RFC 1812, "Requirements for IPv4 Routers," deprecates use of source
quench. While you will see it on some exams and should know the
definition, source quench is not used as a congestion management
approach in modern networks.
>SOURCE QUENCH:
>
>The Source Quench message is used when IP needs to
>perform congestion control. An intermediate router or
>the destination host unsually sends an ICMP Source
>Quench message for every datagram that it has to drop.
>
>The source, on receiving the Source Quench message,
>loweres the rate at which is sends the datagrams. It
>keeps lowering the rate as long as it receives the
>Source Quench messages. Since there is no ICMP
>message to indicate that the originator of the Source
>Quench message is releived the host begins increasing
>the rate when it stops receiving the Source Quench
>messages.
>
>It continues to do so until it either reaches the
>maximum rate or starts receiving the Source Quench
>message again.
