Industrial Automatic Control Systems and Controllers Annotation << Back Service Messages and Conversations in the Network Special Purpose V.M. Sobol Discusses the algorithmic characteristics of priority service messages and direct documentary in-network for special purposes, as well as elements of the optimization strategy transfer in order to improve the efficiency of information exchange. Analyses various options for potential conflict situations arising while receiving and outputting data coming from multiple sources in the recipient’s terminal equipment. Along with the static processing algorithm of conflict situations is the dynamic model of the functional tasks in the notations of extended Petri nets. Are the fragments of the methodology of creation of various conflict situations of checks and verification of the correctness of procedures when the priority service of communications and negotiations. The proposed algorithm optimization of information exchange with the system is based on the delivery of a message, including multicast, combined with the technological process input subscriber sending a perforate message that allows you to almost halve the time bringing to subscribers-recipients.
