Re: ASP active procedure

Hello Deepak,

I understand that there needs to be local check whether stack is ready to
receive traffic for that routing key.

lets assume all those scenarios are satisfied. and i am pretty sure that
when RFC says MAY, it has taken all these cases into account (for example
you can read from NOTIFY procedures - for NOTIFY to be sent, lot of
conditions needs to be satisfied - like n number of ASP's being active. Yet
RFC uses the words like MUST or SHOULD) .

If traffic modes are to be taken into account, what should act as trigger
for sending ASP Active message from a perticular ASP?

Hence my opinion is ASP Up Ack is only a sufficient condition, where-as
NOTIFY from peer acts as necessary condition.
can any comment on that?
