Diner-Waiter pattern in distributed control

As a useful and proven methodology in object-oriented design, design patterns are playing more and more important roles in distributed control system design. To improve the real-time performance and resource usage in distributed control, this paper proposes a novel design pattern: Diner-Waiter pattern. Compared with the traditional event related design patterns, it has the advantages of: 1) less routing time with possibly the best service provided; 2) reducing unnecessary interruption to the event processors; 3) providing a mechanism for intelligent request routing for better quality of service. This design pattern is expected to benefit the design of event dispatching and task allocation in distributed systems
