How do you propose to fairly distribute market data feeds to the market if not multicast?
I expected your aggressive support for small packets was for fintech. An anecdote: one of the largest exchanges in the world used MX for multicast replication, which is btree or today utree replication, that is, each NPU gets replicated packet wildy different time, therefore receivers do. Which wasn't a problem for them, because they didn't know that's how it works and suffered no negative consequence of this, which arguably should have been a show stopper if we need receivers to receive it at a remotely similar time. Also, it is not in disagreement with my statement that it is not addressable market, because this marker can use products which do not do 64B wire-rate, for two separate reason either/and a) port is no where near congested b) the market is not cost sensitive, they buy the device with many WAN ports, and don't provision it so that they can't get 64B on each actually used ports. -- ++ytti
