Abstract
Uninterrupted network operation is maintained when stations are moved, for example when a station is initially connected to a bridge port via a repeater, and the station is later moved to another repeater, such that the bridge filtering database is typically out of date until the station transmits packets. To remedy this, an intelligent agent causes a packet to be sent on behalf of the station via the new network segment, and causes the bridge to learn the new port for the station, and to update its filtering database. The intelligent agent sends this packet immediately after the station has been moved from one network segment to another, thereby minimizing the possibility that traffic directed to the station is lost.
