The dataset then is split into DATA ( srt.iscontrol = 0) and CONTROL ( srt.iscontrol = 1) packets.The data is filtered to extract SRT packets only ( ws.protocol = SRT), which makes sense for further analysis.This data is further cleaned and transformed using pandas in the following way: csv format with timestamp, source IP address, destination IP address, protocol, and other columns and rows representing observations (sent/received packets). pcap(ng) trace file with measurements from a specific network interface and port collected at the sender/receiver side is used as a proxy for packet data collected by SRT. overwrite / -no-overwrite If exists, overwrite the. Īs soon as the library is installed, you can run modules directly: For regular installation, use pip install. This allows changing the source code (both tests and library) and rerunning tests against library code at will.

install the library in “editable” mode by running pip install -e.

This ensures the code and dependencies are isolated from the system Python installation,

use venv for virtual environments and pip for installing the library and any dependencies.

tshark 3.2.2+ (setting up tshark is described here and in the SRT CookBook here).

To support several data flows adjustments will be required. Important: Currently, trace files containing only one flow of data are supported. See the get-traffic-stats script for details and report examples.

the number of SRT DATA and CONTROL packets present in a dump,.In particular, the following statistics are calculated at the receiver side: It also helps to process a network trace file and generate a report with SRT related statistics. pcap(ng) tcpdump or Wireshark trace files and extract SRT packets of interest for further analysis. Lib-tcpdump-processing is a library designed to process.
