基于IIPP和移动Agent的冗余数据一致性的研究与实现

摘要

Redundancy technology plays an important role in improving the data reliability and availability,and the subse-quent data consistency problem becomes a hot research topic. A consistency model based on IIPP and mobile Agent is put for-ward. Under the guide of IIPP idea,operations such as transaction sending,transferring and distribution are conducted by means of the mobile feature and task processing feature of Agent to finally realize the weak consistency of data. The model was well verified in practical application,which improves the intelligence,efficiency and adaptability of the system.%冗余技术在提高数据可靠性和可用性方面发挥了重要作用,随之而来的数据一致性问题成为研究热点.提出一个基于IIPP和移动Agent的一致模型,在IIPP思想的指导下,应用Agent具有移动特性和处理任务的特性来进行事务的发送、转换及分发等操作,从而实现数据的弱一致性.该模型在实际应用中得到了很好的验证,提高了系统的智能性、高效性及自适应性.
