Hardware Devices For Network Setup And Design

Desktop and Monitor

Project hardware requirements

The following section of the project indicated the hardware devices that will be required so that they can be used after the network has been developed. The idea behind this is that we need this because we realise we are building a  network design from scratch and therefore this has made us to also come with new devices so that they can be fixed in admin, classes, labs and the libraries respectively. requirements comes with the minimal specifications the devices should have.

Network Design

In network designing we must consider the network requirements that are based to the economy as the demands are always set by what the institution get [3].  The idea behind this choosing of a diagram will also be based on the security that is needed to be achieved at the end of it all. This designing of the network selection has really helped in adjusting the changes in loading off traffic that help to maintain the consistence of the response time of all connected applications [4]. There are some several guidelines that must be achieved so that we come up with a good design that help in meeting all the needs and the requirements of the institution.

1. Goals and the technical requirements of the institution must be verified
2. The features and functions that need to be met must be determined
3. Readiness of the network assessment must be performed.
4. Site plan must be created in advance
5. Lastly is creation of a plan of the overall.

The guidelines goes hand in hand for any computer that is connected over the network and need to be completed and hence they meet the user needs [5]. The are four major requirements that need to be approached for any design selection as stated below.

1. Scalability
2. Availability of the network
3. Security.
4. Manageability

In this network design with reference to what has been put by the institution is that we need to select a hierarchical network design which has three layers as explained below. The diagram will be explaining the three layers and showing some illustrations and on how they can be configured and installed.

Core Layer- this is the connections of distributed devices in the distributed layer

Distribution layer- used for connecting devices in networks in smaller networks like that of the classroom

Access Layer- this provides the connectivity for the network hosts and to that of the end-user devices.The Logical diagram.

In this concept we have the simulation of the expected hierarchical network diagram that will be used in designing the physical design of the network. The simulation indicates a router which is configured as follows so that it can communicates with switches and the internet service providers.

Server

The justification for this figure is that it shows that there are four labs and four class rooms and al of them seems to be communicating very nicely. If I want to send a message from Lab 4 to classroom 1 then I can try as shown below and if the result is successful then the diagram is justified in showing the network is communicating in the different rooms.Network Device and Configurations The network mask and the IP addresses.

The case of scalability in this network will be a major step in knowing the mask of the network and the class of the Ip addresses to use [6].  In this case we will use the Class B of the IP address which will supports the scalability as well as the how flexible it will be. With about more than 130 hosts then the institution will need a range that would effectively allow future extensions and much more which are appropriate. The table highlighted below explain the range of the details of the institution that could be applied.

IP ADDRESS	IP Class	Network Address	Subnet Mask	Subnet Bits	Host Bits	Number of Subnets	Host per subnet
172.40.0.0	B	173.40.0.0	255.255.248.	19	13	32	2046
	The Ip Addressing of the Institution
Floor	The Subnet	Subnet Mask	Subnet Size	Host Range	Broadcast
1	172.40.0.0	255.255.248.0	2046	172.40.8.1-172.40.7.254	172.40.25.25
2	172.40.8.0	255.255.248.0	2046	172.40.8.1-172.40.15.254	172.40.15.255

Router configuration

A router is a device that is used for connecting the devices in the two floors occupied by the institution.  The router is used also for provision of access to connections externally like the internet where we have the case of cloud-design approach. The screenshot below explain how the route is configure with a switch.

 

Figure 4 Shows the routers and switches before they are configured

The figure below shows the button being red showing that the router and the switches cannot communicate not unless we configure the routers. The router will be configured following the command instructions as explained here below so that the router can communicate efficiently with the router such that the buttons on cables to indicate color green which indicates that the data packets can be transferred from one device to the other.

We click on the router and select the CLI tab and start inputting commands.

— System Configuration Dialog —

Would you like to enter the initial configuration dialog? [yes/no]: no

Press RETURN to get started!

Router>enable

Router#config t

Enter configuration commands, one per line. End with CNTL/Z.

Router(config)#interface fastethernet0/0

Router(config-if)#ip address 174.40.0.0 255.255.255.0

Bad mask /24 for address 174.40.0.0

Router(config-if)#interface fastethernet0/0

Router(config-if)#ip address 192.168.10.1 255.255.255.0

Router(config-if)#no shutdown

Router(config-if)#

%LINK-5-CHANGED: Interface FastEthernet0/0, changed state to up

%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/0, changed state to up

IPhone

Router(config-if)#exit

Router(config)#int fa0/1

Router(config-if)#ip address 192.168.11.1 255.255.255.0

Router(config-if)#no shutdown

Router (config-if) #

%LINK-5-CHANGED: Interface FastEthernet0/1, changed state to up

%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/1, changed state to up

Router#%SYS-5-CONFIG_I: Configured from console by console

After you type the no shut down command and click enter then the router should change its state to that of the configured one and the buttons of the cabling will need to change to green showing clearly that they are communicating with the switch an much data packets can be transmitted from one device to the other. The figure or screenshot the configured root working.

