If I'm not wrong the ethernet is a type of LAN (local area NETWORK) and
therefore there is a network even without routing or switching devices; the
edges of the networks are the hosts.
Anyway, I agree with Mr Gao that it will be usefull to have a distinguishing
name for the last network element, something like ONE "outest network element"
or END "edge netework device" or any other that may be chosen.
