Edge Simulator & Emulator

Learn how to simulate edge computing environments locally for development and testing purposes.

Network Simulation​

Bandwidth Limiting​

# Install traffic control tools
sudo apt-get install iproute2

# Limit bandwidth to simulate edge conditions
sudo tc qdisc add dev eth0 root handle 1: tbf rate 1mbit burst 5kb latency 70ms

Latency Simulation​

# Add network delay
sudo tc qdisc add dev eth0 root netem delay 100ms 20ms distribution normal

Resource Constraints​

Docker Resource Limits​

# Run container with edge-like constraints
docker run --memory=512m --cpus=0.5 myapp:latest

Kubernetes Edge Simulation​

apiVersion: v1
kind: Node
metadata:
  name: edge-simulator
  labels:
    node-role.kubernetes.io/edge: "true"
spec:
  capacity:
    cpu: "2"
    memory: "2Gi"
    storage: "20Gi"

Best Practices​

  1. Realistic Constraints: Use actual edge device specifications.
  2. Network Simulation: Test under various connectivity conditions.
  3. Failover Testing: Simulate connectivity loss scenarios.
  4. Performance Monitoring: Track resource usage patterns.
