Interesting, so what about using a multicast transport with a network of brokers? If all the brokers can see the multicast then they shouldn't need store and forward at all.
I'd recommend TCP if you want reliability. Currently we tend to use multicast purely for discovery as if a node misses a message due to packet loss (or the input buffer being full so the network card discards it) then a point-to-point redelivery mechanism is required which can cause network storms if you're not careful. We've got the start of a basic implentation of reliable UDP/multicast but its not completely flushed out and working just yet. If the messages are small (so they fit inside a single datagram) and you don't care about loosing them (such as for market data prices) by all means give multicast a try if you want. -- James ------- http://radio.weblogs.com/0112098/
