Tech Institute/ IT Infrastructure- KEY Data:
The network, now outdated, has grown over the year in an unplanned way without much technical thought. Each Campus has separate agreement with an ISP for internet connectivity.
All Routers are Cisco 2500 series and all Switches are Cisco 2600 series mostly running older version IOS 11.x. The 10 Mbps Ethernet is shared with each Classroom via 3COM legacy HUBs – not shown in the diagram
Campus-A has 4 classrooms and houses only School of Media (500 students)
Campus-B has 12 classrooms, houses three Schools: Business (2000 students), Engineering (3000 students) and Health Sciences 1500 students)
Campus-C has 8 classrooms, and houses School of General Arts (350 students), and IT services (support staff of 20).
Campus-D has 4 classrooms and houses School of Aviation (100 students).
Overall the Institute has 7450 students- this number includes continue education students, 50 support staff, 50 instructors and about 20 Managers.
Each Classroom has 32 P4 1GHz PCs with 1 GB RAM and legacy NIC cards
The Server Farm consists of six servers which are located at Campus-C. Each of these servers is a 1 GHz Intel XEON with 1 GB RAM and a mix of legacy NICs
Campus-B and Campus-C are connected via a dedicated T1 link from a local ISP.
Campus-A, Campus-C and Campus-D have a contract with a local ISP for internet access.
All Campus User Groups who have been surveyed regularly, have constantly complained about the slow logins, slow downloads, and frustratingly slow response from the network services such as database enquiries, printing and internet surfing.
Campus User Group strongly lobbied that printing be made more user-friendly in all Campuses.
Users of the network were asked to complete an e-survey to evaluate the current performance of the network. A summary of the users’ feedback is shown here:
Summary of Traffic Analysis:
1- Generally at Campuses A, B, and D, the network is composed of a switched backbone architecture, in which traffic from all classrooms is fed into a central switch. At Campus-C, however, combined traffic from neighboring classrooms and staff office wings is fed into two central switches.
2- LAN Performance: The LAN Segment Utilization Table below presents the bandwidth utilization of the different segments of the network at Campus-C. However, this could be applied to all other locations.
LAN Performance
Requirements, Issues, Constraints
Business Requirements:
1- As per directive from the senior team, all Campuses would be WiFi friendly as well as all Campuses and their lab areas would be printer friendly- i.e. one can request printout from ANY station ANYWHERE and be able to get it from ANY printer ANYWHERE.
2- All users at each campus should have the option to access college network via WiFi Hot Points within the built up areas and the appropriate access for users which must be grouped as “management & staff”, “students” and “guests”.
3- Plans to implement “Voice over IP” phone sets to the desktop, but the vender or technology has not been selected- you are free to recommend any suitable vendor in your report.
Technical Requirements:
1- Redesign the whole network using the concepts of Core layer, distribution layer and Access layer as applied to Enterprise networks. Plan for system Bandwidth for the users to accommodate for future growth which is estimated at 20% per year at all Campuses.
3- Upgrade several of the server hardware platforms to provide performance and fault tolerance as seen necessary at all Campuses.
4- Implement an Internet firewall to provide security wherever is deemed necessary.
5- Provide a more robust uninterruptible power supply, UPS, system to safeguard against power failures for key infrastructure equipment and servers.
6- Provide secure remote login connections for 400 staff, who are mobile and work remotely from outside their offices. Make a suitable choice of technologies in this case.
7- Provide an estimate as to how many WiFi Access Points be needed at each campus to meet the item#2 under the business requirements. Submit for each of the campuses A, B, C and D, a logical design schema/diagram for WiFi Acess Points, and Wireless LAN Controllers.
Technical Constraints:
1. Sub-divide and isolate the corporate network access from classrooms and the internet at Campus-C.
Business Cost Constraints:
A budget CDN $ 25,000 per academic year has been approved for this migration.
Following could be treated as a wish-list from the IT support team- and only implemented if budget permits:
i. Overall a Gigabit high availability/ high resilience architecture based on switched VLANS.
ii. Recommend suitable software technology for managing all assets in such a way that should improve service response time and reduce costs as well as reduce current levels of human resource. At present the IT department makes use of a help-desk ticket system and thirty workers to address user enquiries.
iii. Ensure the security and integrity of data.
iv. Provide statistics on the per-semester use of software applications software across the system.
Request for Proposal (RFP)

Plan over two academic years, within the allowed capital budget.
