Class TCPPING
The TCPPING protocol layer retrieves the initial membership (used by the GMS when started
by sending event FIND_INITIAL_MBRS down the stack). We do this by mcasting TCPPING
requests to an IP MCAST address (or, if gossiping is enabled, by contacting the router).
The responses should allow us to determine the coordinator whom we have to contact,
e.g. in case we want to join the group. When we are a server (after having received the
BECOME_SERVER event), we'll respond to TCPPING requests with a TCPPING response.
The
FIND_INITIAL_MBRS event will eventually be answered with a FIND_INITIAL_MBRS_OK event up
the stack.
