Study Notes
Network Hardware
- Patch Panel: Houses termination points for ethernet cables, simplifying device relocation.
- Router: Connects networks together, forwarding traffic leaving the internal network.
- Hub: Older device that broadcasts data to all connected devices, leading to network inefficiencies and security risks.
- Switch: Forwards data only to the intended device using MAC addresses, improving efficiency and security.
- Managed Switch: Allows advanced configuration options for bigger networks, including VLANs, QoS, and traffic monitoring.
- Firewall: Monitors and blocks unauthorized network traffic, improving security.
Power over Ethernet (PoE)
- PoE uses existing Ethernet cables to power devices by using spare wires.
- Standards: IEEE 802.3 defines several PoE standards, each offering different power levels and using specific wire pairs.
- Type 1 PoE (802.3af): Provides up to 15.4 watts, suitable for low-power devices.
- Type 2 PoE (802.3at): Provides up to 30 watts, compatible with Type 1 devices and suitable for mid-power devices.
- Type 3 PoE (802.3bt): Provides up to 60 watts, suitable for mid-range devices like webcams.
- Type 4 PoE (802.3bt): Provides up to 100 watts, suitable for demanding devices like laptops or TVs.
- PoE Injector: Allows powering devices over Ethernet even if the switch doesn't support PoE.
- Active PoE Injectors: Conform to PoE standards, protecting devices from incorrect power.
- Passive PoE Injectors: Don't conform to standards, potentially damaging devices.
Software-Defined Networking (SDN)
- SDN centralizes control of network resources using a controller, allowing for remote management and simplified configuration.
- It simplifies network management, facilitating quick changes, monitoring, and troubleshooting.
- SDN improves efficiency and security in increasingly complex modern networks.
