Our implementation already permits subsets of data to be sent on a session. We do have customers that utilize different sessions to convey different views (slices) of the data. We're already at the point where we've had discussions about applying policy to those sessions where a given station may be interested in a smaller portion of a given view. Internally at Juniper and also among applications like IETF BGP YANG, we've had discussions about what more targeted subscriptions might look like, and how that might be signaled. That said, it's better to not flail at the use cases for this. Our consequence of how the marking works is that it is guaranteed to be chatty if it's done in a traditional BMP streaming case. I'd encourage the authors and WG to consider what you actually want out of the feature for a use case. I suspect a desire for "secret sauce" is keeping people from being fully honest here. :-) -- Jeff _______________________________________________ GROW mailing list -- [email protected] To unsubscribe send an email to [email protected]
