SYSTEMS & NETWORK ENGINEERING · ARCHITECTURE SHOWCASE

OpenWrt WiFi Quota & Bandwidth Manager

Beyond conventional application development, this systems project bridges low-level router firmware, Linux kernel packet filtering, background daemon communications, and a mobile management controller.

System Component Hierarchy & Data Flow

Verified Repository Architecture
LAYER 01

OpenWrt Router OS

Linux Kernel • iptables • tc
  • • iptables: Byte quota accounting chains per client IP/MAC.
  • • Traffic Control (tc): HTB rate limiting on eth0/wlan0.
  • • UCI Configuration: Interface isolation and guest network rules.
Status: Implemented in Firmware
LAYER 02

Network & Hardware

Interfaces • Telemetry
  • • Hardware I/O: Microcontroller status interfaces & LEDs.
  • • Interface Metering: Periodic byte stream counting without packet drop.
  • • Hardware Health: Router CPU load and memory state monitoring.
Status: Hardware Integration Tested
LAYER 03

Node.js Daemon

Background Service • Sockets
  • • Daemon Loop: Reads kernel quota counters via child process calls.
  • • Quota Enforcement: Triggers throttle or cut-off rules upon limit breach.
  • • WebSocket Bridge: Low-overhead local bridge stream to client.
Status: Implemented Daemon
LAYER 04

Flutter Mobile App

Controller • Clean Architecture
  • • Telemetry Gauges: Real-time visualization of bandwidth usage.
  • • Device Management: View active leases, trigger disconnects.
  • • Clean Architecture: Separation of UI, domain logic, and socket repos.
Status: Application Prototype

System Boundaries & Implementation Details

System Purpose: Provide small-to-medium network operators and administrators with granular, router-native quota monitoring and bandwidth control without expensive proprietary hardware.
My Implementation Responsibilities: Configured OpenWrt Linux firmware routines, crafted custom iptables quota accounting scripts, built the Node.js background communication service, and programmed the Flutter mobile controller UI.
Implemented vs. Experimental Capabilities: • Implemented: Router iptables quota accounting, shell daemon routines, Node.js WebSocket socket bridge, Flutter mobile management dashboard.
• Planned / Experimental: Cloud-based multi-router fleet synchronization and automated captive portal guest vouchers.

# 2. Insert quota match rule for client IP
$IPT -I FORWARD -s $CLIENT_IP -m quota \

# 3. Shape bandwidth ceiling with tc queueing
tc qdisc add dev br-lan root handle 1: htb default 12
tc class add dev br-lan parent 1: classid 1:1 htb rate 50mbit

# 4. Stream status to local Node.js daemon socket
echo "QUOTA_SET:$CLIENT_IP:$QUOTA_BYTES" | nc -U /var/run/quota.sock
