Optimized transcript distributing method in data grid

Abstract

The invention relates to an optimized transcript distributing method in a data grid, belonging to the field of grid computation, and concretely relates to a grid system, in particular to a transcript distributing method in the data grid system. The invention provides a distributed dynamic self-adaptive transcript distributing method in the data grid, aiming at reducing the access cost of the resource request party, and comprising the following steps of: calculating the transcript amount through the response time of resources; and determining proper transcript place via comprehensive consideration of factors of load factor, node performance, real-time bandwidth, and the like so that the transcript distribution can be dynamically suitable for variation of access request and the network communication state. Compared with the existing method for simply requiring transcript amount to improve the data access performance, the invention evaluates the transcript amount and the optimum transcript place from the overall situation of the system, thereby effectively balancing the relationship between the transcript amount and the transcript maintenance cost. The method is not only suitable fordata grid systems of read-only resources and particularly suitable for data grid systems with read-write data resources.

Description

technical field [0001] The present invention mainly designs an optimized copy distribution method in a data grid, belongs to the grid computing (Grid) field, and specifically relates to a grid system, especially the distribution of copies in a data grid system. Background technique [0002] As a new type of network computing platform, the purpose of the grid is to construct a dynamic virtual organization on a distributed, heterogeneous, and autonomous network resource environment, and to realize resource sharing and resource collaboration across autonomous domains within it. Data grid is the application and realization of grid technology in data management. Facing the heterogeneous environment of wide area network, it integrates various data resources distributed on the network, shields the heterogeneity of underlying physical resources, and provides general and reliable data for upper-layer applications. Data service, realizing the integrated access, storage and service arc...
