However it is possible to configure routers to forward this traffic allowing automatic partner configuration to be used in a routed environment. If there are only a few routers in the environment the amount of multicast broadcast traffic should be minimal. Push Partnerships As the name implies when a push partnership is configured changes in the WINS database are pushed to the remote WINS server. More accurately a WINS server with records to replicate sends a push notification to target servers those configured to use it as a pull partner alerting them that it has records to update on the target WINS servers. The push notification includes an owner table that lists the owner IDs and the highest version ID for each owner. The target servers compare this information with their own owner tables to determine which records to replicate. The target servers reply to the push notification with a pull request and the transfer of records takes place. Accordingly since a transfer of records will not take place until a pull request has been received by the server that sent the push notification pull replication is the single mechanism for replication. The process for push replication occurs as follows 1. The source WINS server receives updates to its database and based on a configurable threshold sends a push notification to the destination WINS server its push partner indicating that it has updates to replicate. 2. The destination WINS server for the notification the push partner responds by initiating a pull request to its pull partner the WINS server that sent the notification and the replication is initiated between the replication partners. Push replication is not schedulable according to an interval of time. Rather the WINS administrator configures an update threshold that will trigger a
