Multicast TFTP client and server
When downloading a file from a server to a client machine,
the file is split into packets and sent one by one, with
the client acknowledging every packet. When distributing one file
to many machines, this can either be done as many single transfers
(as
g4u
currently does, using FTP :), or to use a protocol that supports
multicasting, to send the file only once from the server, and
have all clients stand at attention, and reading the packets
that the server sends, and possibly detecting and requesting any
dropped packets. One such network protocol for the latter is
the multicast trivial file transport protocol from
RFC 2090.
Jared McNeill has worked on multicast TFTP support for some
time, and after extending NetBSD's tftp(1) command to act
as multicast TFTP client last week, he has also written a
corresponding server now.
See
his mail to tech-net
for more information, or have a look at
Jared's multicast-tftp-server page
directly.
Now let me finish my PhD thesis and then find a job where I can hack that
into g4u... :-/
