I don't know for certain what "uplink" and "downlink" are either, but 
based on their usage, I strongly suspect they are British English 
words to respectively describe "onramp" and "offramp" (in US English).

BTW, "control city" is the name I have heard transportation/highway 
engineers use to describe the name of a "destination" on a sign 
telling you that if you continue (straight, either in this lane or 
via this onramp) you "go here."

For example, around here, there are two ways to get north to San 
Francisco:  either via the coastal route on Highway 1, or "over the 
hill" (Santa Cruz mountains) via Highway 17, through Silicon Valley 
and up the Peninsula.  For the former, the "control cities" listed on 
highway overhead signs are:

Half Moon Bay
San Francisco

For the latter, they are:

San Jose
Oakland

(and then you interchange to I-280 to get from 17 to San Francisco, 
otherwise you head to Oakland).

I'm not advocating that we change the destination tag to 
control_city, just making an observation that might be helpful for 
discussion purposes here in the USA.
