    Abstract: The present disclosure relates to a system, a method, and a non-transitory computer readable storage medium for deep packet inspection scanning at an application layer of a computer. A method of the presently claimed invention may scan pieces of data received out of order without reassembly at an application layer from a first input state generating one or more output states for each piece of data. The method may then identify that the first input state includes one or more characters that are associated with malicious content. The method may then identify that the data set may include malicious content when the first input state combined with one or more output states matches a known piece of malicious content.

  • Publication number: 20200336934
    Abstract: A method for transmitting a resource request for an uplink (UL) multi-user (MU) transmission is described. A High Throughput (HT) Control field that includes buffer information corresponding to media access control (MAC) protocol data units (MPDUs) that are queued for transmission by a first communication device is generated by the first communication device. The buffer information indicates a number of bytes for the MPDUs that are queued for transmission. A resource request MPDU that includes the HT Control field is generated by the first communication device. The resource request MPDU is transmitted by the first communication device to a second communication device via a wireless communication channel to request an allocation of radio resources for the UL MU transmission by the second communication device.
