Abstract
A technique for an access node to synchronize the accessibility of a plurality of access nodes within a network is described. The technique receives an accessibility update and/or device update from a remote node. For the accessibility update, the access node compares entries in the accessibility update to the local accessibility table. If entries in the accessibility update are more up-to-date than the local accessibility table, the access node adjusts the local accessibility table to reflect the updates. The local access node compares the node identifier, heartbeat, and timestamp to determine whether and entry in the local accessibility table is up-to-date. For the device update, the access node compares entries in the device update to the local device table. If entries in the device update are more up-to-date than the local device table, the access node adjusts the local device table to reflect the updates.
