Optimization to HTH Message Grouping Concurrency Control in Aviation Passenger Service System
Hao Peng · Journal of Civil Aviation University of China · 2011
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 inter-system 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.
