摘要
CORBA为异构环境下的应用对象之间的交互提供了一个有效的交互和通讯平台,简化了应用系统的开发.典型的CORBA应用由多个对象组成,这些对象可能分布在不同的主机上,因此平衡系统负载将是改善和提高应用系统整体性的关键.分析讨论了已有的关于CORBA环境下的负载平衡策略存在的主要问题后,提出一个新的CORBA环境下的分布式动态负载平衡模型,实现了基于最短总体期望响应时间策略的负载平衡系统.
Distributed object computing platform CORBA is a powerful technology to integrating diverse applications within distributed heterogeneous environments.Typical CORBA applications are complex systems consisting of a large number of objects and using a large number of machines.Balancing loads of systems is important to improve the overall system performance.The paper analyses load balancing technologies used by the traditional distributed systems and details flaws of existed load balancing technologies in CORBA and describes a new prototype in CORBA environment.The model based on shortest overall excepted delay routing is implemented on Visibroker for C++4.0.
