| |
Its just for an idea. Do it your self.
Question 1:
For each of the f ollowing f our networks, discuss the consequences if a connection f ails. [10
marks]
a. Fiv e devices arranged in a mesh topology
b. Fiv e devices arranged in a star topology (not counting the hub)
c. F iv e devices arranged in a bus topology
d. Fiv e devices arranged in a ring topology
Solution:
a. Five devices arranged in a mesh topology
In mesh topology each device has a dedicated point-to-point link with another device. A devic e in
mesh topology must have n-1 connection. If a connection fails it does not eff ect to entire
network.
n=5
5(5-1)/2
25-5/2
20/2 =10
If one device is f ail then
Remaining devices are 4
n=4
4(4-1)/2
12/2 =6
b. Five devices arranged in a star topology (not counting the hub)
In star topology each dev ice has a dedicated point-to-point link with a central hub. Hub prov ide link
between all dev ices which are attach to it. I f one dev ice is f ail out of f ive then the whole network
is not eff ected.
c. Five devices arranged in a bus topology
bus topology is Multipoint. One long cable acts as a Backbone to link all dev ices in the network.
