Abstract

A traffic anomaly detector of a Peripheral Component Interconnect express (PCIe) system, including filters configured to filter headers of PCIe transaction layer packets (TLPs) based on respective filter criterion; a classifier configured to trigger an event based on one of the filter criterion or a logical combination of a plurality of the filter criteria; an event counter configured to count a number of the events; and a processor configured to detect, based on a value of the event counter, an anomaly in the PCIe TLP traffic.
