  • Pseudowire circuit emulation
    Patent number: 9037746
    Abstract: A method includes establishing a first pseudowire between a first switching device and a second switching device. The method also includes receiving customer traffic that includes time division multiplexed data and formatting the time division multiplexed data as packets. The method further includes identifying a destination for the customer traffic, identifying the first pseudowire for forwarding the customer traffic and forwarding the customer traffic via the first pseudowire to the second switching device.
    Type: Grant

  • Monitoring link aggregation links
    Patent number: 8630188
    Abstract: A device detects a signal condition for a link aggregation group (LAG) link, compares the detected signal condition to a signal threshold range, and enables one of a disabled state or a disabled timer state for the LAG link if the detected signal condition is outside the signal threshold range.
    Type: Grant

  • Link aggregation
    Patent number: 8565085
    Abstract: A disclosed method and device relate to defining a link aggregation group (LAG) media access control (MAC) address and assigning the LAG MAC address to two or more links to define a LAG. The LAG MAC address does not duplicate physical MAC addresses associated with the links in the LAG. Datagrams associated with the links in the LAG are routed based on the LAG MAC address.

  • Disabled state and state signaling for link aggregation
    Patent number: 8437262
    Abstract: A device enables a disabled timer state for a link aggregation group (LAG) link if a disabled timer condition is determined for the LAG link, and enables a disabled state for the LAG link if a disabled condition is determined for the LAG link in the disabled timer state.
