Problems solved by technology

The disadvantages of this file system: (1) The system is not based on a unified framework, so that the communication of different types of servers in the system does not have unity and versatility
(2) The system does not store files in fragments, so that when storing large files, the storage fraction is higher and the storage space is more wasted
(3) The system does not copy the files. When the data node fails, the file system is unavailable, which reduces the availability of the system.
(4) The system does not provide support for file band transfer and parallel transfer, and the performance of using this file system is low

Description

technical field [0001] The invention relates to a data grid system in the field of electronic information technology, in particular to a distributed traffic information storage file system. Background technique [0002] With the increasing number of grid applications, not limited to the initial application background - scientific computing, grid technology extends its tentacles to all walks of life, using grid computing at the level of network services, integrating existing The integration of some social public service resources has become a development trend. The traffic information grid is the product of the combination of grid technology and public services. The use of network services greatly improves the versatility of the grid so that it can better meet the needs of traffic information services. The data module is gradually separated from the underlying support module of the original grid technology. As a technology that integrates heterogeneous resources into one r...
