variables with index values, the managed objects need to be returned to the manager in lexicographic order according to the requirements of SNMP. Here, the so-called Get-Next-Request refers to a process of obtaining the next SNMP dictionary variable based on a given index value. The so-called di...

Problems solved by technology

[0004] SNMP queues are not implemented in existing real-time memory databases. However, for the Get-Next-Request operation of SNMP, the data management forms implemented in existing real-time memory databases, such as record tables and index tables, cannot be sorted in the above-mentioned lexicographical order. The return operation provides effective query, which is not conducive to the manager to obtain the next SNMP lexicographic variable through quick query, thus reducing the response efficiency to the Get-Next-Request operation request
