Re: Filter NTP traffic by packet size?

The business model seems clearer when offering filtering as a service
to downstream networks, the effects are narrowly scoped, and members
have control over the traffic they accept from the exchange, e.g. I
don't want to accept NTP traffic to any destination that exceeds
1Gbit/s, or is sourced from an NTP server on my blacklist. Giving
policy control to the downstream allows them to protect their networks
and make business decisions about how they want to prioritize services
and customers when resources are constrained.

Would exchange members pay for this type of control?

Speaking only for myself: No. The L2 IXes I connect to should use their
resources for packet switching, not filtering. Way too many things that
could go wrong if we go down the filtering path...
