1Network Redesign for FNUOverview Business Domain:The network redesigning is required at The First National University (FNU). FNU is a highereducational organization for long distance learning. This is the first educational organizationproviding online courses in the country. The university runs online training and courses; it requires anetwork infrastructure of very high performance to provide Quality of Services to the end users. Theuniversity covers 5 regional campuses and 10 metropolitan campuses and a main campus to runsuch a huge educational institute. University offers undergraduates programs and postgraduateprograms through distance learning. Moreover it provides Vocational and Educational Training (VET)as well as short programs for professionals to increase their skills. FNU teaches 45,000 students atboth undergraduate and postgraduate level for various programs on-campus whereas 15,000students are studying off-campus for distance education at FNU. To ensure services to be deliveredat all the ends, FNU’s network is designed to divide into 3 facility centers. Firstly, Headquarters,where main campus is located. Second, Operation i.e. Data Centre which is located 50 km away fromheadquarters. At the Operations center, the technical staff is appointed for managing andperforming IT related tasks required for proper functioning of the network. The third division is theBackup Facility. Backup facility is located 1000 km away from the main campus. This is becausebackup facility is needed only when operation facility breaks down. Network Issues:1.As discussed above, due to heavy number of users on the network, it may result in network slowdown. The online submission is the key facility provided by FNU for ease of submission andevaluation for the students as well as staff members. Due to online submission for both on-campusand off-campus students, it has been observed quite a few times that the network problemsappear which makes the late submission for most of the students which in turn results in the badgrades. 2.FNU has no Bring your own device (BYOD) and Work at home (WAT) policies embodied in thenetwork which is highly needed by the students and staff to make it possible to work from theirown devices. For this purpose, the secure wireless network should be implemented whichsupports BYOD and WAT.Immediate actions to take in regards of the identified issues:1.Scalability for 50% increased enrollment in next three years.2.Improvements with issues in online assignment submissions.3.Implementation of bring your own device policy by adhering wireless network in the campus. This enables the students to work on their own laptops, tablets, notebooks and smartphones. 4.With WAT it will allow users (students and staff members) to access network facilities from
2their homes. 5.Security measures must be taken to safeguard data from the hackers.6.Providing Quality of Services to the network users both at on-campus and off-campus.Identify Organisation’s Needs and ConstraintsBusiness GoalsFNU is divided into regional and metropolitan campuses that are all similar in size of infrastructure,staff members and technology. These campuses are all well built with network and requiredtechnologies which serves at its best to the students studying in that campus. With academicteaching and learning activities both on-campus and off-campus, FNU also has 12 external partnerssome of them are:Hospital: FNU deals with providing training to students for hospitals. On the other fair side, FNUhelps hospitals to get their best interns at the optimum search. The hospitals get benefited byappointing best candidates at their hospitals with limited searching. The university offers all themedical related courses which help hospitals to get the best suited candidate.Research Center: FNU may help students by providing current research practices due to itspartnerships with research centers. It benefits students for future reference. On the contrary, theresearch centers uses data and statistics from the university to research further about a particularfield of interest. FNU ties up with such research centers to allow them to perform researches insome areas.Vendor Support and Technology are other fields FNU have partnerships with which one or theother way benefits the students learning process. Also, the FNU offers campus interviews for thestudents to get placed in various companies which in turn benefit the companies for selecting bestcandidates on the basis of their grades.As per the requirements discussed above for FNU, it becomes very important to identify theorganizations goals to provide best services to the users of the network, be it students, teaching staff ortechnical staff. The business goals are as elaborated below:1.The university is currently having 45,000 students at both undergraduate and postgraduate levelfor various programs on-campus whereas 15,000 students are studying off-campus for distanceeducation. Future goal of university is to expect new enrollments of 50% rise in upcoming threeyears. From the business point of view, the FNU is preparing to add new students both on-campus and off-campus. FNU presumes to increase the students at the largest possible rate byproviding learning in new and currently trending fields.2.The FNU provides day learning courses for on-campus students. These activities can also beextended to short training programs to attract more students and get more enrollments on-campus. Some short training courses should also be undertaken with certification that willattract more students seeking for on-campus education for limited time period.3.The off-campus online courses provided by the university are limited to some extents. Toincrease the enrollments, it is required to introduce new training courses. With new courses
