Embodiment Construction

[0021] The present invention comprises network management data packet deduplication module, network management data attribute compression storage module, network management data retrieval module and network management compressed data recovery module composed of four parts, such as figure 1 shown. The details are as follows:

[0022] 1. Network management data packet deduplication module

[0023] For a given network management data record that is continuously recorded, it is grouped and stored according to a certain value range of a certain attribute according to the retrieval needs of the network management. For the data in the group, according to the data characteristics of the network management, remove the parameters that change frequently, and deduplicate the records. Identified duplicate records are stored in a separate storage area.

[0024] Let R(A 1 ,A 2 ...,A n ) is an n-tuple relational frame of certain network management data T, T has N records, and T is shown...

Abstract

The invention discloses a method and a system for performing lossless compression storage and retrieval on network management data and is applied to compression, retrieval, long-term storage and recovery of the network management data. The method comprises the following steps: reading an original network management data table, and performing packet compression storage on infrequent changed attribute value in advance; recording increments but not totals changed in an interval for continuous attribute values; performing compression by adopting packet storage for discrete attribute values; performing storage by adopting data sets after VLB variable length compression for record number sets; performing statistics and building indexes while the compression is performed according to preset query conditions. The system consists of four parts: a network management data packet de-duplication module, a network management data attribute compression storage module, a network management data retrieval module and a network management packed data recovery module.

Description

technical field [0001] The invention provides a method and system for compressing, storing and retrieving data in a relational database, especially suitable for massive network management data containing a large number of similar data records. Background technique [0002] With the development of information technology, the construction of communication network is developing in the direction of multi-service, multi-functional and high-speed. Provide high quality service. The network management system needs to collect, store, and process a large amount of network management data such as SNMP, Syslog, ICMP detection, and traffic. These data are generally requested and collected according to the time granularity of minutes or less. However, in order to realize the high-speed data retrieval of the network management system and meet the needs of limited storage capacity, the data collected a period of time ago are often combined and stored in a lossy way. It is unable to provid...
