Hi,
I'm exploring ways to implementing PGM on Linux. (PGM is a basic
multicast protocol [ http://research.microsoft.com/barc/mbone/pgm.aspx ]
which is currently implemented in Windows XP and in Cisco routers.)
Am I right to think there are three possible approaches to implementation?
1) write an implementation as a contribution to the kernel;
2) write a kernel module to be maintained perpetually out-of-tree;
3) implement the protocol in userspace (raw IP / netfilter?)
What would you recommend? Alternatively, this thread:
http://www.uwsg.iu.edu/hypermail/linux/net/0310.2/0027.html
http://www.uwsg.iu.edu/hypermail/linux/net/0310.2/0030.html
suggests a view that ipv4 multicast is de-facto irrelevant, unused and
critically buggy at the (linux?) ethernet layer. Does this imply you have
a similar view of the relevance of the PGM protocol?
