When describing network traffic flow, if a device is attached to an access layer switch and that is connected to a distribution layer switch and then to a core switch, is that correct to say that the access layer switch is up-stream from the distro switch and the core switch is down-stream from both the access and distro switches?
If there's a Firewall connected to the Coreswitch that seperates your network from the Internet, would that then be downstream from the core switch? Or do I have it in reverse? with all of the above(?), given that when you're downloading from the Internet the traffic is going "down-stream" to your client device .
