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)

1. Network Protocols:

• Core protocols (TCP, UDP)

• Application layer protocols (HTTP, HTTPS, FTP, DNS, DHCP)

• Additional protocols (SNMP, ICMP, ARP)

1. Routing and Switching:

• Routing protocols (OSPF, EIGRP, BGP)

• Switching concepts (VLANS, STP, Trunking)

• Dynamic vs. static routing

1. Network Design and Architecture:

• Network topologies (star, mesh, bus, ring)

• Design principles (redundancy, scalability, reliability)

• Network types (LAN, WAN, MAN, WLAN, VLAN)

1. Network Security:

• Firewalls

• VPNs

• ACLs

• Security protocols (SSL/TLS, IPSec)

• Network security best practices

1. Wireless Networking:

• Wireless standards (IEEE 802.11a/b/g/n/ac/ax)

• Wireless network design (coverage, capacity planning)

• Wireless security (WPA2, WPA3)

1. Cloud Networking:

• Cloud networking services (VPC, Direct Connect, VPN)

• Hybrid cloud networking

• Cloud providers (AWS, Azure, Google Cloud)

1. Network Automation and Scripting:

• Automation techniques

• Scripting for network management (Python, Bash, PowerShell)

1. Monitoring and Troubleshooting:

• Network monitoring techniques (Ping, Traceroute, network diagrams)

• Performance monitoring (NetFlow, SNMP)

• Virtualization and container networking

1. Virtualization and Container Networking:

• Virtual network functions (NFV)

• Software-defined networking (SDN)

• Container networking (Docker, Kubernetes)

1. Certifications:

• Entry-level (CompTIA Network+, Cisco CCNA)

• Professional-level (Cisco CCNP, Juniper JNCIP)

• Advanced-level (Cisco CCIE, VMware VCP-NV)
