Embodiment Construction

[0037] The present invention will be further described below in conjunction with the accompanying drawings and embodiments. Deduplication based on memory and file system is an independent module in the billing system, and its standard software model is as follows: image 3 shown

[0038] The specific implementation steps are:

[0039] ●Configuration information

[0040] Step 1 Configure information, configure the deduplication type (full deduplication, cross deduplication, no deduplication) and filter information acquisition method according to the deduplication business requirements of each business.

[0041] Step 2 Plan and create a file directory for storing files of filtering information.

[0042] Step 3 Set the time window parameters for memory storage according to the real-time degree of the business and the memory size.

[0043] ●During the implementation process, the configuration parameters of the deduplication system are saved in files in XML format. According t...

Abstract

The invention relates to an implement method based on mixed tautology removal of an HASH algorithm memory and a file system, which adopts the combination of the tautology removal of the memory and the tautology removal of the file system so as to achieve a win-win result of data storage use space and processing efficiency. The implement method has the procedure that tautology removal information in a certain period of time is loaded into the memory and the tautology removal of the memory is adopted, and beyond the time the tautology removal of the document is adopted. The implement method mainly has the following steps: step 1. tautology removal configuration information (record format information, tautology removal types) is loaded into the memory; step 2. the tautology removal information in a certain period of time (configurable) is loaded into a private memory; step 3. the tautology removal of memory is performed, i.e., the tautology is removed according to the filtering information in the memory; and step 4. tautology removal of a file is performed, the tautology is removed according to the historical filtering information in the file. The storage structure of the information of the tautology removal in the memory has two characteristics of HASH lists and time window.

Description

1. Technical field [0001] The invention relates to the field of deduplication processing in the billing system of the telecommunication industry, in particular to a deduplication technology based on HASH algorithm memory and file system mixing. 2. Background technology [0002] With the rapid increase of business volume in the telecommunication industry, the deduplication part is an important part of the entire billing system process, and its performance will inevitably affect the performance of the entire billing system. How to maximize the performance of the weight removal module is an urgent problem to be solved. The purpose of deduplication is to remove heavy single (repeated record) in the file; The applicant has proposed CN200610038375 based on the filter sheet memory deduplication method and CN200610085767 based on memory-based massive call list fast cross deduplication method, but the deduplication efficiency is still There is a need to improve. [0003] In the pre...
