Each server communicates with the master through a TCP-based Link State Algorithm (LSA) protocol developed in the transport core development team. Each server, including the master, is on TCP listening port 691 and registered with Internet Assigned Numbers Authority (IANA) for this purpose. The master broadcasts changes only to all servers in its routing group.
