Network Design (part B)
PART B 1 (a) Business goal for the given scenarioThe NTN nursing school has its main campus located in Sydney. The major business goalof institute is to operate in different locations so that students from various sections can accessthe school. For the same purpose NTN has two additional satellite campuses as well. To enhancenumber of students enrolled in school and to provide more practical exposure to the candidatesNTN also aims at establishing its collaboration with private hospitals. This collaboration will notonly allow its students to work under expertise authorities but will also increase brand value ofnursing school. The long term business goal of institute is to establish effective networking channelbetween its students, private hospitals and patients so that its home care vehicles can provideservices to greater extent. At present they are operating in nearby localities only but in futureNTN has goal to provide services at a wider scale. These objectives will help institute to givemore practical knowledge to the students and to accomplish their mission of delivering healthcare services. The NTN also aims to double number of its students by next year. For achievingthis goal, it is required for the nursing school to establish superior position among otherinstitutes. These goals can be achieved by implementing proper networking between main andsatellite campuses of NTN as well as with its collaboration with the private hospitals. It willrequire efficient networking in mobile home care vehicles. 1 (b) Constraints affecting business goals of NTN nursing school The institute has to deal with several constraints which can act as barrier to achieve itsbusiness goals. The following constraints need to be addressed at priority to enhance goalachievement process. NTN must establish effective networking between its satellite and main campus. Thelectures are provided by virtual classrooms thus entire working of satellite campuses iscompletely dependent on technology. The technical failure due to weather relatedconditions, external disturbances and system errors can completely abolish working(Chang, 2016). It can directly affect the brand value of school among visitors andstudents.
The virtual classrooms are restricted with size of classrooms. Sydney campus cannotsupport more than 200 students at the same time. During instances of medical emergency,it may require coordinating with faculties but technology limitation may not supportrequirement (Berendsohn and Geoffroy, 2016). This can create an adverse impression inthe minds of private hospitals and they may not provide efficient support to nursingschool considering its technologically backward. The home care vehicles at present do not have facility to exchange photographs andreports. It can enhance the possibilities of error. Such errors in health care services arenot advisable and thus can lead to performance related errors for students as well as forthe NTN school. The private hospitals have Wi-Fi access points for communication. The higher networktraffic and less security measurements can make it difficult for these hospitals to interactwith nursing students of NTN who are involved in telemedicine and home care vehicles.Thus, these hospitals can consider the institute as inappropriate for integration. It willaffect the long term goal of NTN to provide practical exposure to its students. 1 (c) Technical goals of NTNThe technical proficiency in networking is essential for nursing school to achieve itsbusiness goals. For smooth functioning of the activities NTN must achieve following technicalgoals: The institute must implement secure data stores which can accomplish effective datamanagement with secured features. The foremost technical goal for college is to ensurethat security level of its networking is maintained and data is protected from unauthorisedaccess. With the integration of private hospitals NTN may require information processing fasterin case of dealing with medical emergency. Thus, its communication system must beeffective in managing network traffic and quality of services. The data transfer speedmust be maintained and high enough so that networking errors do not affect operationalactivities (Sahingoz, 2014).
Another technical goal of nursing school is to meet increasing demands of future byenhancing and updating network capabilities. Network must be designed in a way thatgrowing number of users does not degrade quality, security, affordability and speed ofnetwork rather it maintains its integrity and quality. 1 (d) Trade-offs in achieving technical goals NTN may experience the following trade-offs in achieving its technical goals. The strict standards of performance such as redundancy, data accuracy and integrity aswell as security characteristic can make it difficult to achieve affordability technical goal.In order to meet future demands scalability must be in alignment with security and costaspects. The availability of resources is also another considerable factor. NTN must have clear guidelines regarding trade-offs between authorised accessing andtransparent and quick management functions. The trade-offs between security and cost is challenging. With rapid advancements it canbe hard for the nursing school to make a balance between it. The number of users alsoaffect this balancing. The increasing number of users also affects risk factors and network compliances(Seppänen and Kloetzer, 2015). To ensure minimum vulnerabilities of cyber andnetworking threats access permissions must be reviewed and controlled. 2. (a) User communities The required network design will have following user communities. Students of NTN nursing school: The students can require network services for attending virtualclasses and to interact with their lecturers and corresponding authorities of private hospitals. Staff members of private hospitals: The collaborated Private hospitals may require coordinatingsenior authorities of nursing school and participants of mobile health vehicles. They may alsorequire networking services to share the details of patients.Management of all campuses of the institute: NTN has its satellite campuses which may requireinteraction for managerial decisions and activities. For resolving sensitive issues, they mayrequire more secure and broad networking space.
