Custom topology creation: using Mininet CPI

a$.$ Create the above topology in Mininet.

b$.$ Test the network.

i$.$ Dump the connections.

ii$.$ Test reachability of all the connections

c$.$ Finally terminate the network

d$.$ What would be the outcome of the reachability test if there was no link between s$1$ and

s$2?$

e$.$ Would there be any difference in the outcome if you replaced the OpenFlow switches

with legacy switches? Why? Why not?

$2.$ Custom topology with performance parameters:

a$.$ Reuse the previous topology and create the hosts and links with the following

constraints

i$.$ Hosts $$ h$2$ and h$3$ gets $50\%$ of system CPU power.

ii$.$ All link constraints $$ Bandwidth of $10$Mbps$,$ delay of $5$ms$,$ loss of $2\%$ and

maximum queue size of $1000$

b$.$ Test the connection speeds between the following hosts.

i$.$ h$1$ and h$2$

ii$.$ h$1$ and h$3$

iii. h$2$ and h$3$

iv$.$ h$1$ and h$4$

$3.$ Explain briefly outcomes you got from the speed tests in question $2.$b by comparing the

corresponding throughputs.

$4.$ What difference would it make in the speed test if the links between all $4$ hosts and their

corresponding switches were defined using the same parameters? $($Show with evidence$)$
