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.

摘要： In some embodiments, an apparatus includes a route reflector implemented in at least one of a memory or a processing device. The route reflector is configured to be included within a switch fabric system. The route reflector is configured to receive, from a network management module, an instruction to install a route associated with a multi-stage switch, and send the instruction to install to a route target network control entity associated with the multi-stage switch. The route reflector is also configured to receive, from the route target network control entity, a first acknowledgement signal indicating that the route was successfully installed at the route target network control entity. The route reflector is configured to send a second acknowledgement signal to the network management module in response to receiving the first acknowledgement signal.
