一种基于CORBA环境的两级双阈值负载平衡系统研究

为了实现分布式异构系统内负裁的均衡分布,提高资源利用率和系统的吞吐率,采用CORBA中间件技术能有效满足异构环境复杂性、均衡作用自适应性等特点.通过研究CORBA环境下的负裁平衡实现机制,提出相应负载平衡系统模型,同时设计了双层双阈值负裁平衡算法以实现异构系统下的负载收集与评估、服务动态预分配和迁移,提高系统的并行运行性能.

Research on Dual-level and Dual-threshold Load Balancing System Based on CORBA

An middle-ware based dynamic load balancing system was designed to balance the workload in a distributed inhomogeneous network system in order to enhance resource utility and increase system throughput, which can meet the needs of complexity and self-adaptability of load balancing by adopting CORBA. On the analysis of the related parts of CORBA, a model of load balancing system is presented, and furthermore, dual-level and dual-threshold algorithms are brought up, which can collect and evaluate the workload, can dynamically pre-assign services among nodes of CORBA system and can transfer services between nodes on the homogeneous subsystem. This algorithm can effectively improve the parallel performance of the load balancing system.
