讨论了在ＵＮＩＸ 原有的消息队列机制基础上设计和实现分布式实时消息通信机制的方法．该机制提供透明的消息通信接口，支持带时间期限约束的实时消息请求．用户在系统调用的参数中可以给定消息请求的时间期限，对于多个远程消息请求，系统能按紧迫程度排队，以保证实时性．系统还可以定时检测消息请求的期限，对能否在期限内完成进行预测并反馈给相应进程．
Discussed in the original UNIX message queue mechanism based on the design and implementation of distributed real-time messaging mechanism. This mechanism provides a transparent messaging interface that supports real-time messaging requests with time-bound constraints. The user can specify the time limit of the message request in the parameters of the system call. For multiple remote message requests, the system can queue up according to the urgency to ensure real-time performance. The system can also regularly detect the deadline for the message request, whether it can be completed within the deadline and feed back to the corresponding process.
