  • Patent number: 9521079
    Abstract: A network device having a plurality of packet forwarding elements, each including a hardware component for receiving and forwarding data packets from and to other network devices via a plurality of input ports connected to a network. Each hardware component is configured to determine whether a received data packet is one of a predetermined class of data packets based on data in the received data packet and, if so, generate expedited processing instructions corresponding to the received data packet based on data in the received data packet. The hardware component forwards the received data packet, together with the corresponding expedited processing instructions, directly to the hardware component of all packet forwarding elements of the plurality of packet forwarding elements for processing based on the expedited processing instructions.

    Abstract: A method of transmitting an upstream communication packet from a distributed trunk (DT) switch is described. The method comprises receiving a packet from a device connected to a DT port of the DT switch; and transmitting the received packet via a non-DT port of the DT switch if the DT switch is the owner of the device and transmitting the received packet via a DT interconnect (DTI) port of the DT switch if the DT switch is not the owner of the device.

  • Patent number: 9210091
    Abstract: System and methods for metering output packet traffic at network devices. Ingress packet lookups are employed in combination with egress packet meters, which can be arranged in parallel fashion, and used to meter traffic across multiple blades of a switch chassis. Also, egress packet traffic metering is accomplished while matching complex ingress rules without additional egress packet processing. The system has a first node for creating requests that contain a number of filter indicies for specifying packet forwarding criteria. The first node also specifies values for the filter and meter indicies based on a packet to be forwarded. The system also has a second node coupled to the first node and to a number of ports. The second node has at least one table for specifying which of the ports are to receive the packet based on the filter values, and at least one table for accounting for egress traffic bandwidth.

  • Patent number: 9031070
    Abstract: Methods for controlling a Designated Forwarder (DF) election in a multicast network are described herein. The multicast network includes a plurality of multicast network devices, including a first network device and a second network device. A Designated Forwarder is determined. It is determined whether to initiate a Designated Forwarder election based on a comparison of a metric measuring a distance to a Rendezvous Point Address from a first network device and a metric measuring the distance to the Rendezvous Point Address from the second network device.

  • Publication number: 20150098318
    Abstract: An example method includes creating a plurality of redundant, non-looping paths to a plurality of switches, and providing information to the plurality of switches about the plurality of redundant, non-looping paths. The method further comprises assigning each of a plurality of clients to one of the plurality of redundant, non-looping paths, and providing information to the plurality of switches about which of the plurality of redundant, non-looping paths each client of the plurality of clients is assigned to. Then, in response to receiving a packet from a client of the plurality of clients, the method comprises transmitting the packet on one of the plurality of redundant, non-looping paths to one of the plurality of switches based at least in part on which of the plurality of redundant, non-looping paths the client is assigned to.

  • Publication number: 20150036502
    Abstract: A network, network devices, and methods are described for packet processing indication. A method includes tunneling a packet from a first network device to a second network device associated with a first checking functionality. The second network device has an address different than an original destination address of the packet. The method also includes return-tunneling the packet from the second network device to the first network device with an indication of whether the packet was processed by the first checking functionality. The method includes tunneling the packet from the first network device to a third network device associated with a second checking functionality in response to the indication being that the packet was not processed by the first checking functionality. The third network device has an address different from the original destination address of the packet.

  • Patent number: 8879563
    Abstract: A method includes reading content of network traffic that arrives at a network port of a network switch of a mesh of network switches. A hash algorithm is applied to the read content to indicate a path to a destination network switch of the mesh, the hash algorithm being common to all network switches of the mesh.

  • Patent number: 8594096
    Abstract: Dynamic hardware address assignment to network devices in a switch mesh is described. In an example, a network device in a switch mesh dynamically assigns a hardware address to a network interface. The network device receives an address request from a client through the switch mesh. The network device calculates an index value for the client based on data in the address request. The network device selects the hardware address of a plurality of hardware addresses assigned to the network interface based on the index value. The switch mesh includes a plurality of traffic paths respectively for the plurality of hardware addresses. The network device sends the hardware address in a reply to the client through the switch mesh.
