upstream and downstream routers

[Gwiz00]

Hello,

Can somebody please explain the concept of upstream and downstream?

Upstream is data you are sending, downstream is data you are receiving.

Carlsberg don't run I.T departments, but if they did they'd probably be more fun.

thank you very much.
So, lets say i have a BGP with an ISP, so that provider is upstream to me, and i am downstream to him.Right?

 

[Grenage]

I'm not really very knowledgeable on the BGP protocol, but yup, that should be correct.

When I am connected to the internet on my computer here, when I send a file to another computer, that's upstream (for this computer). Downstream obviously being when I download from that computer.

Carlsberg don't run I.T departments, but if they did they'd probably be more fun.

i think usually its safe to say "upstream" are provider routers and "downstream" would be your internal or customer routers.

i dont hear the term downstream used to often though.
