Network Engineering Roadmap

A personal 4–6 month plan to reach my goal in network infrastructure and operations

Network Engineering Study Plan

A comprehensive guide to network engineering roles

Phase 1: Core Foundations (Weeks 1–4)

Networking Basics

  • TCP/IP, IPv4/IPv6, Routing (BGP, OSPF)
  • Switching, VLANs, NAT, DHCP, DNS
  • Common network tools: ping, traceroute, nslookup, netstat, tcpdump

Tools & Certifications

  • Tools: Cisco Packet Tracer, GNS3, Wireshark
  • Certs: CompTIA Network+, Cisco CCNA (start here)

Phase 2: Intermediate Networking + Infrastructure (Weeks 5–8)

Infrastructure Setup & Troubleshooting

  • Fiber optics, Cat5e/Cat6/Cat6a, patch panels
  • Labeling, testing (Fluke tester), continuity checks
  • Install cable trays, racks, crimping, RF basics

Hands-on & Certifications

  • Hands-on: Set up home lab with real cable installs (or simulate)
  • Certs: BICSI INST1/INSTC, FOA CFOT (optional)

Phase 3: Systems + Scripting (Weeks 9–12)

Sysadmin & Scripting

  • Linux CLI, user management, networking configs
  • Basic scripting in Python, Bash, simple automation tasks
  • SQL basics (for logs, monitoring data)

Tools & Resources

  • Tools: Ubuntu VM, VS Code, Git, SQLite
  • Resources: OverTheWire (Linux), HackTheBox (NOC-style labs)

Phase 4: Advanced Network Concepts (Weeks 13–16)

Service Provider & Enterprise Networking

  • MPLS, IS-IS, peering, BGP multi-homing
  • Internet services: DNS, DHCP, NTP in-depth
  • POPs, colocation, DWDM, optics troubleshooting

Certifications

  • Cisco CCNP, Juniper JNCIA-Junos (optional)

Phase 5: Ops, Monitoring & Real-Time Systems (Weeks 17–20)

NOC/SOC Operations

  • Incident handling, triage, escalation process
  • Using Zabbix, Grafana, or Prometheus for network monitoring
  • Working in on-call rotations, ticketing (e.g., ServiceNow)

Simulation

  • Create NOC dashboards with dummy logs and alarms

Absolute Must-Haves (for all 3 roles):

  • 1+ year experience in NOC/IT/Security
  • Networking protocols: TCP/IP, BGP, OSPF, IPv6
  • Linux CLI + basic scripting (Python/Bash)
  • Troubleshooting skills (cables, systems, protocols)
  • Familiarity with DNS, DHCP, NAT, NTP, WiFi, Ethernet
  • Certs: CompTIA Net+, Cisco CCNA (at least)

Tools to Use Throughout

  • GNS3 / EVE-NG for labbing BGP/MPLS scenarios
  • Wireshark for packet analysis
  • Home server or Raspberry Pi for lab environments
  • Cloud VMs (AWS/GCP free tier) to simulate network designs
