Embodiment Construction

[0031] The present invention mainly includes three aspects: a network topology based on virtual mapping, a load balancing algorithm based on content replication, and a distributed resource monitoring structure adapted to the network topology in the present invention.

[0032] 1. A network topology based on virtual mapping.

[0033] Abstract the storage resource nodes belonging to the same local area network into a resource storage center. Set up a shared folder on each resource storage node in the resource storage center, and map the shared folder to a virtual drive letter on the central server. The information (such as disk space, bandwidth, credit, etc.) of each resource storage center is managed by the global management center.

[0034] 2. Load balancing algorithm based on content replication

[0035] (1) Each resource storage center node first establishes the resource statistics database of the node. The resource statistics database records the historical access conditi...

Abstract

A resource load balancing method concretely relates to content copy based resource load balancing method and an automatic distribution type resource monitoring structure. The method comprises: dynamically copying content of resource starting from every independent resource storage center node according to resource access condition of local node and information of resource storage center, selects a proper resource storage node for copied resource, at last accomplishes load balancing for resource. The resource storage center information such as bandwidth, magnetic disc space and credit needed by load balancing are collected and stored in monitoring information database of global hot spare management center by distribution type resource monitoring script program.

Description

technical field [0001] The invention relates to the field of computer networks, in particular to load balancing technology, in particular to a resource load balancing method based on content replication. Background technique [0002] With the rapid development of the network, more and more geographically distributed resources are gathered through the network. Since the resources themselves are distributed, and the visitors or users of the resources are also distributed, some new data management structures, typically data grids, are developed to manage these massive distributed resources, thereby providing Visitors provide efficient resource access services. When a large number of distributed users access the same large number of distributed resources, load imbalance will inevitably occur, that is, some local resources have too much access, while other resources have too little access. This load imbalance is caused by uneven access to resources. [0003] The current load b...
