Hi, Ciao, Hannes:

Thank you for your response!

I did contact Tolga for this issue. Actually it was Tolga who suggested
me to raise this issue to the DIME mailing list.

Once the work item for Diameter overload control is restarted we can
provide our comments in detail.

Thank you for the RADEXT draft document. I briefly took a look at that
document. I think using an application request to detect the overloading
status of a RADIUS server might be more appropriate for RADIUS than for
Diameter, mainly because there is no full heart beat (watch dog) message
for the RADIUS protocol which builds on connectionless transport
protocol UDP. But for Diameter I think that re-using the existing heart
beat message (DWR/A) to convey the loading status is better than
introducing additional application request messages, which will make the
existing logic more complicated and there will be interworking issues
among multiple versions of the application protocols.

Regards,
Alan
