Introduction
The Current Situation
Waterfront Tele-Support is a small company based in North Edinburgh that specialises in remote support for the clients of large Internet Service Providers.
The company inherited an old 10base2 network infrastructure which has reached the end of its useful life. Management have decided to remove the existing network and install a new network using up to date technology.
Below is the layout of the building:
101 Admin Staff102 Managers103 Board and Meeting Room104 IT and Technical Support105 Lockable room with Telecoms POP106 Staff Social Area107 Telephone Support Staff
The company’s staff are organised into 2 main departments: Tele-Support and Admin. The company currently employs 14 full-time staff as follows:
Managing Director: B Pasayet
IT and Network Support Manager J Dudek
Admin:Admin Manager J DoddAdmin Staff T McArdle
B ChangjiangB Hughes
Tele-Support:Tele-Support Manager K BarnesTele-Support Staff W Campbell
J McCabe

The company also employs between 2 and 6 temporary staff on a casual basis.
Factors influencing the project3.1 Functional requirement:
Requirement ID: Network Requirement: A network with new pcs and printers connected, the network should be capable of wireless network for laptops. A server will be installed capable of hosting the company website, remote services, and backing up the company systems. Depending on Finical status of the upgrade of the network, consideration of a backup server outside the company (incase of fire). Location: Waterfront Tele-SupportRationale: Without the equipment, the project would not be sustainable. Importance: CriticalRisks:
Pcs and printers may not be working. Networking hardware might be fail
Assumptions: Hardware will be new, equipment should be working.Pre- Conditions There is currently a 10base2 network in place.Post-Conditions The network should be installed and the networking should run smoothly with everything in place and connected.
Requirement ID: ServerRequirement: A server is to be installed, for hosting the company website, capable of remote management and backing up network and dns.Rationale: Without the server there will be no company website, remote management will not be possible and back ups of the network will not be made.Also give devices an ip address.Importance: CriticalRisks:
If the server is down the website will not be able to host the company website.
If the server is down then remote services will not be possible. If the server is down then backups of the network will to be possible.
Assumptions: The server will be working fine.
Pre- Conditions: There is not a specific detailed plan of the current network, detailing the hardware. So there is no way of knowing of a server currently installed. Post-Conditions: The server will be installed; the services that are installed (web server, remote services and back up services) will be installed and work efficiently.
Requirement ID: Network Security Requirement: The network must be secure from viruses hacking any threats to the network.Rationale: It’s a business, so there will be sensitive information that needs to be protected.Importance: CriticalRisks:
Security is most often breached due to human error, mistakes such as writing passwords down and leaving them where they can end up in wrong hands and unauthorized access could be granted.
Assumptions: The network is being built from the bottom- up, so Security will be set up properly Pre- Conditions. N/APost-Conditions: Network security will be set up correctly and the network will be secure from threats.
Requirement ID: Private StorageRequirement: Each team member/department is to have their own private storage.Rationale: Depending on the department depends on the size of the private storage allocated. It is as followed:
Importance: CriticalRisks: n/aAssumptions: n/aPre- Conditions. n/aPost-Conditions Depending on the departments the rules will be set for the storage to be set to the size stated above.
All Managers 25 GB eachIT Manager 100 GBAdmin Staff Shared 250 GBAll Staff private 5 GB each
Requirement ID: Web & Email Filtering Requirement: restrictions will be set on the Internet and email, websites and emails that are thought to dangerous and websites that are not work related.Rationale: Filtering websites, keep the network safe and workers focused on work.Importance: CriticalRisks: If there was no filtering the network would be vulnerable to attacks from bad websites and staff would be less encouraged to work as they could go on websites like Facebook. Assumptions: n/aPre- Conditions .n/aPost-Conditions Managers and directors will be able to manage the filers.
Requirement ID: Server backup Requirement: There will be a pc in the same room as the server making a back up for the server every morning at 2.30am Rationale: Having a pc making backup is a safety precaution for if the sever has a hardware failure.Importance: CriticalRisks: If a backup is not made then important data could be lost.Assumptions: n/aPre- Conditions .n/aPost-Conditions: A backup will be made every morning a 2.30 am when the server is least busy and will be stored on the spare pc.
Non- functions
Requirement ID: Budget Constraints Requirement: For the new network to be installed, there needs to be a source of money for the new requirement for the new network.Rationale: If there is no money then no new network can be built.Importance: CriticalRisks: n/aAssumptions: n/aPre- Conditions .the company has given a budget of £30,000Post-Conditions The network will be implemented within the means of given budget.
Requirement ID: Manual labor Requirement: A team will be in charge of all the manual labor, setting up the new network.Rationale: Without the team to set up the network, the project would not be able to be started.Importance: CriticalRisks: n/aAssumptions: n/aPre- Conditions team will be ready to set up the new network.Post-Conditions the team will complete all tasks given and the network will be fully functional.
