Complete Computer Network Infrastructure for a Real or Ficticious Research Paper

Complete Computer Network Infrastructure for a Real or Ficticious Business - Research Paper Example After defining the specification, we will address network devices along with switch and router deployment. Moreover, we will define all the associated servers that will play a vital role in synchronizing data with remote offices in this scenario. Furthermore, a proposed network diagram will be represented for each site i.e. site 1 and site 2. Sub netting will play a dominant role in breaking down global IP addresses into local IP addresses for each node on the network. For the WAN architecture, we will discuss the technologies, protocols and services that will be used for connecting these sites together. Moreover, for maintaining and monitoring the network, we will discuss network security features that will be implemented in this proposed network. The RADIUS access server will provide synchronization of data between both sites operating on a Virtual Private Network. In addition, Domain name Service will also be discussed. 2 Introduction Organizations associated with health care need s to acquire up to date technological trends in delivering patient care at the optimal level. Medical information systems developed for supporting health care, facilitate organizations to align with best practices and quality and to make these health organizations successful in the market. However, acquiring and maintaining computer networks can be a difficult task along with its alignment with the goals and objectives of the organization. Moreover, along with the alignment with organizational objectives, involvement of all stakeholders in the implementation of a network is vital for understanding the purpose and benefits. Likewise, customization of network design is a requirement for supporting organizational goals and objectives, which can be a complex task. 3 Network Architecture 3.1 Topology We will apply star topology, as the network design will follow a centralized server / client architecture. Star topology will provide centralized administration and configuration of all the nodes on the network. Moreover, star topology initiates low broadcasts on the network, consequently, consuming low bandwidth and at the same time making the network capacity on optimal levels. 3.2 Workstations The minimum hardware specifications of the workstations that will be installed in the current scenario are: System Specification Processor Intel Dual Core E5400 2.7GHZ (2MB cache – 800MHZ FSB) Motherboard Intel DG41RQ (LGA775-SND+AGP+GIGA LAN-800MHZ FSB) Memory 1GB DDRII (800 Bus) Hard drive 320GB 3.5" SATA-II 7200RPM Optical drive DVD Drive 16 X Chassis Thermal HT Support 3.3 Network devices Network devices are the objects for any network. The network functionality relies on the network devices .The dependability of the network devices emphasizes on the requirements of the organization. For example, an organization dealing with 3D animation and rich media may require a Gigabit Ethernet rather than Fast Ethernet. This is because the subordinates share the animated data among themselves for various purposes. The 3D animation contents are large in volume and require gigabit Ethernet for moving files at a high speed within the network. Hospitals may share high quality medical images with remote offices, resulting in a consideration of bandwidth requirement of the Internet or site to site VPN as well. 3.4 Switch Implementation Fast Ethernet switches will be implemented instead of hubs. Switches are more powerful and intuitive as compared to hubs.
