Background Information for the Campus Network Design Project

 

XUMUC is a large online university in the Eastern United States. The university has an

 

enrollment of 90,000 students, mostly online. The students do not live on campus and are

 

scattered around the globe. XUMUC offers courses in the fields of arts and humanities,

 

business, social sciences, mathematics, computer science, the physical sciences, and

 

health sciences. Many of the professors are working professionals with jobs in the

 

business community, and only 5% of the 3,000 faculty have offices on the main campus.

 

Due to the opening of new online universities in the DC metropolitan area, the university

 

has had a difficult time attracting new students. The college wishes to attract and retain

 

more students, many of whom leave the state to attend more prestigious colleges.

 

Because of these reasons and others, the State advisory board expanded the Shady Grove

 

campus of XUMUC. Nine states colleges open their branches at Shady Grove location.

 

XUMUC?s management board now wishes to consolidate management functions at its

 

Shady Grove location.

 

The president of XUMUC formed an Advisory Group whose mission was to consolidate

 

IT functions and implement a state of the art network to attract prospective students. The

 

Advisory Group was also to determine why prospective students do not select XUMUC.

 

The group determined that many prospective students do not select XUMUC because

 

they perceive the computer facilities at XUMUC to be inadequate. In addition to the

 

computer applications used by the students and professors, the college administrative

 

personnel use the College Management System, which is a Novell NetWare client/server

 

application that keeps track of class registrations and student records. The Current Network at Shady Grove Campus:

 

The Shady Grove campus hosts 9 independent universities, working independently. The

 

campus has three main buildings and fiber optic cable is used for backbone connections.

 

The campus diagram is shown below. Each building is connected by fiber optic cable. Because most of the students that attend

 

XUMUC do so on a part-time basis, and because many of the faculty members have other

 

jobs, the assumption in the past has been that many of the students and professors use

 

computing resources at home or at work and do not depend on the XUMUC network.

 

The current network is shown in Figure -1.

 

Fig:-1 All the LANs at this site use 10-Mbps Ethernet although they can be upgraded to 100

 

Mbps. Every building is equipped with Category-5 cabling and wall plates in the various

 

offices, classrooms, and labs, though the cabling and wall-plates are not used in some of

 

the buildings. To support users in Building-3, multi-mode fiber-optic cabling was pulled

 

through cabling conduits to Building-1 and Building-2. At the Shady Grove campus,

 

XMUC uses the services of 4 ISPs for internet connections.

 

The college provides 10 Macintoshes and 25 PCs in the Computing Center (in Building1) for student use. A LAN switch in the Computing Center connects hubs, servers,

 

printers, and the router that connects to the Internet. Shady Grove campus does not have

 

its own web server. For security, packet filtering firewall is used on some routers. The

 

routers have default routes to the Internet and do not run routing protocols. Based on the

 

advice of the Community Advisory Group, the president started the ?Upgrade XUMUC

 

Project? with the goal of upgrading the computer and networking facilities. The three

 

network administrators and the Director of Operations for XUMUC formed the Project

 

Task Force.

Commercial Type in Copy Centre Voice Network:

 

Shady Grove campus has 200 telephones on a separate voice network. IP telephony is

 

used for internal purposes. PSTN (the Phone Company) is used to dial out. The logical

 

diagram is shown below. Security:

 

The site recently experienced an increase in network attacks (DoS). The network was

 

recently unavailable for a considerable time because of an attack. IT staff suspect that

 

these attacks are coming from a broad range of spoofed IP addresses, but are unable to

 

prevent these attacks. They have suggested installing a NID so that they can monitor the

 

network more closely and stop an attack while it is happening. Network availability is

 

crucial for the university because their revenue depends on availability of network.

 

Web server:

 

The director of the site wants to host a web site to increase revenue and share resources

 

among all the universities located at this location. His main concern is that a hacker can

 

access the internal network through a compromised web server.

 

RFP

 

The state government has funded this project on actual cost basis to upgrade XUMUC?s

 

computer labs and campus network. Even though the project is funded on actual cost

 

basis, the challenge with the network design is that the school?s budget does not call for

 

more money to be spent on network administration as needed, so the new design has to

 

be manageable and simple. The project task force issued the following RFP to upgrade

 

the network. Business and Technical Goals

 

The University Advisory Group identified the following business goals for the Project: Increase the enrollment from to 400 to 500 students by the year 2011 Reduce the attrition rate from 30 to 15 percent by the year 2011 Attract students who leave the state to attend colleges with more technological

 

advantages Provide more and bigger computer labs on campus Allow students to attach their notebook computers to the campus network to reach

 

campus and Internet services Reduce telephone costs Provide faster services Maintain (or reduce, if possible) the level of funding spent on network operations

 

The Project Task Force added the following technical goals: Centralize all services and servers to make the network easier to manage and

 

more cost-effective. (Distributed servers will be tolerated but not managed, and

 

traffic to and from these servers will not be accounted for when planning

 

capacity) Centralize the Internet connection and disallow distributed departmental Internet

