I don't really understand what the concept of a port is in Linux with regards to multicast. Basically, I want to use multicast on an internal network with many nodes. I want to use multicast IP addresses to delineate the message *type*. E.g., 239.0.0.1 for status monitoring, 239.0.0.2 for control messages, 239.0.0.3 for heartbeats, 239.0.0.4 for chatting, etc etc. Since I'm using the address space to delineate messages, can I just hard-code my port (i.e. make it always the same)? Put another way: what is the effect of having one host subscribe to multiple multicast streams, where each stream has the same port, but a different ip address? Is there a performance impact?
