Hi,

> - Why do we nominate by putting the valid pair in the triggered check queue?  Why not just say "send a binding request"?  In particular reason?
> Do we *want* it to be delayed if there are many things in the front of the queue?

I wonder whether the reason is to maintain the pacing among the CHECK LISTs, i.e., to make sure that the nomination request transaction for CHECK LIST X is not initiated at the same time as a connectivity check transaction for CHECK LIST Y?

But, even if we put the pair in the TRIGGERED CHECK LIST, we need to make sure it becomes the top-most pair in the list, because we don’t want to test other pairs that may still be i the list.

Regards,

Christer
