Large-Scale Network Performance Data Acquisition System Based On The Snmp Protocol

In recent years, with the rapid development of the Internet, the size of the network continues to expand. In order to ensure the quality of service in the large-scale networks, this paper designed and implemented a performance data rapid acquisition and efficient storage system based on SNMP protocol.The goal of this research includes collecting the numerous network performance data, processing and storing them under a large-scale network environment. So, the main works of this paper is as follows:(1) Described the function of network management system and network management protocol SNMP in detail, analyzed the performance data types and formats, combined with the performance data demands in the large-scale network environment, studied the network parallel technologies, and verified the feasibility of this project.(2) Designed a performance data acquisition and storage system based on SNMP protocol under the large-scale network, and implemented it using C language in each function module, including a) Task allocation and management module; b) Data sending and receiving module; c) Receive caching and storage module; d) Data compression module.(3) Tested the system and each module, focused on data acquisition module, storage module and compression module.Now there are a lot of network management systems in the industry, but less research on centralized network management system for large-scale network, this topic is to research the huge amounts data collection and storage technology in the centralized network management system and large-scale network environment, and has been implemented the system. So this paper has practical significance for performance data acquisition and storage in large-scale network.
