PROCESS ANALYSIS OF DATA FLOW PRIORITY MANAGEMENT IN SOFTWARE SYSTEMS
Annotation
An analysis of service disciplines with fixed and dynamic priorities is carried out. The object of study is an intermediate node of a multi-service network, where five data streams with different intensities and router service time arrive. Queuing system with a heterogeneous flow of applications is used as a model of such intermediate node. Studies of the heterogeneous queuing system with priorities are conducted by a statistical method in GPSS World simulation environment under the assumption of different laws for the distribution of time intervals between the queues arrivals and their processing time. Time dependences of the queue time on data stream number for different combinations of distribution laws with fixed and dynamic priorities are derived.