 The router configuration with the Computers.

The following steps are followed when we are configuring the PCs so that they can communicate with the devices as shown below. In this case we have three devices that are connected to each other and for them to communicate the router first of all. Just like with the case with the above router switch configuration we open the router CLI and use the following commands as explained here below as they will help in accessing the layers one on one, help in assigning the ip addresses to the available interfaces, changing the interfaces status and that is from down to up, assigning the ip addresses to the PCs and lastly is assigning the default gateway to the PCs connected as explained and shown

Press RETURN to get started!

Router>enable

Router#conf t

Enter configuration commands, one per line. End with CNTL/Z.

Router(config)#int fa0/0

Router(config-if)#ip address 192.168.1.1 255.255.255.0

Router(config-if)#no shutdown

Router(config-if)#

%LINK-5-CHANGED: Interface FastEthernet0/0, changed state to up

%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/0, changed state to up

Router(config-if)#exit

Router(config)#int fa 0/1

Router(config-if)#ip address 192.168.2.1 255.255.255.0

Router(config-if)#no shutdown

Router(config-if)#

%LINK-5-CHANGED: Interface FastEthernet0/1, changed state to up

%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/1, changed state to up

After you type the no shutdown command and click enter the state of the devices will change from down to up showing that they are communicating.

 As shown above in figure 7 its shows now that we can be able to access the interfaces one by one because we have already assigned the IP addresses. This will be justified by the change of lights from color red to green.

The next step so that we make the PCs communicate with each other over the network will be to assign the IP addresses to the PCS and this can be explained as shown in the dfollowing steps.

Switch

Click on the PC0 and select the desktop option and click the Ip config tab.Following the same procedure like in PC0 do the same for PC1 and assign the IP address as explained in the Screenshot below.Figure 9 PC1 IP address assigning

Now when we are done with the assigning of the IP address on the PCs then we realize that the communication now is enabled as now the two PCs can now communicate via the routers. To justify that we need to click on the packet and then click PC0 and then Click PC1. If the status shows that the packet are communicating by giving us a successful result then we have done all what is needed and our logical diagram is communicating as it was expected.

Demonstration of the Physical network Devices

There are many devices that has been used in making this network suitable and convenient so that the institution can be able to communicate effectively at all times and much more meeting their objectives. The following will be a small illustration explaining how the network devices functions and how they work together in sharing the network resources.

1. Switch is a hardware device that is used for connecting devices over this network and works within a single LAN [1]. There are various types switches which depends on the network size and how scalable it may be like. The figure below illustrates some of the commonly used switches as available in the packet tracers and in real senses.

1. Routers

This are devices that are used for connecting the network with the web. They are used for offering provisions of all devices that are embedded on any accelerating encryptions, DSP slots being expanded, firewalls, preventions of the intrusions, processing calls etc. A router has a lot of capabilities than many other capabilities. A router is able to analyze the data that is being sent on the network, changing the package and send it any other network may it be to a different network [7].Figure 12 Router Connection

1. Server and the storage components

Servers are components used for managing the access of all resources that are shared within the network. The servers that are mostly used like in this institution will be like the mail-server, file-server, Domain Name server, Dynamic Host Configuration Protocol Server.Many are servers that are assigned one task and they are referred to as dedicated server since they are required to deliver services that are always required constantly as they are not turned off(They run 24/7) [8]

1. Workstation Devices

These are devices that are connected to the network which may include things like the desktops, printers, scanners, IP Phones.

1. Ethernet cables

This are the cable cat 6 which are used for the provision of connections between the devices on the access layer in the organization network.

1. Wireless Access Points (WAP)

This is a transceiver kind of a device that is used for creation of a wireless LAN which is the Wireless Local Area Network (WLAN). This device is mostly known for broadcasting the WI-FI signals within an organization and this will eventually allow the users for connecting to the Local Area network.

1. RJ 45 port and Connector

This is a cable with a connector that is inserted on the RJ 45 port so that the workstation device can connect with other devices over the network. It also help the devices in accessing the internet.

Conclusion

In the above discussed design of the institution network much will be needed especially to come from the institution like the budgeting and much more allowing room for the above to be analysed and implemented in all ways. We have discussed on the benefit of using the hierarchical network design as it will be easy when we need to expand may be in future and hence no need for us in designing another structure of the design. The logical diagram does not cover all devices but it only covers a few depending on the way we will demonstrate and then from there we will draw the exact design after we identify the physical topology. If all what has been discussed will be followed keenly then we will have an easy time when designing the network for the institution and much more less time and effort will be used.
