  • Patent number: 11729085
    Abstract: A method and system for packet tracing is described. In one embodiment, a method includes selecting a packet for tracing through a cluster of a plurality of nodes. The method includes preparing the packet for tracing by generating a cluster-wide unique ID, associating the unique ID with the packet, generating a running counter, and associating the counter with the packet. The method includes generating a first record buffer on a first node of the plurality of nodes and recording the unique ID and an initial value of the counter. The method includes recording a description of an operation performed on the packet in the first record buffer along with a value of the counter. The method also includes transferring the packet to a second node, along with the unique ID, the value of the running counter, and an attribute that indicates that the packet is to be traced.

  • Publication number: 20210105219
    Abstract: In one embodiment, a network security device configured to monitor a communication session between a first device and a second device generates a first empty acknowledgment packet specifying a first sequence number and sends the first empty acknowledgment packet to the first device. The network security device may thereafter determine that a response from the first device has not been received within a threshold amount of time and generate, at least partly in response, a second empty acknowledgment packet specifying a second sequence number. The network security device may send the second empty acknowledgment packet to the first device and receive, from the first device, a third empty acknowledgment packet specifying a third sequence number. The network security device may then store the third sequence number in association with the communication session between the first device and the second device.

  • Patent number: 10913879
    Abstract: Provided herein are thermally conductive underfill compositions which have a combination of melt viscosity, glass transition temperature (Tg), coefficient of thermal expansion, and/or transparency that renders such materials useful for the preparation of a variety of electronic devices, such as flip chip packages, stacked dies, hybrid memory cubes, through-silica via (TSV) devices, and the like. In certain embodiments of the invention, there are provided assemblies comprising a first article permanently adhered to a second article by a cured aliquot of a formulation as described herein. In certain embodiments of the invention, there are provided methods for adhesively attaching a first article to a second article. In certain embodiments of the present invention, there are provided methods for improving heat dissipation by electronic devices assembled employing thermally conductive, but electrically non-conductive adhesive.

  • Patent number: 10104002
    Abstract: In one embodiment, a method is described. The method includes receiving a network communication from a source device (where the network communication is received at a network device, and the network communication comprises a sequence number) and determining whether the sequence number is to be modified. In response to a determination that the sequence number is to be modified, the method further includes extracting the sequence number from the network communication, modifying (by a processor of the network device) the sequence number to produce a modified sequence number, and inserting the modified sequence number in the network communication, in place of the sequence number, to produce a modified network communication. Further still, the method includes transmitting the modified network communication to a destination device, where the network communication is transmitted from the network device.
