  • Faster fault-detection mechanism, for example using bidirectional forwarding detection (BFD), on network nodes and/or hosts multihomed using a link aggregation group (LAG)
    Patent number: 11349735
    Abstract: For use in a system including a first data forwarding device, a second data forwarding device, a third data forwarding device, a first communications link between the first data forwarding device and the second data forwarding device, and a second communications link between the first data forwarding device and the third data forwarding device, the first and second communications links belonging to a link aggregation group (LAG), a method includes (1) generating a message (i) for testing a first path between the first data forwarding device and the second data forwarding device, and a second path between the first data forwarding device and the third data forwarding device, and (ii) including an Internet protocol (IP) datagram including a multicast IP destination address and a payload containing path testing information; and (2) sending, over the LAG, the message from the first data forwarding device to both the second data forwarding device and the third data forwarding device.

  • Detecting link faults in network paths that include link aggregation groups (LAGs)
    Patent number: 10742488
    Abstract: A device may receive, from an ingress device, a packet for a protocol session associated with detecting faults in a path of a network that includes a link aggregation group (LAG). The packet may be encapsulated with a user datagram protocol (UDP) header that includes a dynamically assigned UDP source port identifier. The LAG may include a set of links. The device may select, using the dynamically assigned UDP source port identifier, a link in the LAG to use in the path. The device may provide, using the selected link, the packet to one or more downstream devices to permit a downstream device, of the one or more downstream devices, to determine whether packet timeout has occurred. The device may receive an instruction to maintain the protocol session or to close the protocol session and close the path. The device may provide the instruction to the ingress device.
