  • Patent number: 11165818
    Abstract: Aspects of the present disclosure involve systems, methods, computer program products, and the like, for utilizing an access log of a proxy server device of a content delivery network (CDN) to detect and mitigate a denial of service (DOS) on a web or content server hosted by the CDN. Through an analysis of the content requests received at the proxy server listed in the access logs, one or more IP addresses may be identified as involved in a potential DOS attack or other suspicious behavior. Once identified, the suspicious activities of the one or more IP addresses may be tracked and aggregated over a particular period of time, with each detected suspicious request to the content server being counted. The count of suspicious requests to the content server may then be compared to one or more threshold values and a remediation action may occur when the thresholds are met or exceeded.

  • Publication number: 20210337413
    Abstract: The disclosed technology addresses the problem of testing performance of RU scheduling algorithms used by an OFDMA enabled AP to support multiple clients, using a two-armed test harness with a wired connection to one side of an AP under test and multiple wireless clients coupled in RF communication with the AP. The wireless clients can be connected over the air or conductively to antenna(s) of the AP under test. The test harness generates test traffic. A sniffer radio listens to RU allocation and schedules traffic broadcast by the AP to multiple clients. A recording module records the RU allocation and traffic and a report generator categorizes the recorded resource allocation with the scheduling traffic heard by the sniffer radio and provides resource allocation statistics. The wireless clients are connected conductively or OTA to antennas of the AP under test. One sniffer radio replaces multiple sniffers used in prior test systems.
