Packet switch operating methods and packet switches, using primary control circuitry of the packet switch, receive a request to perform a transaction. In response to the receiving the request, the primary control circuitry forwards the request to backup control circuitry of the packet switch. Subsequent to forwarding the request, the primary control circuitry performs the transaction by modifying a plurality of first data objects stored in a memory of the primary control circuitry. The packet switch operating methods and packet switches, using the primary control circuitry, inform the backup control circuitry that the primary control circuitry has performed the transaction and, in response to the informing, the backup control circuitry performs the transaction by modifying a plurality of second data objects stored in a memory of the backup control circuitry. The first data objects correspond to the second data objects.

Transaction-based coordination of data object modification for primary and backup control circuitry

A network switch assembly includes a first control entity, a second control entity, and at least one line blade. The first control entity is selectively configurable between an active state and a standby state. The second control entity is selectively configurable between a standby state and an active state. The at least one line blade communicates with at least one of the first control entity and the second control entity and has at least one port configurable to enable switching of information. One of the control entities is configured as an active control entity and another of the control entities is configured as a standby control entity. The active control entity is configured to transfer state information for the active control entity that is forwarded to the standby control entity. A method is also provided for rendering control.