Factors in detail
All staff must have their own networked pc’s, this includes temp staff that are hired, so there must be enough computers at hand for the maximum amount of staff both full time staff and hired temp staff.
The company will be looking to advertise the business; the IT manager has responsibility for maintaining a web Site, which is hosted locally and should be available for public access.
The Company network should be secured from virus, attacks form hackers, any external sources.
Any cabling should be installed in an unobtrusive manner and network connections should be positioned in convenient locations for connecting users to the network. All cabling infrastructure should comply with TIA/EIA-568B.1-2000 and TIA 569-A standards
The minimum requirement for initial network bandwidth implementation should be 100Mbps for any host computer or server on the network My design allows for future network expansion of at least 2x user numbers and 10x LAN throughput.
Costs for the whole network installation should be kept as low as possible while maintaining quality and standards. The total budget for the project should not exceed £30,000. Labour should be costed at a standard rate of £29 per hr.
All Staff should have Internet and email access, unsuitable web page content should be filtered. Other Internet traffic should be restricted for all staff except for the IT Manager and Managing Director who should have full Internet access.
A system should be set in place to back up data regularly. In the event of hardware failure the network should be able to be made fully operational as soon as possible and with no loss of data.
New desktop PC systems for all staff, and where necessary additional server computers and network devices, should be purchased and configured.
Each of the offices should be equipped with its own all-in-one laser printing device, except room 107 which should have 2 devices. The admin staff device should be able to print in colour, and should have access restricted to members of that department plus all managers. The Managing Director has a printer that is restricted to his own personal use. The printer for the managing director will have his printer plugged in locally to his own pc.
All Equipment must be new, Pcs Server, network media.
A muilti Business licence for windows 7 will be bought; so all pcs are covered with a legitimate. The server will have a single licence of its own.
Approach to the project
NETWORK
The network that is going to be put in place is going to be based using the extended start topology. An ISP will provide Internet for the company and the ISP will provide the company with the fiber optic connection and modem that will be connected to the firewall. Any Internet connection in or out will go through a netgear firewall the firewall will be one of the safety percussions that are apart of the new network. From the other end of firewall, two switches will be connected, from the switches the server, Pcs, Printers and a wireless Access point will be connected. Between the two switches there are 48 ports (24 per switch) this allows for future expansion if required.The Wireless access point that will be also connected to the switch and will lead through to the staff area, where staff can bring in their laptops and can log into their accounts through the domain wirelessly.Any media connected to the switches will be connected using Ethernet cable (cat5e) The modem, firewall, switches and server will be stored in a locked cupboard with a vent. The Ethernet cables connected to the switch will be sent through Plymouth through out the building and where pcs are needed they will be distributed through patch panels. Each room will have more patch panels available than currently needed; this leaves more connections to be added in the future and saves a lot of problems through out future expansion. The Server that will be connected will the deal with running services such as:
File Storage Web Server Remote management
Domain Services DHCP services Backup
The Pcs and printers that are connected to the switches are able to connected to the server and will all be connected to the domain that is created by the server.The server will also deal with hosting the company website through IIS. The server will be capable of remote services The Managing Director, IT Manager, all Managers, and admin staff so they can log into their accounts while being out of work using terminal at any time. Normal staff will be only be able to use this services between 7AM and 20:30PM and only locally from the company LAN.The Server also deals with each users personal storage(editing storage, this includes permissions for users and storing data users store in their personal drive). PCs connected to the switch will be given a static IP addresses. Laptops connected to the Domain through the wireless network will be given an IP Address from the DHCP server.Incase of a hardware failure with the server, the server will back up everything at 2.30am to another server with the same specs that will be ready to use, incase of the hardware failure to the original server.
Network Security
The network work must be safe from all threats, internal or external. Network Security Will is a big part of the network; a firewall will be in place between the outside Internet connection and the company network.
Web filtering – web filtering will be another Security feature, All staff will not have full access to the internet apart from the IT manager and the Managing Director, who have full access. This stops users going on dangerous websites and downloading things that could be thought to be a threat to the network.
Remote Access, The Managing Director, IT Manager, all Managers, and admin staff will have full remote access at all times to the network, no matter where they are. Normal staff will only be able to log in between 7am and 20:30pm.
Private Storage
Each User has his or her own personal storage, that only them and if needed the IT manager can access. They can store their important files and access them from anywhere when they log into their user account associated with their file storage located on the server.
Web filtering and email
Web filtering – web filtering will be another Security feature, All staff will not have full access to the internet apart from the IT manager and the Managing Director, who have full access. This stops users going on dangerous websites and downloading things that could be thought to be a threat to the network.
