# Network Engineering Roadmap from Beginner to Specialist.

Network Engineering Roadmap from Beginner to Specialist.

1. Networking Fundamentals:

* OSI and TCP/IP models
* Networking devices (routers, switches, hubs, bridges)

2. Network Protocols:

* Core protocols (TCP, UDP)
* Application layer protocols (HTTP, HTTPS, FTP, DNS, DHCP)
* Additional protocols (SNMP, ICMP, ARP)

3. Routing and Switching:

* Routing protocols (OSPF, EIGRP, BGP)
* Switching concepts (VLANS, STP, Trunking)
* Dynamic vs. static routing

4. Network Design and Architecture:

* Network topologies (star, mesh, bus, ring)
* Design principles (redundancy, scalability, reliability)
* Network types (LAN, WAN, MAN, WLAN, VLAN)

5. Network Security:

* Firewalls
* VPNs
* ACLs
* Security protocols (SSL/TLS, IPSec)
* Network security best practices

6. Wireless Networking:

* Wireless standards (IEEE 802.11a/b/g/n/ac/ax)
* Wireless network design (coverage, capacity planning)
* Wireless security (WPA2, WPA3)

7. Cloud Networking:

* Cloud networking services (VPC, Direct Connect, VPN)
* Hybrid cloud networking
* Cloud providers (AWS, Azure, Google Cloud)

8. Network Automation and Scripting:

* Automation techniques
* Scripting for network management (Python, Bash, PowerShell)

9. Monitoring and Troubleshooting:

* Network monitoring techniques (Ping, Traceroute, network diagrams)
* Performance monitoring (NetFlow, SNMP)
* Virtualization and container networking

10. Virtualization and Container Networking:

* Virtual network functions (NFV)
* Software-defined networking (SDN)
* 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)
