This assignment will be posted on blackboard also and instructions will be given on blackboard to enter the required answers. Please, see instructions of each questions as student number is represented as $12345789$ in $1$st question and in the form of A and B in $2$nd and $3$rd question. Submit a hard copy on due date and also upload a copy on blackboard.

Assignment

$1.$ Find the shortest distance from S to E on the network below. $[40]$

The cost between node S and node A is $-1$st number of your student number.

The cost between node A and node B is $-2$nd number of your student number.

The cost between node A and node C is $-3$rd number of your student number.

The cost between node B and node D is $-4$th number of your student number.

The cost between node S and node B is $-5$th number of your student number.

The cost between node C and node D is $-6$th number of your student number.

The cost between node C and node E is $-7$th number of your student number.

The cost between node D and node E is $-8$th number of your student number.

The cost between node A and node D is $-9$th number of your student number.

If there is a $0$ in your student number change it to $1$ i$.$e if your student number is $215412807$ use it as $215412817.$ If there are repeating numbers like $218264666$ change it to $218264657$ or $218264678$ i$.$e add or subtract $1.$ Don$$t use a number more than twice. If you still have number repeated more than twice add$/$subtract $2$ or $3$ to the number to make it different.

$2.$ A class$-$C IP address is $195\mathrm{.}1\mathrm{.}1\mathrm{.}0$ is given, subnet it so that you have at least $2$ subnets of AB number of hosts, where A and B are maximum numbers in your student number in increasing order i$.$e if your student number is $21245689,$ then A$=8$ and B$=9.[20]$

$3.$ A class B network address of $131\mathrm{.}1\mathrm{.}0\mathrm{.}0$ is given and you need to create $4$ subnets with minimum hosts as $9$AB$,8$BC$,3$DE and $2$AD$.$

Where A$,$B$,$C$,$ D and E are taken from your student number as explained in table below. The student number taken here is $214001282.0$ and repeating number are valid for this question. $[40]$
