Methods and systems for non-intrusive debug processing of network frames

A system for network frame processing, comprising

• a network interface configured to receive network communications and to output frames associated with the network communications;
• a key generation engine configured to receive a frame from the network interface and to generate a normal key and a debug key for the received frame;
• frame classification logic configured to compare the normal key to classification reference data and to generate a frame classification for the received frame;
• debug comparison logic configured to compare the debug key to debug reference data and to generate one or more debug markers for the received frame, the debug comparison logic being configured to operate concurrently with the frame classification logic;
• frame marking logic configured to receive the frame classification and the one or more debug markers, to classify the received frame with the frame classification, and to mark the received frame with the one or more debug markers;
• and
• a frame processing engine configured to use the frame classification and the one or more debug markers to process the received frame in parallel according to the frame classification and the one or more debug markers.
