摘要： In some embodiments, a network management module is operatively coupled to a set of edge devices that are coupled to a set of peripheral processing devices. The network management module can receive a signal associated with a broadcast protocol from an edge device from the set of edge devices in response to that edge device being operatively coupled to a switch fabric. The network management module can provision that edge device in response to receiving the signal. The network management module can define multiple network control entities at the set of edge devices such that each network control entity from the multiple network control entities can provide forwarding-state information associated with at least one peripheral processing device from the set of peripheral processing devices to at least one remaining network control entity from the multiple network control entities using a selective protocol.

摘要： In some embodiments, an apparatus includes a compute device to communicate with a network control entity at each access switch from a set of access switches that define a portion of a data plane having a switch fabric coupling as hierarchical peers each access switch from the set of access switches. The compute device is operable to define a portion of a control plane that includes the network control entities from the set of access switches such that the compute device is hierarchically removed from the network control entities from the set of access switches. The compute device is operable to receive forwarding-state information from a first access switch from the set of access switches. The compute device to send the forwarding-state information to a second access switch from the set of access switches.

摘要： In some embodiments, a switch fabric system includes multiple access switches configured to be operatively coupled to a switch fabric. The multiple access switches include multiple ports each to be operatively coupled to a peripheral processing device. A first set of ports from the multiple ports and a second set of ports from the multiple ports are managed by a first network control entity when the switch fabric system is in a first configuration. The first set of ports is managed by the first network control entity and the second set of ports is managed by a second network control entity when the switch fabric system is in a second configuration. The second network control entity is automatically initiated when the system is changed from the first configuration to the second configuration.
