Roadmap to learn Network Engineering

Here's a comprehensive guide to mastering the essential skills and knowledge areas:

1. Networking Fundamentals: OSI model, TCP/IP model, and networking devices (routers, switches, hubs, bridges).

2. Network Protocols: Core protocols (TCP, UDP, IP), application layer protocols (HTTP, HTTPS, FTP, DNS, DHCP), and additional protocols (SNMP, ICMP, ARP).

3. Routing and Switching: Routing protocols (OSPF, EIGRP, BGP), switching concepts (VLANs, STP, trunking), and routing techniques.

4. Network Design and Architecture: Network topologies (star, mesh, bus, ring), design principles (redundancy, scalability, reliability), and network types (LAN,
WAN, MAN, WLAN, VLAN).

5. Network Security: Firewalls, VPNs, ACLs, security protocols (SSL/TLS, IPSec), and best practices.

6. Wireless Networking: Wireless standards (IEEE 802.11a/b/g/n/ac/ax), wireless security (WPA2, WPA3), and network design.

7. Cloud Networking: Cloud services (VPC, Direct Connect, VPN), hybrid cloud Networking, and cloud providers (AWS, Azure, Google Cloud).

8. Network Automation and Scripting: Network programmability, automation techniques, and scripting (Python, Bash, PowerShell).

9. Monitoring and Troubleshooting: Network monitoring, troubleshooting techniques (ping, traceroute, network diagrams), and performance monitoring (NetFlow, SNMP).

10. Virtualization and Container Networking: Virtual network functions (NFV), software-defined networking (SDN), and container networking (Docker, Kubernetes).

11. Certifications: Entry-level (CompTIA Network+, Cisco CCNA), professional-level (Cisco CCNP, Juniper JNCIP), advanced-level (Cisco CCIE, VMware VCP-NV).
