Abstract

In this report, the planning to design the network will be discussed and demonstrated in detail. The planning to design the network layout will be made according to the scenario given in the requirements. The plan will be implemented by the evaluation of the aspects that are important to design the network and other necessary things to design and implement the network. After implementing the network, the network will be tested by secure communication, WAN communication Channel, Wireless network, and PAN network. The troubleshooting of the network will also be discussed and elaborated in detail. The protocols used in this network will also be taken into consideration. 

Introduction

           Designing a network is not a simple task for someone. There are different phases to design the network. Each phase has a very important role to design the network. The first phase is to collect all the requirements to design the network. The second phase is to evaluate the requirements to make sure that either requirement is enough to design the network or not. After evaluating the requirements, the third phase is to implement all the aspects that are gathered in requirements. The fourth and last phase after implementing the network design is to optimize the network by performance. 

Network Layout

The physical arrangement of the network is called network layout. The network layout of the given is scenario is shown below:

Diagram created using CISCO PACKET TRACER 7.3.0

Demonstration

This network consists of two different places one place is headquarter which is the main point of this network and another place is Therall which is the working point of this network. 

Headquarter

In headquarter, the Executive office, R&D, Reception, Guest office, and accounting office’s host are connected with one switch. Twisted pair cable is used in this part of the network. Each device directly connected with the headquarter switch. 8P8C (Actually, RJ-45 is the more common term) jack is used in this part of the network and it is located in the reception area. Bus topology is used in this part of the network. (I think that what you have in your diagram is a bus-star hybrid. The switch is the bus, the individual cables to the hosts are the star)

Thrall

In Thrall Remote, the Engineering area, production area, and reception area’s host are connected with the switch. Twisted pair cable is used in this part of the network. Each device directly connected with the headquarter switch. 8P8C jack is used in this part of the network and it is located in the reception area. Bus topology is used in this part of the network.

For both 1 and 2: type of cable, where do you map the runs and place the jacks (I gave you a building layout), and what is in the telecom room, e.g., server, patch panel, demarc, router, etc? 7 points each.

Secure Communication

Communication through this network is secure because it is a private network and has less vulnerability. An unauthorized person cannot reach this network. The transmission control protocol is used in this network 

Sarju, this is not secure from building to building (server to server, or really, network to network) or from an employee home to the server (host to network). A man in the middle attack with a packet sniffer would eat your lunch. You are still thinking like a computer person and not like a network person. While what you say is true, it really doesn’t secure a network. The only way to really do what I asked is with a VPN using PPP and either PPtP or L2TP as the security wrapper. 5 points.

T3 WAN channel helps to transmit data over the network is a secure and reliable way. The transmission of data in this channel is fast and accurate. The bandwidth of this network is 1000 Mbps. For long-distance, TCP/IP protocol is used. 

What is a T3 WAN provide for bandwidth and speed? How is it formed and terminated. In other words, what is a T3 and how does it work. And, it is not secure.

Wireless network

The wireless network is set up by radio signal frequency. It used this frequency to connect two different devices. It is very easy to set up and configure in the network. It is fast and easy to understand and establish.  Sarju, this was supposed to be about the wireless networks? Devices, placement, bandwidth, discussion of 802.11, etc. I think you missed something here.

PAN

PAN stands for Personal area network. PAN is used in personal devices and is normally connected with the higher-level network it is normally used to provide communication between devices like computers, mobile, and laptop. The range of the PAN network is very small. The range is10 meters. Its frequency for Bluetooth is between 2.4 GHz to 2.48 GHz. 

You didn’t really explain your network…just told me what a PAN is. I would have liked you to discuss ICS with DCS and maybe PLCs. A quick bite of SCADA would be good, too.

Troubleshooting

It is a very complex task to troubleshoot the network because sometimes the fault is a miner and does not found easily. In the given scenario, the network will be troubleshot by check the wired connection and by checking the router configuration. 

Where would you start? Probably at the demarcs and work in. If that was okay, you should call the ISP. Need more detail. 4 points.

OSI model

OSI stands for open system interconnection. There are seven layers in the OSI model. Each layer is used for a specific task. The 7 layers of OSI are described below:

· Application layer

· Presentation layer

· Session layer

· Transport layer

· Network layer

· Datalink layer

· Physical layer

What about the TCP/IP Model and encapsulation /De-encapsulation? What is that all about? And what about using the example of a web page to explain the process? 2 points.

Overall, a lot more detail is needed…31/100

Conclusion

In this report, the planning to design the network layout according to the given scenario is discussed and demonstrated in detail. Different phases to design the network are also discussed in detail. Some optimization of the network by testing the network are also discussed. We also implement the project plan to design this network. We also studied and implement the different cases on this network.
