Network Simulation Skill

Expert skill for network condition simulation, emulation, and chaos engineering testing environments.

Capabilities

  • Traffic Control: Configure tc (traffic control) for latency, bandwidth, and packet loss simulation
  • Network Namespaces: Set up network namespaces for network isolation testing
  • WAN Emulation: Emulate WAN conditions with netem (delay, jitter, loss, corruption)
  • Virtual Topologies: Create virtual network topologies for testing
  • Packet Manipulation: Simulate packet loss, reordering, duplication, and corruption
  • Degraded Conditions Testing: Test applications under degraded network conditions
  • Chaos Scenarios: Generate chaos engineering scenarios for resilience testing
  • Container Networking: Configure Docker/Kubernetes network simulation

Tools and Dependencies

  • tc - Traffic control for Linux
  • netem - Network emulator
  • ip netns - Network namespaces
  • mininet - Network emulator
  • toxiproxy - TCP proxy for chaos testing
  • comcast - Network simulation tool
  • pumba - Container chaos testing

Target Processes

  • network-testing-framework.js
  • load-testing-tool.js
  • protocol-fuzzer.js
  • tcp-socket-server.js

Usage Examples

Latency Simulation

tc qdisc add dev eth0 root netem delay 100ms 20ms distribution normal
tc qdisc change dev eth0 root netem delay 200ms 40ms 25% correlation

Packet Loss Simulation

tc qdisc add dev eth0 root netem loss 5% 25%
tc qdisc add dev eth0 root netem loss gemodel 1% 10% 70% 0.1%

Bandwidth Limiting

tc qdisc add dev eth0 root tbf rate 1mbit burst 32kbit latency 400ms

Network Namespace Isolation

ip netns add test_ns
ip link add veth0 type veth peer name veth1
ip link set veth1 netns test_ns
ip netns exec test_ns ip addr add 10.0.0.2/24 dev veth1
ip netns exec test_ns ip link set veth1 up

Toxiproxy Chaos

toxiproxy-cli create -l localhost:6379 -u localhost:6380 redis_proxy
toxiproxy-cli toxic add -t latency -a latency=1000 redis_proxy

Quality Gates

  • Network conditions applied correctly
  • Application behavior under degraded conditions verified
  • Chaos scenarios executed successfully
  • Recovery testing completed
  • Performance baselines established
