>Like you are probably ignoring source quench.
Source quenches are deprecated by RFC1812. RFC1122 is still the host
requirements RFC so technically hosts must still pay attention to them,
but routers are not supposed to send them.
4.3.3.3 Source Quench
A router SHOULD NOT originate ICMP Source Quench messages.
...
DISCUSSION
Research seems to suggest that Source Quench consumes network
bandwidth but is an ineffective (and unfair) antidote to
congestion. See, for example, [INTERNET:9] and [INTERNET:10].
Section [5.3.6] discusses the current thinking on how routers
ought to deal with overload and network congestion.
