This report will show the operational requirement for the LAN at the University of Burton, this report will present a critical review for the backbone which will be implemented at the University of Burton the report will give very detailed critical analysis for the design and describing the main considerations that appeared for working on the backbone design. Finally this report will describe the communication medium, which has been used to connect the university's campuses, and why these types of communication mediums were chosen.
Introduction
This report will demonstrate how it intends to fulfill the requirements of the networking backbone as well as the structure required to maintain a high level of service and maintenance schedule required, to keep the UB's network system operational for periods exceeding 8000 hours. The report will also itemize in detail how it will deliver the requirements of the procurement of the LAN backbone for UB to have a network system that is capable of seeing the university into the next 5-7yrs.The report will show how it intends to meet all the regulations and provide warranties that are appropriate to needs and size of the installation.
Summary proposal
We are delighted to present this proposal for a network design in response to the Operational Requirements for Burton University. Our group has put together a design that has met all of the operational requirements for BU, and can be deliver the design network on time within the budget.
All buildings connected entirely with a Cisco router in each building and use a mesh topology. At the core of the network, the system that is designed is most reliable, high speedand fiber optic with built in future proofbackbone. The design accommodates future upgrades and expansion; also have most reliable Internet connection with a security firewall
Description of System Proposal
In this part we will explain about the proposed system, we will start with the core network diagram that shows the logical and physical connections.
The University of Burton consists of two sites. The main site of BU consist the main site of BU is made up of 6 Buildings A, C, and D has six floors each. Buildings B, E and F have three floors each. The second site of BU consists of two buildings, G and H, both have six floors.
Each floor is connected to two Cisco catalyst express 520 switches, one switch for labs and the other switch for staff, all labs switch that connected to the main lab switch and also all staff switch that connected to the main staff switch, and the main lab and staff switch must be connected to the Cisco unified communication 500 series router.
Both labs and staff main router that are connected to the outside building Cisco ASR 1013 router, this routers connected to the main server switch to the firewall that is connected to outside world at the wired core. The Cisco catalyst express 520 switch fastened seven servers which are supposed to be allocated at IT room and Full video conference system POLYCOM QDX6000 are provided in buildings B and G with a Sony 42 inches FULL HD TV.
The backbone for the network will be used fiber optic pair cables outside the buildings; to secure communications with high data rate and wide bandwidth and on the other hand to ensure the fast running of the backbone. Fiber optic cables have advantages that long distance transmission with light weight and easy to upgrade in future, so it has also disadvantages which that more expensive than copper.
Category 7 cable will be used inside the building to allow 10 Gigabit Ethernet over 100 m of copper cabling and connect the network to individual outlets in all buildings, and also is used to link the network backbone to distribution switches on each floor. The advantages of Cat7 are that it has a lower cost and also secure transmission shielding keeps signal within the cable. Cat7 has disadvantages that if both ends of the cable are connected ground may have earth loops problems (revise sentence).
We use two ISPs because we have believe that the advantages of a link balancer appliance and in the event one ISP fail; the public IP addresses could still be routed via the other ISP. Within each building we used Cat7 Ethernet cable to connect the BU backbone to distribution switches on each floor.
The reason that we chose T5(OC12) for our final choice because its really very fast speed 622Mbps but in same time its very expensive. T3 speed 45Mbps is a backup line that we need for network availability
The system we designed is most reliable, high speed 100Gbps and fiber optic backbone, and spare fiber cables will be laid alongside so that we can be connected instantly if an existing cable fails, to reduce the downtime.

Network Backbone
Servers (seven units):
http://www.safad.com/Website/Portals/0/ProLiant%20ML350%20G5.jpg
We allocate the servers at the IT support office of the BU, the servers that we will implement are mail, proxy, Data, Web, Print, DHCP/DNS and RADIOS server.
(Remote Authentication Dial In User Services) RADIOS server provides centralized management of the network, authentication protocol utilized by IEEE 802.1x security standard.
DNS/DHCP provides services add DHCP distributed hosts automatically to DNS Server. And also the DNS server can convert the web addresses into IP address. The DNS/DHCP Support Relay Agent, PXEBOOT, BOOTP, Zone Transfer, DHCP Range Filters.
Data is a server which provides FTP for local machines ,database storage system,
Web is a server that can store pages from site, ordered by user via Web site browsers and web server is capable to manage to host the website depending on the bandwidth that is provided from the ISP.
Proxy is servers that can acts as a cache to increase the speed of loading web pages and the server arranges the requests from clients to other servers.
Mail is a server that can create e-mails on the web and that handles sending and receiving messages (as internal or external). It has the firewall within it, that gives a high level of security
Printer a server can manage to control the requests for printing files that connect printers and clients.
These servers are HP ProLiant ML350 G5, is the most flexible tower servers in the worldwide which is designed with a high performance, consistency, and expandability features. The server that supports VOIP, and Each one of the server is linked by two Layer 2 and switches:
Cisco Catalyst Express 520 Series

It manage to provide the customer very high security and performance, which serves the all
requirements for the business applications. It has very efficient cost and intelligent network
switches, which are made mainly to be appropriate for mediums businesses and also has feature to deploy and employ.
Cisco unified communication 500 series:
http://newsroom.cisco.com/images/2007/presskits/products/ps2007/ps2007_prod_02.jpg
Cisco Unified Communication 500 Series is vital for security and management advantages, which has many features such as speed and VOIP support. It's easy to manage and communicate, all that make it absolutely helpful for small businesses.
Cisco ASR 1013 series:
Product Small Photo
We use Cisco ASR 1013 Router embedded firewall because it supports applications and services
with 360 Gbps total system bandwith and it has 4 to 23-mpps packet forwarding abilities. And
Also it support services and applications like voice gateway, (DPI) deep packet inspection, and
firewall and IP security (IPsec). The reason we chose Cisco ASR 1013 router is the most
powerful edge device and it embedded firewall and it capable to increase the strength the network
edge to support Internet video, emerging Web 2.0 applications, but in other hand it has
disadvantages which that more expensive device.
Video Conferencing:
Full video conference solution - which is pre-made by companies such as Cisco, Polycom, the solutions which was recommended by some of our engineers was to search for quality system and best pricing, so we found the video conferencing kit from Polycom and the HD TV screen from Sony. The main features in our system very secure and great quality system

To be connecting the 20 site we need 20 miles of fiber optic with spare cables that make 40 miles means 64.37 km = 64370 meters and also on the top of that we need 700 meter for each building that make 700 * 8 = 5600 meters that will make in total 128740 of fiber optics.
We should include the prices of the internet service for T5 the University of Burton needs to pay 10,000 £ a month and also for T3 the University of Burton needs to pay 1000 £ a month.
Conclusion
The above report demonstrates that BU can have a future proof system that is up-to date and scalable, to tackle into account any future expansion requirements that the University may need and an infrastructure capable of managing high traffic load and resilient and secure.