3added in online training or long distance learning it is possible to attract off-campus students fordistance education. 4.As far as partnership related expansion is concerned, the FNU administrative and managerialstaff must communicate with more hospitals, companies and research centers. These partnersextension result in attracting more students. Also it may result in recognition from various otheruniversities. 5.To provide large number of courses for huge number of students, FNU is aiming to provide thebest network for the users. The current goal is to redesign the university network to provide endto end services without any interruption. Many students using network all the time must have aheavy load at every moment. FNU aims to use better network policies for the entire network.6.Foremost goal of FNU is to increase students and this increase in students will result in heavyloads at metropolitan campuses. This will result in increased number of regional campuses fordistributing students.7.University also aims at providing BYOD and WAT policies in the network for more usability in thenetwork.Needs of improvements in FNU Network:1.Since several numbers of students and staff members uses the network, FNU network must bevery good at providing best performance. Right from internet surfing to downloading files,sending emails and providing high end network performance is the high need of the network.2.The business goal of FNU is to increase number of students by 50% in the next three years;hence it requires a network design which is highly scalable in nature. New PCs at campus mustbe added up in the network without much overhead is the basic need of the network since morenumber of students is expected to be increasing in upcoming years.3.The university provides off-campus distance learning and hence must be available at any timefor its distance learners. Moreover, it requires the student’s on-campus to submit theirassignments online; hence availability of network is very important at that part as well.4.FNU must also provide Bring Your Own Device and Work AT Home policies in the network formore usability in the network. These policies are highly needed at the university since it isaffecting the usability of the network. Once more and more personal devices can be connectedto the network, it will affect in overall students learning process.5.FNU needs to implement a secure wireless network which safeguards student’s logincredentials, files, and other important assets. Moreover, it may restrict the intruder getting intothe network by facilitating strict security measures. Authentication will also need once BYODand WAT policies discussed above are implemented in the network to filter illegal activities. Theother security measures should also be taken to protect important files in the server.Constraints in FNU network1.Foremost limitation of FNU network is that it does not support bring-your-own-device (BYOD)which makes it difficult for students to migrate their work from university PCs to laptops andvice versa. With this limitation students cannot work from their own laptops, notebooks ortablets.
42.The network does not support work at home (WAT) policy which does not allow users to accessuniversity network from their personal spaces. WAT must be provided by the university whichwill help staff members to carry their pending work out from their homes.3.Another noticeable limitation is that it sometimes fails to upload assignments due to poorperformance which leads in late submission of homework. This eventually results in poor gradesof the students. The load at the deadline of the submission is observed to be very heavy in thenetwork which results in slow down of the network and hence students are unable to uploadtheir assignments on time.4.The main campus of the university holds large number of users including students and staff.Other campuses like regional and metropolitan campuses are in similar sizes and technologyusage. All those campuses use old complex technologies which are out-dated and results inpoor performance of the network. Some technical issues are also noticed in the network which is needed to be noticed and fixed as early aspossible. The technical goals related to the university network as discussed below:Technical Goals:1.Scalability Scalability can be best defined as the ability of the network to ensure no degradation in overallnetwork performance even if the network size in increased. Scalability is one of the mostimportant features a sound network can attain. It is the property of the network to add devicesto its existing cluster in such a manner that new added devices do not collectively form a loadthat exceeds the cluster’s collective load to offer adequate performance. Scalability onceattained on the network, provides good quality of services in the network since it eventuallyrelates to the network performance.The redesigned FNU network must have this feature so that it can be scaled to supportextended usage of services including multimedia applications. This feature is important in FNUso as to include online teaching in its training part. FNU must provide scalable network forfurther enrollments of the new students both on-campus and off-campus. This features must beemployed everywhere at all the campuses. There are several techniques to attain scalabilitythese are, Network Load Balancing (NLB), scaling up and scaling out. Network load balancing isthe trustworthy technique that allows the network to assess the load on the network andbalance it to provide better network performance. FNU network needs high scalability for itsgoal to enroll 50% of the current strength in next three years. 2. Availability (half a page)The organizations with multiple data centers, network availability are a vital concern. Toperform operations daily such as downloading files from server at FNU requires high needof network availability because users performing daily operations in the network need thenetwork to be available all the time. Availability is serious when it comes to disaster
