Simple Module EtherHub

Package: inet.linklayer.ethernet
File: src/linklayer/ethernet/EtherHub.ned

A generic wiring hub model.

ethg[i] gates represent ports. Messages arriving on a port are broadcast to every other port.

The connections should have data rate set to zero. Cable lengths should be reflected in the delays of the connections.

Messages are not interpreted by the hub model in any way, thus the hub model is not specific to Ethernet in any way. Messages may represent anything, from the beginning of a frame transmission to end (or abortion) of transmission.

Used in compound modules:

If a module type shows up more than once, that means it has been defined in more than one NED file.

LargeLAN (compound module)	Several hosts and an Ethernet hub on a switch. One port of the hub connect to a 10Base2 segment.
