I agree. It seems we can close issue#32.

I assume editors will convert the agreed principles to propper specification text.

Ulrich,

Yes, with that period being long enough for the reporting node to be confident that all previously sent overload reports have expired.

Steve, Ben,



for my clarification, your proposal is to say



***

Sequence number is of type Unsigned64.



When generated, a new sequence number must be greater than the sequence number contained in the active overload report to which it applies (including over reboot of that node).  Note: this allows sequence numbers to start at 1 for the initial occurrence of an overload condition at a reporting node.

***



If so, what is meant by "initial occurrence of an overload condition"?



I guess it means something like moving from no overload to overload after a sufficiently long periode of no overload



Please clarify



Ulrich

Ulrich,



Would you agree to the following to replace the first two statements:



Sequence number is of type Unsigned64.



When generated, a new sequence number must be greater than the sequence number contained in the active overload report to which it applies (including over reboot of that node).  Note: this allows sequence numbers to start at 1 for any occurrence of overload at a reporting node.  This, I think, allows us to ignore wraparound issues as wraparound will never happen.  Unless we are worried about a server staying in overload for billions of years (assuming reports with a ten minute validity period refreshed every five minutes).



s/ any occurrence of overload / the initial occurrence of an overload condition





The other two statements are good.
