Dataset Summary

MalayaNetwork_GT is a private network traffic dataset captured from several real network environments and multiple time windows to intentionally introduce non-IID characteristics. This repository contains:

• Raw packet captures (PCAP/): .pcapng files (approximately 35GB total in the full dataset).
• Derived flow features (csv_output/): flow-based CSVs extracted using CICFlowMeter (CSV size varies depending on capture duration and traffic volume).

In this repo snapshot, there are 10 application/service classes (one folder per class).

Motivation

Many public network-traffic datasets (e.g., ISCX-VPN2016) can be outdated and may not reflect the non-IID nature of traffic seen in real deployments. For network traffic, non-IID commonly means the data distribution is not uniform across classes, environments, or time. For example, some traffic patterns appear only in certain environments or times of day.

This matters especially for distributed learning settings such as Federated Learning (FL), where statistical heterogeneity can degrade convergence speed and model accuracy if clients observe substantially different traffic distributions.

Dataset Creation

Data collection

Traffic was captured using Wireshark from a network interface with promiscuous mode enabled to capture all frames (useful especially on wireless networks).

To encourage non-IID characteristics, captures were performed over a three-month period at different times of day:

• Morning: 9-10 AM
• Peak hours: 12-1 PM
• Non-peak/night: 8-9 PM

This introduces temporal heterogeneity (and potential concept drift): the same label may exhibit different feature distributions depending on time-of-day usage patterns.

Additionally, traffic was collected from several network environments, contributing to covariate shift between subsets (e.g., different user behavior and usage patterns across environments such as campus networks vs public Wi‑Fi vs home broadband vs mobile networks).

To minimize background traffic and support anonymity, we used the following methods:

• Dedicated virtual machines per application/service.
• Pseudo user accounts for registration where needed.
• Background noise reduction by removing bloatware, disabling automatic updates, and stopping non-essential processes.

Most services used TLS-encrypted payloads. BitTorrent may include unencrypted peer communications depending on peers and client behavior.

Feature extraction

Packet captures (.pcapng/.pcap) were transformed into flow-based features using CICFlowMeter by Canadian Institute for Cybersecurity (CIC). The resulting CSVs include per-flow fields such as IP/ports/protocol, timestamps, flow duration, byte/packet rates, IAT statistics, packet length statistics, TCP flag counts, active/idle stats, and subflow aggregates. Most of these services encrypted their communication payload via TLS, with the exception of BitTorrent. Although BitTorrent clients such as Q-BitTorrent enabled encryption by default, not all P2P peers supported encrypted communication.

Dataset Structure

Repository layout

• PCAP/: raw captures grouped by class (subfolders contain .pcapng/.pcap)
  • Example: PCAP/Zoom/Zoom_5G_Daytime1.pcapng
• csv_output/: flow-feature CSV outputs (mirrors the class folder structure)
• cicflowmeter_batch.sh: batch runner to process each immediate subfolder under PCAP/. Used for reproducing the the csv outputs.

Application/Service classes in this repo

• Bittorent
• ChromeRDP
• Discord
• EA Origin
• Microsoft Teams
• Slack
• Steam
• Teamviewer
• Webex
• Zoom

Example file naming convention

Files commonly encode environment and time window, e.g.:

• Zoom_5G_Daytime1.pcapng / Zoom_5G_Daytime1.csv
• Steam_Campus_Daytime1.pcapng / Steam_Campus_Daytime1.csv
• Webex_HomeBroadband_Daytime1.pcapng / Webex_HomeBroadband_Daytime1.csv

Intended Uses

• Network Traffic classification across application/service classes using flow features.
• Non-IID / FL evaluation

Limitations

• Non-IID by design: results may differ significantly depending on how you split data (by environment, time, capture session).
• Dataset size:
  • PCAPs are ~35GB for the full dataset (private); CSV size depends on extracted flows and can vary widely.
• Privacy: raw captures and derived flows may include IP addresses and ports. This repo does not claim anonymization; treat the data as potentially sensitive.

How to reproduce the CSVs (CICFlowMeter)

Prerequisites

• Python: 3.12+
• CICFlowMeter: via Python dependency cicflowmeter
• Installs may require system libpcap and tcpdump packages via apt/pacman/etc.

Install

This repo includes pyproject.toml, so you can install dependencies with either uv or pip.

• Using uv:

uv sync

• Using pip:

pip install -r requirements.txt

Generate CSVs from all folders in PCAP/ using the batch script

Run CICFlowMeter once per subfolder under PCAP/ and write outputs to csv_output/<folder>/:

./cicflowmeter_batch.sh -i ./PCAP -o ./csv_output

If you prefer a single combined CSV output directory:

./cicflowmeter_batch.sh -i ./PCAP -o ./csv_output --flat

Generate CSVs from a single folder using CICFlowMeter directly

cicflowmeter -d "./PCAP/Zoom/" -c "./csv_output/Zoom/"
