Find the number of connections needed to be used in Mesh topology in network of 8 and also find that how many IO ports are needed for each device?

Find the number of connections needed to be used in Mesh topology in network of 8 and also find that how many I/O ports are needed for each device. Also write formulas used to solve this question?

Solution:

Formulas:

To find the no. of links:

= n (n-1)/2

To find the I/O ports:

= n-1

If the network of 8 then

No. of Links = n (n-1)/2

= 8(8-1)/2

=8(7)/2

=56/2

=28 ANS

No. of I/O ports: = n-1

=8-1

=7 ANS
