  • Patent number: 11398991
    Abstract: In some embodiments, an apparatus includes a switch fabric having at least a first switch stage and a second switch stage, an edge device operatively coupled to the switch fabric and a management module. The edge device is configured to send a first portion of a data stream to the switch fabric such that the first portion of the data stream is received at a queue of the second switch stage of the switch fabric via the first switch stage of the switch fabric. The management module is configured to send a flow control signal configured to trigger the edge device to suspend transmission of a second portion of the data stream when a congestion level of the queue of the second switch stage of the switch fabric satisfies a condition in response to the first portion of the data stream being received at the queue.

A first edge device from the edge devices can be configured to be coupled to a first peripheral processing device from the peripheral processing devices. The second edge device from the edge devices can be configured to be coupled to a second peripheral processing device from the peripheral processing devices. The first edge device can be configured such that virtual resources including a first virtual resource can be defined at the first peripheral processing device. A network management module coupled to the edge devices and configured to provision the virtual resources such that the first virtual resource can be migrated from the first peripheral processing device to the second peripheral processing device.

  • Patent number: 11323350
    Abstract: In one embodiment, a processor-readable medium storing code representing instructions that when executed by a processor cause the processor to update, at a memory location, a first flow state value associated with a data flow to a second flow state value when at least one of a packet from the data flow is received or the memory location is selected after a time period has expired. At least a portion of the packet is analyzed when the second flow state value represents a flow rate of a network data flow anomaly.

  • Patent number: 10020888
    Abstract: An optical transmitter may generate a first optical signal having a first wavelength and a second optical signal having a second wavelength. The optical transmitter may output the first and second optical signals to a link without performing a multiplexing operation. The optical transmitter may output part of the first optical signal to the link while part of the second optical signal is being output to the link. An optical receiver may receive the first and second optical signals, via the link, as separate optical signals. The optical receiver may receive part of the first optical signal from the link while part of the second optical signal is being received from the link. The optical receiver may provide the first and second optical signals to a photodetector array that includes a first photodetector to detect the first optical signal and a second photodetector to detect the second optical signal.
