icmp source quench management

Gonzalo Araluce — Wed, 29 Sep 2004 06:36:22 GMT

Hi,
I would like to know if the HPX 11.11 components implements the reception of ICMP source quench. What kind of congestion management it would start when receiving this ICMP type of message ?. Does it stop sending ip packets to the sender of the icmp msg ? How does it clear this situation ?
We have an ip_send_source_quench parameter , but in this case ,do we have an ip_rcv_source_quench ?
Thanks in advance.

Here's an old thread on source_quench that may provide some help...or at least give you food for thought:

I'm focus on the icmp reception side. I'm studing the HP server side behaviour when it receives an ICMP 'source quench' message from a router connected to the lan. How does 'inetd' behaves ? How does it slow down the communication to let breathe the router .

HI ,
It won't slow down the router but one of them who is sending packet realises that packet has not reached the destination i.e. anyhow it got discarded so it resends the packets. This overall gets you the feeling of slower network.
