David - hope you could do it

I'll try my best. Would still appreciate if you could ask the room if someone else wants to share the load.

I cannot see how this is vaguely ready to look at in terms of standardization - I can see how someone may wanna try and do some research on this in the irtf - maybe

There's no signaling at all. Nothing to interoperate.

Still have an opportunity to misorder when an in-progress flow is switched to another path.

", "time": "2023-03-31T02:03:28Z"}, {"author": "Tony Li", "text": "

Misordering is more likely when deactivating a prefix. You're moving a flow from a presumably suboptimal path back to an optimal one.

In any case, ordering and latency are possible issues ANY time we change the routing table.

", "time": "2023-03-31T02:05:17Z"}, {"author": "Shaofu Peng", "text": "

Hi Tony, In the absence of a central orchestration of controller, when a node in the network implement local path switch, they cannot perceive the impact on how much traffic will be affected, which may lead to congestion on a link in the new path. Of course, it is exactly difficult to learn how much traffic will be affected, but if we have that knowledge, that will be more perfect.

", "time": "2023-03-31T02:06:48Z"}, {"author": "Jeff Tantsura", "text": "

@Tony - you might consider using a similar strategy as with adaptive routing/DLB and move the flow only if the interpacket gap is large enough not to cause reordering, it is somewhat less of an issue in the WAN (perceptionally) than in DC, but still something to think about

", "time": "2023-03-31T02:08:26Z"}, {"author": "Tony Li", "text": "

No argument. One of the more intensive ways of using this technique is also to monitor per-prefix traffic levels and decide to select prefixes to balance bandwidth utilization.

", "time": "2023-03-31T02:08:49Z"}, {"author": "Tony Li", "text": "

@Jeff we're not too worried about this, given that the alternative is packet loss.

", "time": "2023-03-31T02:09:30Z"}, {"author": "Tony Li", "text": "

But we don't want to thrash, either.

absolutely, rebalancing usually yields better results than binary on/off

IMO misorder is out the scope of this proposal...

It's not really out of scope. It's more that it's the lesser of two evils. :-)

Agree, I just think that it is another local behavior, similar to LFA, TI-LFA\uff0c and previously, we have not raised any concerns about the disorder of these local behaviors. This issue is addressed by other technology.

I'm incredibly confused [by the discussion, not the problem David Black describes], not sure what to put in the notes here.

I think David's point is very well-taken. If this problem (insofar as I understand what the speaker is trying to do!) were easy, it would already have been fixed. If there are low-hanging fruit special cases, then identify them and make the case that they're worth addressing, but I don't think that's been done.
