Abstract
Redundancy mechanisms are difficult to implement in a node holding connections spanning over a wide telecommunications network. Novel redundancy mechanisms to be implemented on a telecommunications node is described. In the mechanisms, an inactive device is maintained in hot standby with the active device so that a substantially hitless activity switch can be performed. The inactive device is kept in synchrony with the active device by updating the inactive device only when the status of connection has changed.
