Analysis of treatment process segments-blocking switching scheme taking into account the diversity of communications channels
Industrial high-performance routers are essential components for building secure networks for remote control and monitoring of industrial facilities. The main function of the router is to read the packet headers of network protocols received and buffered on each port, and decide on the further route for the packet to follow its network address, including the network number and node number. This article discusses the mathematical model of the processing of segments in the router (switching node). In a fully accessible switching circuit, any input can be connected to any output if the latter is in the idle state (not busy servicing any call). In incomplete schemes, this condition is not fulfilled, all inputs and outputs are divided into groups, and certain groups of inputs have access (connectivity) to certain groups of outputs. If the description of the switching node from the specified positions requires only knowledge of the number of inputs and outputs, then the description of the switching system of incompletely accessible circuits indicates the number of groups of inputs and the ability to access certain groups of inputs to certain groups of outputs.
