Delta Community College (DCC)-KEY Data:

All Routers are Cisco 2610 series and all Switches are Cisco 2960 series mostly running older version IOS. The 10 Mbps Ethernet is shared with each Classroom.

Dorm-1 and Dorm 2 are 10 storied buildings and house 400 students each.

Campus-A has 4 classrooms and houses only Arts and Humanities (500 students)

Campus-B has 12 classrooms, houses three Schools: Business (2000 students), Engineering (3000 students) and Social 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, 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-B. Each of these servers is a 2 GHz Intel with 4 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.

There are two dormitories for the students and each dorm can accommodate 400 students.

Distances from of different campuses are:

Campus B <—> Campus A = 10KM
Campus B <—> Campus C = 25KM
Campus B <—> Campus D = 15KM
Campus B <—> Dorm1 = 1KM
Campus B <—> Dorm2 = 1.5KM
Campus A <—> Campus C = 25KM
Campus A <—> Campus D = 12KM

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.

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:

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.
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.

Requirements, Issues, Constraints

Business Requirements:

As per directive from the senior team, all Campuses and Dorm 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.
Provide at least three WiFi Hot Points at each Campus to suit the building layout and the appropriate access for users grouped as “management & staff”, “students” and “guests”.
Plans to implement “Voice over IP” phone sets to the desktop, but the vender or technology has not being selected- you are free to recommend in your report.

Technical Requirements:

Apply a hierarchical approach to design this network. Your network design diagram should show:
1. Core Layer
2. Distribution Layer
3. Access Layer
Improve system Bandwidth for the users to accommodate for growth (assume 5% per year) at all Campuses.

Plan for Internet availability improvement

Required Public IP addresses for the College

Upgrade several of the server hardware platforms (to provide performance and fault tolerance) as seen necessary at any Campus(es).

Implement an Internet firewall (to provide security) wherever is deemed necessary.

Provide a more robust uninterruptible power supply (UPS) system (to provide fault tolerance and availability) for key infrastructure equipment and servers.

Provide secure remote login connections for 50 staff, who are mobile and work remotely from outside their offices. Make a suitable choice of technologies in this case. This number will double to over the next two years.

Technical Constraints:

Sub-divide and isolate the corporate network access from classrooms and the internet at Campus-C.

Business Cost Constraints:

A budget CDN $50,000 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:

Overall a Gigabit high availability/ high resilience architecture based on switched VLANS.
Technology for remote network management for monitoring servers, user PCs and access points that should improve service response time, and reduce costs. At present the IT department makes use of a help-desk ticket system to address such enquiries.

Ensure the security and integrity of data.

Provide statistics on the per-semester use of application software across the system.

Request for Proposal (RFP)

You are invited to submit proposals addressing these issues by preparing a Migration Plan over two academic years, within the allowed capital budget.

The deliverables and report format should include:

A project report in printed form and submitted in a folder – the report should follow the OACETT Technical Report Writing Guidelines (available on e-Centennial course folder). There is no limit on number of pages.

Course Title page should have:

Team Names

Project Assignment Title

Course Title

Fall 2016 / date

Grading Rubric: The distribution of marks will be as follows:

a- [4 marks] A full IP addressing scheme covering all classroom PCs and associated infrastructure devices, routers, switches, access points etc, at each Campus. Use a Class B private IPv4 address ranges and VLSM then as desired in your proposal.

b- [2 marks] Physical layer and network diagram of the network including cabling.

c- [6 marks] Design Document details of software and services (DHCP, DNS, Server OS etc)

d- [2 marks] separate Cost summaries in CDN $, ONE for each year

e- [2 marks] Clear project implementation plan of appropriate dates/times during the academic semesters when migration will be carried out.

f- [4 marks] Report style: A title page, a summary, conclusions and bibliography.

Due dates and submission process:

Project report will be due by Tuesday Dec 6, 2016.

An electronic copy of the same final report must be uploaded to the DROPBOX at e-Centennial course folder by 11:59 pm same day.

A group PRESENTATION will take place SAME DAY in class room, during the schedule Lab hours.

The 20% weight distribution of this project will be as follows:
1. 15% marks for the written PROJECT REPORT
2. 5% marks for the PRESENTATION
