The Pcap transport handler is located in the Pcap Wrapper Feature.

The protocol itself

The source of this section is Wikipedia.

In the field of computer network administration, pcap (packet capture) consists of an application programming interface (API) for capturing network traffic. Unix-like systems implement pcap in the libpcap library; Windows uses a port of libpcap known as WinPcap.
Monitoring software may use libpcap and/or WinPcap to capture packets travelling over a network and, in newer versions, to transmit packets on a network at the link layer, as well as to get a list of network interfaces for possible use with libpcap or WinPcap.
The pcap API is written in C, so other languages such as Java, .NET languages, and scripting languages generally use a wrapper; no such wrappers are provided by libpcap or WinPcap itself. C++ programs may link directly to the C API or use an object-oriented wrapper.

Used library

This Odysseus feature uses pcapng-decoder.

Pcap protocol handler

In Odysseus, the output of the decoder is tranformed into a KeyValueObject that contains all available information. See the example below.

pcap_input := ACCESS({
                  transport = 'file',
                  protocol = 'pcap',
                  wrapper = 'GenericPull',
                  source = 'Pcap',
                  datahandler = 'keyvalueobject',
                  options = [
                    ['filename', 'somepcapfile.pcap']
