  • Dynamic transmission side scaling
    Patent number: 10560394
    Abstract: In one embodiment, a method includes assigning a number of threads for user plane functions to a corresponding number of transmit queues for transmission of packets on a network interface, assigning additional threads exceeding the number of transmit queues to software transmission queues associated with the threads assigned to the transmit queues, identifying a load at each of the threads, dynamically updating assignment of the additional threads to the software transmission queues based on the load at the threads, and transmitting packets from the transmit queues for transmission on a network from a physical interface at a network device. An apparatus and logic are also disclosed herein.
    Type: Grant
    Filed: September 22, 2017
    Date of Patent: February 11, 2020
    Assignee: CISCO TECHNOLOGY, INC.

  • In-service upgrade of kernel loadable modules
    Patent number: 10289398
    Abstract: In one embodiment, a method includes creating an active container and a standby container for a single supervisor of an operating system at a network device, instantiating instances for active Kernel Loadable Modules (KLMs) for servicing the active container, instantiating instances for standby KLMs for servicing the standby container, wherein one or more of the standby KLMs comprise upgraded versions of the active KLMs, and switching over from the active container to the standby container to perform an in-service upgrade of the KLMs for the operating system. An apparatus and logic are also disclosed herein.
