[Linux-HA] Documentation of heartbeat protocol

I've done some googling, and read a lot of the source - I can
reverse-engineer most of the heartbeat protocol, but would like a
definition of the various exchanges, and how each node is meant to
respond to various cases.

In particular I am interested to understand the meaning of the various
sequence numbers and so forth, and their implications when hosts
fail-over, die, return to active status etc. Basically the sort of
thing you would find in a protocol RFC.

Many thanks for any pointers.
