19. 4008 Industrial Ethernet Switch can break a network into 8 distinct data links or segments also called collision domains Since all Ethernet nodes are able to recognize the occurrence of a collision and since the detection of a collision is principal to the way Ethernet arbitrates media access large domains containing many nodes can become quite cumbersome Thus using an Ethernet switch to subdivide a large network into separate collision domains will certainly help to increase throughput The current tendency in critical industrial control applications is to connect one Ethernet device per switch port This will produce the most deterministic mode of operation as the switch can then operate full duplex with no chance of collisions This ensures determinism helping critical control applications to remain predictable and on time Each port of a switch forwards data to another port based on the MAC address contained in the received data packet frame In order to know which port to forward a data packet to the switch will learn and store the MAC addresses of every device it is connected to along with the associated port number However until the switch actually learns the port a particular address resides at the first packet it forwards this traffic to all ports just like a hub The switch will use its internal look up table to quickly determine the location port of a node establish a temporary connection between itself and the node then term
