  • Software upgrade of redundant network components
    Patent number: 8019587
    Abstract: A method for upgrading redundant network components is disclosed. An application is installed on a network component. The network component is related as a redundant peer with a mate network component operating in an active mode and processing a stable call. The network component is placed in a standby mode. Data of a first version is transferred from the mate network component to the network component. The transferred data is converted from the first version to a second version. The mate network component is switched from the active mode to a standby mode. The network component is switched from the standby mode to an active mode to process the stable call.

  • Data replication for redundant network components
    Patent number: 7568125
    Abstract: In accordance with one embodiment of the invention, a method for replicating data for redundant network components is disclosed. Data associated with a call is received and stored in a shared memory database. The data is sent to a mate network component of the network component if the network component is in an active mode. Sending of the data to the mate network component is terminated if the network component enters a mode other than the active mode.

  • Data replication for redundant network components
    Patent number: 7007190
    Abstract: A method for replicating data for redundant network components is disclosed. An entry of a replication table of a shared memory database is assigned to a stable call. The replication table is associated with a network component operable to process the stable call. Data associated with the stable call is received and is stored in the shared memory database. The entry is updated in response to storing the data. The data is sent to a mate network component of the network component, and the entry is updated in response to sending the data.
