[e2e] Historical question: Link layer flow control / silent discard

[Detlef Bosau]

O.k., perhaps this is for all readers with grey hair (if there is still 
hair at all....) and grey beards ;-)


When I read the original catenet work by Cerf, the Catenet employed link 
layer flow control.

To my understanding, this was abandoned when the ARPAnet turned into the 
Internet (in 1981?). After this change, the link layer flow control was 
replaced by a "silent discard" of packets which cannot be accepted for 
delivery.

Is this correct?

What was the reason for this decision and have there been any 
alternative approaches?
