  • Methods and apparatus for virtualizing switch control plane engine
    Patent number: 9836322
    Abstract: In some embodiments, an apparatus includes a scheduler disposed at a control device of a switch fabric system. 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.
    Type: Grant
