数字化气田分布式仓储系统中负载平衡技术的研究与实现

Research and Implementation of Load Balance Technology In Distributed Storage System of Digital Gas Fields

介绍我们在进行数字化气田分布式仓储系统研究设计时采用的一种动态负载平衡技术。这项研究在体现数字化气田关键技术应用的同时,提出了数字化气田仓储管理信息系统的分布式负载平衡问题。动态负载平衡问题涉及到Agent迁移的触发机制、迁移的选择策略以及迁移机制的实现几个主要部分。OsAgent技术提供了CORBA对象搜寻的基本功能,它可以定位实现特定对象的有效服务器。这种动态负载平衡技术在数字气田仓储管理信息系统中已经得到了实际应用,并取得了良好的效果。

This paper introduces a dynamic load balance technology we have adopted in our study and design of the distributed storage system of digital gas fields. This study embodies the key - technology application of digital gas fields, in the mean time, it puts forward the distributed load balance of digital gas fields＇ storage management information system. The dynamic load balance problem is related to several main parts such as the trigger mechanism of Agent transfer, transfer choice strategy and implementation of transfer mechanism. And that, the OsAgent technology offers fimdamental functions of CORBA＇ s object searching which can implement the effective servers of particular objects by position. The dynamic load balance technology has been actually applied in the storage management information system of digital gas fields and obtains good effect.
