org.nasutekds.server.replication.protocol.TopologyMsg
This class defines a message that is sent: - By a RS to the other RSs in the topology, containing: - the list of DSs directly connected to the RS in the DS list - only this RS in the RS list - By a RS to his connected DSs, containing every DSs and RSs he knows. In that case the message contains: - the list of every DS the RS knows except the destinator DS in the DS list - the list of every connected RSs (including the sending RS) in the RS list Exchanging these messages allows to have each RS or DS take appropriate decisions according to the current topology: - a RS can route a message to a DS - a DS can decide towards which peer DS send referrals ...