Staff Email - Staff will be given a personal windows live outlook email account Created, which has the companies email domain by the IT Manager. The IT manager has the overall power off the accounts, the IT manager can monitor, Change any settings, reset passwords, Any and the IT manager will be notified in the Outlook admin center.
Temporary staff will be given a template email account, for example there will be a maximum number of six temp staff hired at one time, so the admin will make six accounts:
1. [email protected] 2. [email protected] 3. [email protected] 4. [email protected] 5. [email protected] 6. [email protected]
Once a member off temporary staff has left, the account will be, reset to a blank inbox and the password reset to a new one so the old user has no access. Also when a full time worker leaves the company their email will be de-activated.
Server Backup
The server will take a full back up, then from the original full backup take differential back ups on a spare server that will be the same spec as the sever running and will be ready to go and run off the back ups made if a hardware failure occurs on the original server.
I have two options that I will have to look into further; I can use the Windows backup, or I can use acronious, I will look further into this during the implementation.
Permissions
There will be user permissions in place, pacific shared files, depending on whom the folder belongs to and who needs what access and what privileges they will have will vary. Wireless Access point
The wireless access point will be connected to one of the switches, and lead to through to the staff room, giving wireless connection to the network for laptops. I will buy a spare wireless access point just incase of failure of the first one installed.
The Server
The server will be running, the windows server 2008, the server hardware I have given more detail further on in the report. The Server that will be connected will the deal with running services such as:
File Storage Web Server Remote management Domain Services DHCP services Backup
The Pcs and printers that are connected to the switches are able to connected to the server and will all be connected to the domain that is created by the server.The server will also deal with hosting the company website through IIS. The server will be capable of remote services The Managing Director, IT Manager, all Managers, and admin staff so they can log into their accounts while being out of work using terminal at any time. Normal staff will be only be able to use this services between 7AM and 20:30PM and only locally from the company LAN.The Server also deals with each users personal storage(editing storage, this includes permissions for users and storing data users store in their personal drive). PCs connected to the switch will be given a static IP addresses. Laptops connected to the Domain through the wireless network will be given an IP Address from the DHCP server.Incase of a hardware failure with the server, the server will back up everything at 2.30am to another server with the same specs that will be ready to use, incase of the hardware failure to the original server.
Client and server licenses For the client Pcs multi volume licensees will be bought and for the server one server license will be bought.
Justification for design
The reason I have came up with this plan and I am so confident with my plan, is that first of all, if one PC or switch goes down, it wont effect the entire network, this is the reason I decided to go with the extended star topologies. Everything is replicable without the full disruption of the business. If the server goes down, there is another server with the current server back up to take its place. The server will be running windows server 2008 as it’s the most capable Operating system for running the servces required by the company with a single server license as only one will be used at a time. I believe that the security I have decided to use in the new network will ensure protection for the companies network. A firewall will protect the network from external threats. Web filters will protect the network internally as this stops users going on from dangerous websites. For the email, the company will use windows live outlook and create domains, windows live outlook store the users and new users on their own servers, but the company’s IT manager will have the rights to create, modify and monitor all email accounts.The overall physical design that I will go into more detail in stage two will cause no problems around the workspace. There are two switches so if one switch fails only half the network is down.Client PCs will be running windows 7 with a multi volume licensee. As previously mentioned for shared files, permissions will be in place to keep folders and files safe and secure. If the wireless access point stops working, then there will be a second one ready to install right away. I am very confidant in my plan.
I did look at different topologies like token rings, bus and other ones, however I noticed with some of the other topologies where quite unreliable, meaning if one pc failed, the entire network would fail. I also noticed for the equipment I am using best suits the topology I have chosen is best to use with my network media is the extended star topopgie.
I looked at different ways of backing up, I could create incremental back ups but this would take up both too much time and space on the spare server so I then decided to go with differential backups. I also looked at just storing back ups just on removable hard drives, however I felt, the server should be covered for all failures, so if anything goes wrong at all with the server, a exact double of the server is ready to go when and if failure occurs with the old back up ready on the spare server.
I compared server Operating Systems and Windows server 2008 was best compared to any comparators like Linux, All the clients are windows based, and for the services needed from the server like network storage, Remote services etc. Windows server 2008 was the best option.
For the email requirement, I felt it was easier to use windows live outlook, as it is one less strain for the network and the IT manager having to run the full email server their self. With the Outlook server the IT manager knows everything is safe as Microsoft insure this, well still being able to administrate, creating, modifying and monitoring email accounts under the company domain.
The Physical layout is the best way possible without there being any hazards. The network is very accessible with the plan that I have laid out.
For the licensing, there are going to be a lot of clients, so instead of buying a lot of single licensees, it is more cost efficient to buy a multi volume licensee of all pcs are covered.For the server, only one licensee is needed, as there is only one server active at any one time.
