摘要
数据传输系统作为信息系统软件核心构件,是各信息系统中心实现信息交互的前提与基础。论文在基于现有单节点数据传输系统的基础上,提出了分布式数据传输系统的关键技术设计,包括:集群动态组建、心跳守护、服务器注册、服务器发现和集群负载均衡管理。同时通过使用LoadRunner并发性能测试工具,对该分布式数据传输系统在不同集群规模和不同负载压力情况下的数据传输效率进行测试。
As the core component of information system, data transmission system is the premise and foundation of in- formation exchanging between different systems. This paper is based on the existing single node pattern, puts forward the key design of distributed data transmission system, including dynamic cluster formation, heartbeat daemon, server registra- tion, load balancing and so on. At the same time, through the use of concurrent LoadRunner performance testing tool, the efficiency of distributed data transmission system in different cluster sizes and load pressure is tested.
