摘要： In some embodiments, a non-transitory processor-readable medium stores code representing instructions configured to cause a processor to receive, from an access switch, a first signal including forwarding state information associated with a first peripheral processing device from a set of peripheral processing devices. The code can further represent instructions configured to cause the processor to receive, from the first peripheral processing device, a second signal including a data packet. The code can further represent instructions configured to cause the processor to send, to a replication engine associated with the set of peripheral processing devices, a third signal such that the replication engine (1) defines a copy of the data packet, which is included within the third signal, and (2) sends, to a second peripheral processing device from the set of peripheral processing devices, a fourth signal including the copy of the data packet.

摘要： In one embodiment, an apparatus includes a first network control entity associated with at least a portion of multiple physical ports at a first access switch that are operatively coupled to a peripheral processing device and a switch fabric. The first network control entity can receive a host protocol request from the peripheral processing device, the first network control entity to transmit the host protocol request to a second network control entity associated with at least a portion of multiple physical ports at a second access switch, such that the host protocol request causes the second network control entity to obtain a response to the host protocol request. The first network control entity can receive the response to the host protocol request from the second network control entity and transmit the response to the host protocol request to the peripheral processing device.
