Hi Ijitsch and Gunter,
I fully agree that DDoS avoidance is a very important issue,
if SAVA can successfully resolve the problem of source address
(based on existing mechanisms and some new mechanisms)
then other WG can work on top of SAVA to resolve DDoS, to design trust
identifier
(based on trust/traceable infurstrucre) and resolve SPAM.
I just wonder how many goals we should put into a single WG.
Regards,
Jun
