  • Patent number: 11368396
    Abstract: Virtual machine environments are provided in the switches that form a network, with the virtual machines executing network services previously performed by dedicated appliances. The virtual machines can be executed on a single multi-core processor in combination with normal switch functions or on dedicated services processor boards. Packet processors analyze incoming packets and add a services tag containing services entries to any packets. Each switch reviews the services tag and performs any network services resident on that switch. This allows services to be deployed at the optimal locations in the network. The network services may be deployed by use of drag and drop operations. A topology view is presented, along with network services that may be deployed. Services may be selected and dragged to a single switch or multiple switches. The management tool deploys the network services software, with virtual machines being instantiated on the switches as needed.

  • Patent number: 11368412
    Abstract: The disclosed systems and methods provide methods and systems for providing power throttling adapted for high performance network switches. A method includes determining, for each of a plurality of measurement periods within a thermal average period, an energy usage estimate for a packet processing block configured to process ingress packets at a power gated clock rate. The method includes determining, for each of the plurality of measurement periods, a target clock rate for the packet processing block based on the determined energy usage estimates to meet a target energy value that is averaged for the thermal average period. The method includes adjusting, for each of the plurality of measurement periods, the power gated clock rate towards the target clock rate, wherein the adjusting causes the packet processing block to process the ingress packets at the adjusted power gated clock rate.
