EthernetLink

channel

EthernetLink provides a base channel type for Ethernet connections with configurable length and propagation delay. It extends the Cable type and calculates the delay based on the physical length of the cable(1,2,3) and the speed of light in the medium.

The EthernetLink serves as a base for specific Ethernet standards with different data rates, from 10 Mbps to 400 Gbps.

MixedMultidropNetwork	network	This module contains an ~EthernetSwitch connected to a ~StandardHost and a 10BASE-T1S multidrop link with a configurable number of nodes. The switch port acts as the controller of the multidrop link. The network node type can be configured for all the nodes on the multidrop link.
