The purpose of this reports is to make an efficient assessment of the existing network facilities of the particular organization and make suitable changes to the existing network dynamics of the company so that it can be easily incorporated with the business goals of the company and addressing the organization requirements of the company in addition to it.
The company that is being under consideration in this reports is a private biomedical development company. The company consists of two three story building software. In addition, this it is also being mentioned that the current network of the company is old and it is required to be replaced. Presently the company consists of 250 employees but most them do not require to use a computer hence the network structure of the company maintains a very basic network structure that comprises of only two dedicated computer rooms with a set of 10 computers and printers in each of the rooms. The network is connected by means of hubs and switches to the components and the peripherals. The network is connected by means of LAN in which the employees can log in by means of simple authentication techniques.
In the new network requirements for the company they want of provide a machine for all the programmers within the company would be provided an access point to the new network. In addition to this, there will be two computer rooms each with 20 computers one for Software Programmers and the other for Multimedia/Web Designers. There will also be 60 computers in the admin building. The two buildings for the company would be allocated for the two sets of employees; one for the technical workers and the other for the business and department. The network also needs to connect to the WAN at the branch office newly opened by the company. The company also needs video conferencing facilities within the network. In addition to this remote access to the network are also to be added within the network for the benefit of the company.
The report is used for the description of the network analysis and the implementation of an upgraded network according to the network specification stated by the company. The network requirements state by the company has been provided in the report and also main the main objectives of the network has been provided in this report. The report also provides the network requirements and the different type of hardware and circuit requirement for the network has also been provided in this report. The logical physical levels of the network have also been described efficiently in this report.
The requirements for the network has been provided in this part of the report. The network should be able to address both the technical and the business goals for the organization. business goals for the organizations are stated below:
In addition to this, the technical goals of the company provided for the designing of the network are:
The circuit of the network is done in both wiring structures and also in the wireless structures. The wiring within the network provides the provides the options to create access points within the network and also the wireless structures provides the remote access facilities to the network and also the security of the network is maintained separately in the wireless networks. The use of optical fibers would be very efficient for the network so that the VPN tunneling can be implemented efficiently in between the different network location and in between the different buildings of the network. the CAT 6 cables are used for the network that provide the network speed up to 100 mbps.
The layer 2 switches are used in this network as they have a total of 24 ports each. The layer 3 switches provide 48 ports for connection within the network but this, would result in the underutilization of the ports as there is not a lot of scope for all the ports in the switches to be useful. In addition to this, two severs and a number of routers are to be added in the network. one of these two severs would be a database server and the other would be the main sever that would have a control over the whole network. The Cisco Catalyst 2800 24 Port Layer 2 switch are used in the network as they provided very efficient 24 port and 8 port distribution for the network very efficiently. In addition to this, the Acer Altos R720 Rackmount Servers are used as the main server and the database server. The Cisco Catalyst 2800 Series Router and the Net gear WG302 Managed Wireless Access Point are also used in the network so the Connection within the network is properly distributed with the help of these routers. In addition to this, remote accessibility is also introduced within the network.
The Microsoft Server 2012 is installed in the main server of the network. The database servers are being configured with the Microsoft SQL Server 2016. The Microsoft Windows Server Enterprise 2012 is used for configuration within the whole network. The desktops of the users generally run on the windows operating systems and Microsoft Office 2016 are installed in the user machines so that official works of the users can be performed efficiently. Symantec End User Protection system is also installed within the system to protect the network from the possible threats that takes place within the network.
In addition to this the VM Ware Sphere operating systems are installed within the network so that the virtual network can be installed within the network. the VM Ware 2013 are used as these server are very useful and more efficient than the previous version of the virtual servers.
The old network of the company is primitive type is implemented with very less functionalities. The number systems that could be accommodated in the network was also very limited and hence the requirement of the new network design for the company arises. The old network was also unable to connect to the WAN services and it was also devoid of any type of remote access to it. The constructed network for the company consists of different layers. The physical layer describes the overview of the network. The network is to implemented within two adjacent buildings and each building consists of three floors each. The employees within the building should be connected to the network interconnecting the two buildings and they should be able to communicate within themselves provided sufficient access control system is implemented within the network so that the data within the network is protected appropriately.
Although the old network is almost neglected the new networks are to be created form the skeletons of the existing network. The network should also be cost efficient and provide sufficient security features for the company.
The network is divided in to two segments a wireless part and another part connect by means of the CAT 6 cables. The network also provides two types of accessibility to it. The LAN connection is limited within the buildings of the network and the network further extends to the WAN services and is connected remote servers that are connected by means of cloud technologies. In addition to this the virtual severs and the firewall are also installed in the network.
The design of the network has been done according to the requirements of the organization. The network has been provided with both instances of wired circuits and also wire free circuits. The CAT 6 cables are used in the network as they provide speed 100mbps which is very useful within the network. the VMWare VSphere is also used in the network so that the virtual servers can be implemented within the network. the optical fibers are used within the network so that the VPN tunneling within the network. The Microsoft Windows Server Enterprise 2012 are very useful implementation within the servers as they provide efficient access control and authorization within the network. The Netgear WG302 Managed Wireless Access Point provides efficient remote access to the users of the systems.
