Proposal to make path status sequence number per path. #396

Open mirjak opened 6 days ago

mirjak commented 6 days ago

fixed #312

This is a proposal to make the sequence number in the path_avaiable and path_standby frames per-path. It is more inline with how the sequence number used in the mp_new_cid and mp_retire_cid frames. However, both approaches are fine. Please discuss in issue #312 which one you prefer.

@Yanmei-Liu I think it best to have the discussion on the issue #312.

But just as a quick reply, it should never be an error in all paths are in standby; this is discussed in the doc. And also you don't really know if you missed a path status update because we only say the sequence number is monotonically increasing but that all values have to be used. So the sender should actually skip one. But even if you assume you missed one, I don't think that information is really helpful as you don't know what would be in there or when it will arrive, so you have to make a sending decision based on the information you have right now.

Let's not merge this PR now but have some more discussion at the next meeting first!
