WebInside the packet processing function Snort performs several tasks. First, it calls into libpcap using the pcap_dispatch function to process any waiting packets. For each packet that is available, libpcap calls the PcapProcessPacket function (src/snort.c: 1167), which handles the actual packet processing. This function resets several per-packet counters, … WebDec 10, 2012 · Click on image to enlarge. An ASF implementation can be divided into three components: 1. ASF packet engine: An actual data-packet processor that closely interacts with network and security drivers for packet handling and processing. 2. ASF configuration APIs: To configure the control information in ASF packet engine. The purpose of these …

Packet processing delay is a constant amount of delay faced at both the source and the destination. At the source, this delay might include the time taken to convert analog data to digital form and packetize them through different layers of protocols until data are handed over to the physical layer for transmission.
