摘要： Methods and apparatuses for process a crossconnect switchover in a network element are described. According to one embodiment, an exemplary method includes synchronizing state information regarding broadband subscriber sessions of one or more circuits of a network element between one or more hub devices of an active control card and a standby control card of the network element, and in response to a crossconnect switchover, starting up one or more sessions associated with the one or more hub devices of the standby control card using the synchronized information, such that the one or more sessions are started up as if they are restarted. Other methods and apparatuses are also described.

摘要： Techniques for providing resilient multicast traffic processing in a network element are described herein. In one embodiment of the invention, a network element separately joins equivalent multicast traffic streams at a first and second interface respectively. During uninterrupted operation, the network element processes the packets of the multicast traffic stream it receives at the first interface and drops the packets of the equivalent multicast traffic stream it receives at the second interface. Upon an interruption of the packets of the multicast traffic stream being received at the first interface, the network element transitions to processing the packets of the equivalent multicast traffic stream it receives at the second interface. Other methods and apparatuses are also described.
