Abstract: In some embodiments, a system includes a first network control entity, a second network control entity and a third network control entity. The first network control entity and the second network control entity are associated with a first network segment. The third network control entity is associated with a second network segment. The first network control entity is operable to send to the second network control entity an identifier of the first network segment and forwarding-state information associated with a data port at a first network element. The second network control entity is operable to receive the identifier of the first network segment and the forwarding-state information. The second network control entity is operable to send the forwarding-state information to a second network element. The first network control entity does not send the identifier of the first network segment and the forwarding-state information to the third network control entity.

Abstract: 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.

Abstract: In some embodiments, an apparatus includes a first network device configured to receive, from a second network device, a first forwarding-state packet associated with a peripheral processing device and having a first generation identifier. The first network device is configured to receive, from a third network device, a second forwarding-state packet associated with the peripheral processing device and having a second generation identifier. The first network device is configured to implement forwarding-state information included in the first forwarding-state packet based on a comparison of the first generation identifier and the second generation identifier.

Abstract: 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.

Abstract: In some embodiments, an apparatus implemented in a memory and/or a processing device includes a first network control entity to manage a first data plane module associated with a port from a set of ports at a first access switch. The first network control entity associates an identifier of a peripheral processing device operatively coupled to the port from the set of ports with a next hop reference. The first network control entity provides the next hop reference to a second network control entity that manages a second data plane module at a second access switch such that the second data plane module can append the next hop reference to a data packet when the peripheral processing device is within a data path between and including the second access switch and a destination peripheral processing device.
