Jane Doe Global Hospital owns a network of hospitals supported by four (4) office buildings.Their original design, depicted in Figure 1, was categorized as a medium-size network for 200 to1,000 devices. They have well surpassed this and added new services in telemedicine. Inaddition, it has several flaws. You, as their senior network engineer, are tasked with the job of acomplete re-design. This design must support a large-size network for over 1,000 devices,address the current design flaws per figure 1, and meet the future needs of a globally capablehospital IT infrastructure. *Note, each of the office buildings in Figure 1 also contains additionalrouters, switches, workstations, and servers that would support a typical hospital office buildingof this hospital size. Include these devices to meet the rubric requirements as you design thedetailed version of this network. Regardless, only one workstation is needed per network switchto show working functionality.Project OverviewIn this project, you will study performance improvements in a congested, wired WANenvironment that can be solved to varying degrees by a new IT infrastructure design and fullyfunctional implementation in Cisco Packet Tracer.Project Requirements Take screenshots demonstrating your network, servers, configurations, and protocolsproperly functioning in the new design. Screenshots must include a unique piece ofinformation identifying the student’s computer along with a proper operating systemdate/time. Submit these as appendices in the Word document. Submit a working Packet Tracer lab, typically this file has a .pkt file extension.o This will include the fully operational new IT infrastructure designo All devices in the lab must be named with your first name and last name Example: Jane_Doe_Router_1o All hardware and software should be configured properly and should be ableto communicate securely using optimized networking designs, configurations,and protocols Packet Tracer IT Infrastructure Re-Design Requirementso You must start with a blank/new Packet Tracer file, existing labs or modifiedlabs of existing solutions will receive a zero without exceptiono Include the existing hospital network design but optimized/improved LANs must function using the OSPF protocol Buildings 1 and 3 must connect to buildings 2 and 4 using a properlyselected and configured WAN protocolo Design a large-size network for over 1,000+ devices An appropriate WAN design supported by research is necessary Add appropriate routers and switches to support this new design Design and configure at least one appropriate networking protocol,IPv4 or IPv6 Design IP addressing that will scale to over 1,000 devices Use proper network address translation (NAT)o Add appropriate security into the design, at least one (1) significantimprovementPage 3 of 4o Add sufficient modularity, resiliency, and flexibility into the design, at leastone significant improvement for each for a total of three (3) optimizationso Design and implement the following new services and systems Assure each service supports telemedicine A Healthcare Enterprise Resource Planning (ERP) system Requires four front-end web servers Requires load balancers that balance traffic to the front-endweb servers Requires two database servers Requires a storage area network (SAN) to store all data A website hosted on a web server in each ISP, accessible by allworkstations Two new user workstations in each building that uses the new servicesand services properly Show these services working on each workstation in yourproject (e.g. the Healthcare ERP, the websites in the ISPs) Paper Requirements (Introduction, Literature Review, and Conclusion)o Submit a properly formatted APA paper in Microsoft Wordo Here is an example paper:https://owl.english.purdue.edu/owl/resource/560/18...o Table of Contents that automatically adjusts page numbers of the mainheadingso Introduction Introduce the primary goals and objectives of the projecto Review of literature that supports the new system simulation, model, anddesign Include appropriate IT frameworks and standards in which to design alarge enterprise class IT infrastructure and network Address system feasibility, RAS (reliability, availability,serviceability), security, and disaster recovery Include at least 10 scholarly journal articles focusing on relevantresearch on the problems being addressedo Packet Tracer design explanation Explain each of the additions and improvements Reference the primary configurations and how these were developed Include running configurations from routers/switches as appendiceso Conclusion Highlight any limitations, managerial implications, and conclusions ofthe project deliverables and outcomes
