  • Publication number: 20230269270
    Abstract: The disclosed computer-implemented method includes applying transport protocol heuristics to selective acknowledgement (SACK) messages received at a network adapter from a network node. The transport protocol heuristics identify threshold values for operational functions that are performed when processing the SACK messages. The method further includes determining, by applying the transport protocol heuristics to the SACK messages received from the network node, that the threshold values for the transport protocol heuristics have been reached. In response to determining that the threshold values have been reached, the method includes identifying the network node as a security threat and taking remedial actions to mitigate the security threat. Various other methods, systems, and computer-readable media are also disclosed.

  • Patent number: 9118494
    Abstract: An apparatus comprising a proxy configured to couple to a sender and a receiver and to receive data from the sender at a first rate and forward the data to the receiver at a second rate that is less than the first rate. A method comprising detecting a reception speed for each of a plurality of receivers in a multicast group, assigning the receivers to a first group and a second group based on the reception speed of each of the receivers, wherein the first group has a reception speed that is faster than a reception speed of the second group, and sending multicast data intended for all of the receivers to the receivers in the first group and to a proxy at a first rate, wherein the proxy buffers the multicast data and sends the multicast data to the receivers in the second group at a second rate.
