Re: delay before next login

["Julian Satran" <Julian_Satran@il.ibm.com>]

The text intended was Login.
Time2Wait is an advisory wait before
recovering tasks (that may start with a login).
Mallikarjun is right that a Login can
be stalled at target as well that is why Time2Wait is advisory.
There is no (direct) relation between
Logouts.

I think the text intended to say Logout (though one could realize an
implicit Logout via a Login PDU, the first intended action being Logout).

Here's the annotated sentence:

If Time2Wait is 0, the reassignment (when ErrorRecoveryLevel=2 and the
Logout response code is 0) or a new Logout (when Logout response code is
2 or 3) may be attempted immediately.

Note that the scenarios described in paranetheses above are the only
scenarios when Time2Wait is meaningful - all this sentence is trying to
do is specify what does a value of zero mean in those two scenarios, due
to the potential ambiguity around the usage of zero.

Going back to Eddy's question -

If there's such a need in certain implementations, I'd assume the target'd
easily
be able to make the next connect request/Login request wait.
