About
Written by an industrial automation engineer who spent 4 months building an AI system from scratch (and documented every mistake along the way), this book bridges the gap between "I know networking" and "I automate networking."
What's Inside
Part I: AI Tools for Network Engineers
- Full 2026 comparison: Claude Code vs Cursor vs Copilot vs Windsurf vs Codex
- Benchmarks (LMSYS Arena, SWE-bench, Terminal-Bench) with links
- Pricing breakdown — one developer saved $15K vs API pricing
- Free & open-source tools: Ollama, n8n, CrewAI, LangChain, Dify
Part II: Network Automation Stack
- Python: Netmiko, NAPALM, Nornir (100x faster than Ansible)
- Ansible: 4 production-ready playbooks (backup, hardening, VLANs, provisioning)
- Terraform: AWS VPC, Palo Alto firewall examples
- Ollama: Run AI locally with zero cloud cost
Part III: Building an AI Expert (Genesis Project)
- Novel Cascade MoE architecture (patent filed May 2026)
- 10,800+ expert routes, 12,651 neurons, one-shot learning
- 14 documented mistakes with exact cost of each
Part IV: Enterprise Deployment
- Corporate network from scratch: DNS, DHCP, AD, firewall, VPN, monitoring
- Zero Trust architecture step-by-step
- SD-WAN vs MPLS migration strategy
- IPv6 transition guide
- Security automation: nftables, Suricata IDS, fail2ban, automated incident response
Part V: Real World
- 4 case studies (Princeton -95% time, Intel -70% incidents)
- 8 troubleshooting scenarios with diagnosis commands
- Network automation horror stories (real incidents)
- ROI calculator for management
- Free lab setup (Containerlab, GNS3, EVE-NG, Cisco DevNet Sandbox)
- 7 hands-on lab exercises
14 Mistakes I Made Building an AI for Network Automation
The most valuable chapter in the book — so you don't repeat them.
Mistake 1: Wrong Token IDs (Cost: 2 Days)
Model produced garbage during inference. BOS token ID was set to 1 (UNK) instead of 2. Lesson: Always verify special token IDs through server code, not documentation.
Mistake 2: Dataset Imbalance x25 (Cost: 10,000 Steps)
Model answered everything with "saving VPN passwords." One dataset (40 examples) was weighted x25 = 1,000 effective examples. Lesson: New datasets start at x10-15 max. No single category > 15%.
Mistake 3: Memory Pollution (Cost: Days)
Test runs filled memory.json (5.2 MB) with garbage, injected into every prompt. Lesson: Clear runtime files before every test.
Mistake 4: Full Backup Restore — THE BIG ONE (Cost: $100 + 90K Steps)
Instead of fixing one broken line, restored ENTIRE file from month-old backup. Missing 100+ datasets, correct multipliers, critical fixes. Quality dropped 95% → 15%.
Lesson: NEVER restore from old backups. Fix the specific line. cp file file.pre_edit before any edit.
Mistake 5: "Wait and See" Mentality (Cost: Weeks)
Lesson: See a problem? Act IMMEDIATELY. Never "wait and check later."
...and 9 more mistakes in the full book.
Quick Start: Your First Network Automation
# Install tools
pip install netmiko ansible
npm install -g @anthropic-ai/claude-code
# Connect to a Cisco switch with Python
python3 << 'EOF'
from netmiko import ConnectHandler
device = {
'device_type': 'cisco_ios',
'host': '192.168.1.1',
'username': 'admin',
'password': 'secret',
}
conn = ConnectHandler(**device)
print(conn.send_command('show ip interface brief'))
conn.disconnect()
EOF
# Or use AI to generate an Ansible playbook
claude "Write an Ansible playbook to configure VLANs 10,20,30
on Cisco switches with trunk ports on Gi0/1"
