AcknowledgementIt is of great and extreme gratitude and the help of various friends that I somehow achieved to complete this coursework on time. But most importantly I would like to express my sincere thanks of gratitude to our lecturer Miss Ama Kulathilake for giving us this golden opportunity to complete the NPS XE “NPS” coursework on time.
It has helped me in a lot of ways, I came to know about so many new things that I have never learnt before. My sincere thanks to Esoft for guiding us in every possible way, and most certainly a great privilege to learn under the guidance of Miss Ama. As a lecturer you are truly inspiring

Executive SummaryFrom this course known as Network Planning and Simulation, it provides us with an introduction that is related to this certain topic. It’s all about planning a network and the ways to describe a formal and optional flow of knowledge that can be considered as the basis for effective teamwork.

Understanding the method of Network simulation is basically an important tool in Network Planning. For this kind of method it is most important to have a good knowledge in understanding the network behavior. It is therefore crucial that the results of the simulation are sufficiently closed to reality.
The main importance of Network Planning and Simulation is modeling the behavior of a network by calculating the interaction between different network entities. Thus it contains various attributes of the environment that can be modified in a controlled manner and it shows us how to access the network under different conditions

COURSEWORK – NPS XE “NPS” – Part 1
Explain why the classful IP XE “IP” Addressing is not feasible to accomplish the task by using class B and C
Based on this scenario, the 8 class C networks technically gives you enough addresses to accommodate the 1800 hosts, but barely enough. Therefore there is a chance that the networks would need to be carved up quite a bit for example: likely needing to spread out multiple networks across a large area. As a result you would lose a certain amount of address space to overhead. Most probably nearly 90% could lead to depletion. Using a class B address would give us much more room for future growth and it would be much easier to partition
What is the most suitable technique to form a network with 1800 hosts?
The most suitable network technique to form a network with 1800 hosts is known as subnetting. It is a set of techniques that you can use to efficiently divide the address space of a unicast address prefix for allocation among the subnets of a network
What is / are the principle / principles of the technique mentioned in ii)
By subnetting the network, we can partition it to as many smaller networks as we need. This also helps reduce traffic and hides the complexity of the network.

All computers need the subnet mask field filled when configuring IP XE “IP”
You need to set some logical boundaries in your network
You should at least enter the default subnet mask for the class you’re using
How to determine the number of subnets and the number of hosts per subnet
Describe / display how to create the network with 1800 hosts using the technique mentioned in ii) and principles mentioned in iii
Network Address – 200.100.25.11/25
For 1800 hosts – (2^7= 128 – 2 = 126)
Therefore subnet mask is 25, Maximum Subnets – 128, Maximum IP XE “IP” addresses –126
New Network IP XE “IP” Range -200.100.25.0/25
Provide the following
The network ID XE “ID” of the new network with 1800 hosts – 200.100.25.0/25,
The subnet mask – 255.255.255.128,
The valid range of the new network – 200.100.25.1 – 200.100.25.126
The broadcasting ID XE “ID” of the new network – 200.100.25.127

Self-CriticismAs I start with the coursework known as NPS XE “NPS” , it comes to my mind that in some point that I am in the way of criticizing what I’m about to do. It is pretty tough learning new things.

We believe that being hard on ourselves could make us better people. If we fail at something that’s important to us, it can be very heart breaking. Such experiences can threaten the very core of who we think we are, and who we wish to be.

When doing coursework we have to cope with failure, so we often turn to self-protective strategies. They make us feel better about ourselves for the mean time, but they are less likely to improve or avoid repeating our mistakes in the future.

Therefore self-criticism has been shown to increase and impede goal progress. As a student you might feel worthless and incompetent
