[zeromq-dev] About multicast service

[Kenneth Adam Miller]

PGM tends to take advantage of the hardware acceleration that routers often
provide, and is widely supported. So, effectively, repeatedly multicasting
some data out to many destinations with just some processor based software
solution. But because this is an intensive task that is often performed,
having every bit of acceleration helps.

However, usually if you're performing this kind of acceleration, it's for a
large company that can afford to not only get things right, but also to
make them fast. Or, speed is critical and it's being taken into
consideration from the ground up.
