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 .
