I am in the process of restructuring our network infrastructure with the new design . what is the best standard approach to have redundancy in mind <br />
<br />
10 story building with 3 columns . Our IT room located in the 4th floor and having two manage high end switches in the core level . second one is not live but it has the same configuration . most of the floor are having fiber single core ones . one of my friend told me to go with 2 or 4 core to have redundant . I did not understand the redundancy with one cable with 2 0r 4 core one will help .I got to know is batter to have two cables fiber connection to each floor and then distribute within the floor .<br />
please advice me on the best practice on the above implementation .

Standard network Setup

Networking hardware includes the physical devices facilitating the use of a computer network. Typically, networking hardware includes gateways, routers, network bridges, modems, wireless access points, networking cables, line drivers, switches, hubs, and repeaters. But it also includes hybrid network devices such as multilayer switches, protocol converters, bridge routers, proxy servers, firewalls, network address translators, multiplexers, network interface controllers, wireless network interface controllers, ISDN terminal adapters and other related hardware.
