TCPGOSSIP
public class TCPGOSSIP extends Discovery (Code)
The TCPGOSSIP 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 contacting one or more GossipRouters, which must be running at well-known addresses:ports. 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 TCPGOSSIP requests with a TCPGOSSIP response.

The FIND_INITIAL_MBRS event will eventually be answered with a FIND_INITIAL_MBRS_OK event up the stack.
