Networking
Understanding and applying the principles, protocols, technologies, and architectures used to connect computers and devices to enable communication and data sharing. (More fundamental).
Proficiency Level
Level 1 (Follow)
- Understands basic networking concepts like IP addresses, subnets, gateways, and the difference between LAN and WAN.
- Follows instructions for simple network-related tasks such as connecting a computer or printer to the network correctly.
- Can describe the basic function of common network devices like routers and switches.
Level 2 (Assist)
- Assists in performing basic network configuration tasks on end-user devices (e.g., setting static IP addresses, configuring Wi-Fi settings).
- Helps troubleshoot simple network connectivity problems using standard command-line tools (e.g., ping, ipconfig/ifconfig, tracert).
- Understands the layers of the OSI or TCP/IP model at a basic level.
Level 3 (Apply)
- Applies solid knowledge of core networking protocols (TCP/IP suite including DNS, DHCP) and technologies (Ethernet, Wi-Fi standards) to configure and troubleshoot network connectivity for servers, workstations, and basic infrastructure.
- Understands basic switching concepts (VLANs, MAC addresses) and routing concepts (static routes, default gateways).
- Can interpret network diagrams and documentation to understand network topology.
Level 4 (Ensure)
- Applies deep understanding of advanced networking protocols (e.g., BGP, OSPF), complex routing and switching techniques, network addressing schemes (IPv4, IPv6), and network architectures (e.g., three-tier, spine-leaf).
- Diagnoses complex network performance issues involving latency, jitter, and packet loss.
- Understands network security principles and how they integrate with network design.
Level 5 (Strategise)
- Leverages expert knowledge of current and emerging networking principles, technologies (e.g., SDN, NFV, cloud networking), and architectures to inform strategic network design and evolution.
- Understands the critical interplay between network design choices and application performance, security posture, and overall business capabilities.
- Contributes to the development of organisational networking standards and best practices.
