Arranging Mesh Topology required cables

A fully connected mesh network has n (n-1)/2 physical channels to link n devices. Every device on the network must have n-1 input/output ports.

• Number of cable= n (n-1)/2 = 6(6-1)/2= 15
• Number of ports per device = n-1= 6-1= 5

So 15 cables and 5 ports, per device are needed to arrange six devices in mesh Topology.

Arranging Mesh Topology required cables

Generally, the number of cables needed to connect all the devices in a fully connected mesh network can be written as, n (n-1)/2.

When the total number of network devices in the network is 6, simply we can substitute n with 6. Then number of cables required is equal to 6(6-1)/2.

The answer is 15 cables.

The number of ports needed by each device becomes 5, as the device needs to connect with all other 5 devices in the network.

If it is a half meshed network, the number of cables and ports required is less.

Hope your problem is solved.
