Many approaches have been proposed to analyze the properties of Petri nets. Among them, reachability analysis is a fundamental method for studying the dynamic properties of Petri nets. However, state space explosion has obstructed its applicability for analyzing large-scale systems. This paper presents a new method to attack state space explosion based on the concept of compositional verification. The strength of our method is in preserving the global information of Petri nets and a set of more effective condensation rules especially for tightly coupled modules (subnets). The current version of our method provides an efficient analysis for detecting deadlock states. An extension of our method for detecting reachable markings is also described.","PeriodicalId":129829,"journal":{"name":"Proceedings. IEEE High-Assurance Systems Engineering Workshop (Cat.

Active Multimedia Communication Systems 有源多媒体通信系统

{"title":"Active Multimedia Communication Systems","authors":"Shi-Kuo Chang","doi":"10.1109/HASE.1996.618594","DOIUrl":"https://doi.org/10.1109/HASE.1996.618594","url":null,"abstract":"To maintain continuous, adaptive multimedia communication with guaranteed minimum quality of service in a combined wired and wireless environment poses a major challenge. We describe an active network architecture for multimedia communications. We introduce the novel concept of QoS-Message, which is specified by a flexible, high-level Petri net called the G-Net. Extensive research has been done at the University of Pittsburgh and elsewhere to study the property of G-Net and its application in the design of complex, reliable real-time systems. We adopt the G-Net for QoS-message specification. An active net- work architecture is describe so that based upon the feedback from the network, the optimizing transforma- tion of G-Nets enables the continuous adaptation of QoS-messages when the network environment changes dynamically. The approach guarantees continuous communication over a combined wired and wireless en- vironment. A prototype active multimedia communication system is being developed at the University of Pittsburgh. This research provides a basis for QoS-message specification, dynamic QoS-message construc- tion, a channel model and an active network architecture for adaptive multimedia communication.","PeriodicalId":129829,"journal":{"name":"Proceedings.
