Real-Time Event Framework based on Component Model for Distributed Real-Time Systems

摘要

An Event Service is needed for providing event delivery occurring large-scale distributed applications such as multimedia communication, electronic commerce, and traffic control system. It supports asynchronous communication between multiple suppliers and consumers required by the distributed systems. However, the event service specification lacks important features required by applications with real-time requirements as follows; event filtering real-time scheduling, Quality of Service (QoS), and component management. Thus, this paper proposes a Real-Time Event Component Package (RTECP) Framework for distributed real-time systems. The RTECP Framework base on CORBA Component Model (CCM) and includes the following realtime features; event filtering component, real-time manager component, event monitor component, QoS management Component and QoS repository. Especially, this paper concentrates on providing suitable event filtering component for real-time service to meet various real-time QoS requirements under the distributed system environment.
