SubjectRe: Minimizing dropped UDP packets
> The real fix is to add flow control of course.

I'm not so sure---it's very attractive for data acquisition
devices to throw generic UDP packets onto the net to be vacuumed
up by general-purpose machines. (Multicast can be nice
here too; load balancing, redundancy.)

For example, UDP goes nicely into an FPGA. TCP would be almost
unthinkable. Even a UDP back channel for roll-your-own simpler
flow control would be almost as bad; also, any flow control
restricts you to unicast.
