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.




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




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


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




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.
