  • Patent number: 9755939
    Abstract: In one embodiment, a method includes generating at a network device, a trace packet comprising an IP (Internet Protocol) to Source Group Tag (SGT) binding, transmitting the trace packet from the network device to an SGT capable device, wherein at least one non-SGT capable device is interposed in a path between the network device and the SGT capable device, and receiving at the network device, a reply packet from the SGT capable device in response to the trace packet, the reply packet indicating that the IP to SGT binding was installed at the SGT capable device. An apparatus and logic are also disclosed herein.
    Type: Grant

  • Patent number: 8363556
    Abstract: Systems, methods and other embodiments associated with dynamic probe generation are described. In one embodiment, an apparatus includes generation logic to dynamically generate a probe configured to identify a status associated with an event occurring in a network device, a path between network devices, and/or a location in an encapsulation stack. Additionally, the apparatus comprises reception logic to receive the status.

  • Patent number: 8250359
    Abstract: A packet forwarding process, on a data communications device, forwards a packet to a plurality of destinations within a network from that data communications device using an “encrypt, then replicate” method. The packet forwarding process receives a packet that is to be transmitted to the plurality of destinations, and applies a security association to the packet using security information shared between the data communications device, and the plurality of destinations, to create a secured packet. The secured packet contains a header that has a source address and a destination address. The source address is inserted into the header, and then the packet forwarding process replicates the secured packet, once for each of the plurality of destinations. After replication, the destination address is inserted into the header, and the packet forwarding process transmits each replicated secured packet to each of the plurality of destinations authorized to maintain the security association.
