Objective
The assignment has been designed to enable you develop:
  • Understanding about routing algorithms



Note: Material that is an exact copy from handouts or internet would be graded zero marks. Your solution should consist of the material found through different sources and written in your own wordings.


Assignment Statement:
Give detailed comparison of all routing algorithms with respect to the type of network.

assignment solution

Question:
Give detailed comparison of all routing algorithms with respect to the type of
network.
Solution:
Routing algorithms can be defined as a mechanism that tells the router how to
process. All these algorithms are different from others regarding their design and
efficiency and type. Routing algorithms can broadly be divided into following
categories;

 
Ø Static versus dynamic
Ø Single-path versus multipath
Ø Flat versus hierarchical
Ø Host-intelligent versus router-intelligent
Ø Interadomain versus interdomain
Ø Link-state versus distance vector
 

All these algorithms have different design, different working and different
metrics to measure the best paths for routing.


Static versus dynamic 

Static algorithms are actually the tables that are created by the network
administrator before the beginning of routing; they will not be updated till an
administrator does it manually. While the dynamic routing algorithms are updated
as they find any sort of change in routing paths.

 
Single-path versus multipath
The single path routing algorithms have a single path to the destination while
multipath algorithms allow traffic to route over multiple lines in order to get more
efficiency and load balancing.


Flat versus hierarchical 

The scenarios where flat algorithm routing protocols are implemented, the
routers are just like peers to each other while in hierarchical algorithms routers
might be differentiated into backbone and non-backbone routers and so is their
functionalities.

 
Host-intelligent versus router-intelligent
Host intelligent algorithms let the source routers work involuntarily and
mindlessly, they just send packets and leave the decision on destination routers.
In router intelligent algorithm routers define their path to destination regarding
their own routing path calculations.

 
Interadomain versus interdomain
Routing algorithms that are restricted to only work within the domain are referred
as interadomain routing algorithms and if they are not restricted only within the
domains then they are interdomain algorithms.


Link-state versus distance vector
Link state algorithms, all routers send the states updating of their linked nodes to
all other nodes in the Internetwork while distance vector algorithms are able to
send only the major changes to its neighbours.

Problem Statement: Calculating No. of A Grades in Class

You are required to write a program which should take input from user in the form of characters A or B. Based upon user’s input you should calculate no. of A grades. You should use while loop or do/while loop for taking input and if / else condition for making decisions.




Detailed Description:

The program should display like;

Please Enter Grade (‘A’ OR ‘B’ )

Then the program should take 10 inputs one by one,

  • After taking 10 inputs, you should display no. of A grades.
  • If A grades are less than or equal to 2, you should display a message “Your class is Poor!”.
  • If A grades are less than or equal to 7, you should display a message “Your class is Good!”.
  • If A grades are greater than or equal to 8, you should display a message “Your class is Brilliant!”.
  • The user should enter either A or B. If user has entered other than A or B, e.g. C,D,E etc. Your program should display a message like; 
     "Please Enter 'A' or 'B' grade only!"

Sample Input and Output

Please Enter Grade of student 1 :
A
Please Enter Grade of student 2 :
A
Please Enter Grade of student 3 :
B
Please Enter Grade of student 4 :
A
Please Enter Grade of student 5 :
B
Please Enter Grade of student 6 :
B
Please Enter Grade of student 7 :
A
Please Enter Grade of student 8 :
B
Please Enter Grade of student 9 :
C

Please Enter ‘A’ or ‘B’ grade only!
Please Enter Grade of student 9 :
A

Please Enter Grade of student 10 :
A


   
Total No. of A Grades = 6

Your Class is Good!



Deadline:
Your Assignment solution must be uploaded/submitted on or before November 05, 2010
