In a typical enterprise network architecture, the access layer switch is the first point of contact between end-user devices and the rest of the network. These switches connect endpoints such as PCs, printers, VoIP phones, and wireless access points, enabling user traffic to enter the LAN. It assists mainly in the switching of incoming and outgoing data packets to the right destination, as specified in MAC. In this layer, the layer 2 switches are installed to distribute the data packets to the addressed group of access devices. The layer 2 switches prevent over-crowding of data packets in transmission links and access devices. Wireless access points are also connected here and provide further access. FortiSwitch units distribute the ports to plugs. This layer serves as the network's outermost boundary and the gateway through which all data must pass. This layer is primarily composed of devices like access switches and wireless access points.

This is the most fundamental ring topology, formed by connecting three or more switches in a closed loop using fiber optic cables. Data can flow in either direction, allowing the network to recover quickly if a link fails. If you have multiple Ethernet switches that need to be connected over long distances, fiber is obviously a preferred choice. Moreover, when it comes to bandwidth, no currently available technology is better than single-mode fiber. It can provide significantly higher bandwidth and carry more data. A single 6 strand fiber can only connect 3 switches back to the core. How many switches do you plan to connect? A star is great for a limited number of switches. I have maybe 20 coming back to my cores. Rings are generally not done anymore, but I think that is for bandwidth as much as anything else. The mainline of the fiber optic LAN directly connects to the switch, then to the router. The connection between two or more Ethernet switches in a certain way (Uplink port, etc. ) is called the cascade. All switches have two fiber ports. Is the best way to have fiber backbone switch and connect fiber channel from every switch to the backbone? Or connect switch 1 to switch 2 to switch 3 to. switch 12 to switch 1 again? Thanks!
