The article describes a proposed theoretical model of the switch. The built model is based
on the structural features of the frame of Ethernet technology. We considered the opera-
tion of a hypothetical switch of any hierarchical level of a topological scheme of con-
structing transport system of network. The calculated dependences are aimed at determi-
nation of probability and mathematical expectation of the time interlocking frames in
switches that implement the second level of the reference model ISO/OSI. A connection is
established between the magnitude of the switch delay and requirements of buffer
memory required of its input and output ports for all topologies of intersection infor-
mation flows in the transport systems.
Keywords:
computer network, transport system, transit node, switch, blocking, delay, buffer
memory.
