To use NameServer replication, you first configure multiple NameServers on one subnet to listen on the same UDP port. You then have each Unified Broker instance register with its controlling NameServer and have each client contact its connecting NameServer using the subnet broadcast address and the same UDP port number. Thus, Unified Broker registrations are automatically replicated in each NameServer, and client connection requests are handled by each NameServer. The first replicated NameServer to respond to a client request provides the Unified Broker connection.
