Re: FW: Request for review of IKEv2/IPsec failover solution draft

 In your previous mail you wrote:

   And last, your experience may be different, but I have yet to see an service

=> my experience is different but I know some service provider purchase boxes
from at least two different vendors for security reasons: the idea is to get
the service still provided even a bug, including a security flaw, crashs
all the boxes from one vendor. And this even it is not so easy: different
management systems, learning of different environments for critical man-
power, interoperability labs, etc.



PS: to agree about a key in a small group is not a hard crypto problem
(i.e., there are known and improved algorithms to do that).
A pure client-gateway proposal is a solution for the suspend/resume problem,
not any kind of failover problem.
