JMS Scheduling Model Design and Implementation Based on Priority Control in the SOA System

摘要

Priority control is important in information systems that are designed according to SOA because there are services which have different functions and qualities, and a large amount of concurrent service requests may also occur at some point. A message scheduling model based on priority control of the service consumer is proposed. By adding an overall control queue between service consumers and service providers, the high-priority service scheduling that demands real-time process and the "hanger" phenomenon that happens in low-priority users are both well resolved. Stress tests through LoaderRunner and the comparisons with traditional model show the effectiveness of the message scheduling model.
