分布式环境下可靠数据同步及通讯的协议分析

摘要

With the increasing popularization of Internet technology, the application of distributed computing model in the enterprise becomes more and more important. In the past, the performance and reliability of the high performance and high availability environment have been paid more attention to the performance and reliability of the single computer. At present, the distributed computing model has gradually shifted to the same purpose. JGroups is a reliable multicast communication tool, and it provides a very good lightweight distributed computing model and implementation in many distributed computing communication models. In this paper, we try to analyze some important problems that need to be solved in the distributed computing, and analyze the complete solution of JGroups framework in the reliability and communication protocol of distributed computing.%随着互联网技术的日益普及，分布式计算模型在企业中的应用越发显得重要。以往在要求高性能、高可用性环境下进行业务复杂计算往往注重于单台高价计算机的运算性能和可靠性，目前在分布式计算模型趋于成熟之后已经逐步转向采用多台廉价计算机协同计算来达到相同的目的，对企业应用架构而言，这不但大大降低了企业采用高性能计算的成本，也在业务可扩展性上提供了敏捷的渠道。在众多的分布式环境下的计算通信模型中，JGroups作为一个可靠的组播通信工具提供了一个非常优秀的轻量级分布式计算模型及实现。本文试图从分布式计算需要解决的几个重要问题出发，详细剖析JGroups框架在分布式计算的可靠性和通信协议上所提供的完整解决方案。
