Layer 3

Within the seven-layer Open Systems Interconnection (OSI) model, Layer 3 is the network layer. Layer 3 is involved in the forwarding of incoming data packets of variable length. This network layer includes the functioning and procedures that

Fibre Uplink

Using a fibre uplink, one device can be connected to a network, or a LAN can be connected to a larger network. Switches, hubs and routers often have a specified port as the uplink connection. Switches with fibre uplink ports are a frequent

Network/Ethernet Switches

Ethernet switches physically connect devices on a computer network. They regulate data flow through the network by performing packet switching. A network switch will only broadcast a message to the device that requests or needs it. Each device
