I'm building applications for collaborative 3D graphics
using SRM (actually LRMP) multicast on the local Ethernet.
They're peer to peer systems, not in the new buzzword of
the day sense, but in all being equal participants rather
than a client/server design.
My systems have multiple senders, but a per-group routing
tree rather than per-source is fine. In the future I'll
want (like many VR/distributed sim folk) to be able to
allocate from a large range of multicast addresses, say
12 bits or more. Waiting for IP6 isn't an option.
The "Interconnections" 2nd ed book describes a shared tree
multicast with 8 byte group IDs that would fit my needs
very nicely. Can anyone point me to a working group/mailing
list where I can find out more about this?