 

connections Increase the bandwidth of the Internet connection to support new applications and

 

expanded use of current applications Standardize on TCP/IP protocols for the campus network. Macintoshes will be

 

tolerated but must use TCP/IP protocols or the Apple Talk Filling Protocol (AFP)

 

running on top of TCP Provide extra capacity at switches so users can attach their notebook PCs to the

 

network Install DHCP software to support notebook PCs Provide security to protect critical servers from intruders on the Internet and

 

internal network. Implement a technology to stop DoS attack Provide a network that can scale to support future expanded usage of multi-media

 

applications Use VPN technology to securely connect the Shady Grove site to the main

 

campus of XUMUC at Adelphi. Assume 2MB bandwidth available for data

 

network to connect to remote sites Provide a network that uses state-of-the art technologies Provide wireless network access to network users and guest users from any point

 

in the buildings. In conference rooms, users will get a minimum 284 kbps worth

 

of bandwidth. Other areas, such as the lobby or cafeteria, a minimum bandwidth

 

of 512 kbps bandwidth is required. (You can assume that a site survey is done

 

and no sources of interference or RF discovered.) Provide provisions for video conference and multicast services. The network administrators on the Project Task Force have been criticized in the past by

 

the students and professors, and are looking forward to proving that they can develop a

 

better network than the existing network. Getting support for this Project from the users

 

and professors is not easy, and the administrators now need to deliver a network that

 

performs well and has little downtime.

 

Network applications:

 

The XUMUC network is currently used for the following purposes: Writing papers and doing other homework, including printing the homework and

 

saving the work on file servers Sending and receiving e-mail Surfing the Web using Netscape or Microsoft?s Internet Explorer applications to

 

access information, participate in chat rooms, play games, and use other typical

 

Web services Accessing the library catalog Accessing WebTycho, where the online classes are located.

 

Students and professors in the School also use the following applications: Weather modeling. Meteorology students and professors are participating in a

 

project to model weather patterns in conjunction with other colleges and

 

universities in the state. Telescope monitoring. Astronomy students and professors have set up a PC to

 

continually download graphical images from a telescope located at the state

 

university.

 

Two new applications are planned: Graphics upload. The Art Department wishes to upload large graphics files to an

 

off-campus print shop that can print large scale images on a high speed laser

 

printer. The print shop prints artwork that is file transferred to the shop via the

 

Internet. Distance learning. The Computer Science department wishes to participate in a

 

pilot distance-learning project with the state university. The state university will

 

let WVCC students sign up to receive streaming video of a computer science

 

lecture course that is offered at the state university. The students can also

 

participate in a real-time ?chat room? while attending the class.

 

As a consultant to the school you are required to:

 

1. Propose a campus upgrade design that solves the current problems and meets

 

business and technical goals

 

2. Create a scalable network

 

3. Develop a campus upgrade design based on an Enterprise Campus module. This

 

module should compose of a Campus Core layer, a Building distribution layer,

 

and a Building access layer. 4. Provide redundancy at the campus core layer and the building distribution layer to

 

avoid failure at one point. For the Building Access layer provide a redundant

 

uplinks connection to the Building Distribution layer.

 

5. Select appropriate Cisco switch models for each part of your enterprise campus

 

model design from the Cisco Products Link, listed below, and use the following

 

assumptions in your selection process.

 

Selecting the Access layers switches:

 

a. Provide one port to each device

 

b. Make provision for 100% growth

 

Server farm switches: Assume 6 NIC cards in each server and one NIC card uses one port of

 

switch Dual processors and dual power supply

 

http://www.ciscowebtools.com/ProductAdvisor/child/1.0/switches.asp

 

6. Propose an IP addressing redesign that optimizes IP addressing and IP routing

 

(including the use of route summarization). Provide migration provision to IPv6

 

protocol in future.

 

7. Propose a security plan to secure key applications and servers. Note that

 

encryption of all application is not acceptable. Firewalls can be used as necessary.

 

Develop security policy to stop sniffing and man-in-the-middle attack. Your

 

security plan must be based on current industry standard Multilayer security or

 

defense-in-depth.

 

8. Integrate voice and data networking to reduce cost. Propose and develop a plan

 

for migration to voice network with in XUMUC sites as shown below. For dialing

 

out from XUMUC, propose a plan for 100% connectivity with the minimum

 

number of outside lines.

 

9. Create a wireless network for students, faculty, and staff. Building 2 and Building

 

3 have two conference rooms with seating capacity of 200 each and sized

 

approximately 40 feet by 60 feet. Building 3 has a cafeteria with an approximate

 

size of 60x60 square feet and a survey report indicated that at no time do more

 

than 20 guests use network services. Your task is to determine number of WLC

 

and AP placements, including how many of them to use and which model to use.

 

For your ready reference, the Cisco equipment guide is attached. In the Reference

 

Section, you will find a placement template and product ordering table for your

 

guidance in selecting equipment.
