民航旅客信息系统HTH报文成组并发控制优化

Hostto Host（HTH）报文交换协议广泛应用于民航旅客运输业中，随着民航系统业务模式和交易量的高速发展，对HTH报文处理的要求也越来越高。提出了一系列报文成组并发控制的技术解决方案．通过合理调配有限的系统资源，在满足业务功能要求的前提下，有效提升系统的访问容量和并发处理能力。据实测效果，应用新技术架构后，相同压力下的无会话报文对系统资源需求量降为原来的1／16，在大容量、高并发的复杂报文交互环境下，能够通过灵活的资源配置，保证核心业务的持续响应能力。

Optimization to HTH Message Grouping Concurrency Control in Aviation Passenger Service System

Host to Host （HTH） message exchange has been widely applied in the air transportation industry. Along with the rapid development of the Chinese air transportation market, the demands on cross-application and intersystem information exchange create challenges to the information system architecture. This article makes research to the infrastructure of HTH message grouping concurrency control, and raises a series of optimized logic to the existing design. It also introduces the proven practice of applying this optimization to the new infrastructure, which significantly improves the message exchange concurrency in a high-volume real-time transaction environment. According to a performance benchmarking in the production environment, this optimization reduces the system spend to 1/16 under the same throughput condition.
