Re: [Gluster-devel] Multicast Support?

[Vikas Gorur]

Gordon,

(Replying to both your mails)

Implementing multicast would be difficult since multicasting only
works for UDP, and GlusterFS relies on a TCP connection. Moving GlusterFS
to use UDP would require extensive changes and would bring many new problems
of its own.

Regarding the configuration you'd want to conserve bandwidth for some of your
machines, you could do something like this (shown for one machine):

             simple nfs-like
             glusterfs                  afr
low b/w box  --------> /mnt/glusterfs --------> other three boxen

                       high b/w box

I don't see how this helps, though. The high b/w box has to send writes
to the other three machines anyway, thus robbing them of their bandwidth?
