Abstract: 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.

The scheduler is configured to receive a control plane request associated with the switch fabric system having a data plane and a control plane separate from the data plane. The scheduler is configured to designate a control plane entity based on the control plane request and state information of each control plane entity from a set of control plane entities associated with the control plane and instantiated as a virtual machine. The scheduler is configured to send a signal to a compute device of the switch fabric system in response to the control plane request such that the control plane entity is instantiated as a virtual machine at the compute device.

Abstract: In some embodiments, an apparatus includes a first network control entity configured to be implemented at a first edge device. The first network control entity is configured to receive a control packet from a peripheral processing device via a tunnel that is between the peripheral processing device and the first network control entity and that includes at least a portion within a second edge device. The first network control entity is configured to determine routing information associated with the peripheral processing device based on the control packet. The first network control entity is configured to send the routing information to a second network control entity such that the second network control entity routes a data unit addressed to the peripheral processing device to the second edge device without sending the data unit to the first edge device.

Abstract: 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.
