[e2e] Why do we need congestion control?

[Detlef Bosau]

In addition to erasure codes:

TCP provides /reliable/ transport.

In the general case, you neither know your corruption ratio nor your 
drop ratio. So you cannot really determine a necessary "code strength", 
as you cannot predict the necessary attempts of retransmissions.

The game erasure codes vs. retransmissions seems like running in a 
vicious circle to me.
