I Require Only The Packet Tracer File For The Working Redesign List

I require only the Packet Tracer file for the working redesign listed below in the requirements IT INFRASTRUCTURE PROJECT PHASE I INSTRUCTIONS All labs must be submitted using the version of Packet Tracer in the online course/learning management system. Please do NOT use other versions of Packet Tracer to assure licensing compliance and proper assessment/credit. In addition, please do NOT add users or passwords to any device, leave all credentials blank for assessment purposes. Project Background Please reference Figure 1. Friendly Care Hospital is one of the biggest hospitals in DC. You have recently bought the hospital, naming it [Your Firstname Lastname] Hospital. For example, Jane Doe Hospital. Jane Doe Hospital owns a 5-story building and houses many departments that span multiple floors. Its Radiology department is spread across the first and second floors, connected by a dedicated local area network (LAN). The department has recently deployed a new “Radiology Images” application as part of their initiative to digitize patient records. However, the department staff sometimes faces long application delays during busy hours. It also experiences regular delays in Internet connectivity, FTPS services, web services, and email services. Their original design, depicted in Figure 1, was categorized as a small network, providing services for up to devices. They have well surpassed this. You, as their senior network administrator, are tasked with the job of a complete re-design. This design must support a medium to large sized network for over 1,000 devices. Thus, it should surpass the current capabilities. Figure 1. Current Friendly Care Hospital Network Design Project Overview In this project, you will study performance improvements in a congested, wired LAN/WAN environment that can be solved to varying degrees by a new IT infrastructure design and fully functional implementation in Packet Tracer. To learn more about Packet Tracer please read the Cisco Packet Tracer DS PDF. Later, in Phase II of the project, you will scale this design to a larger enterprise IT infrastructure. To begin the projects, you will complete a review of related literature to identify what is appropriate to improve system feasibility, RAS (reliability, availability, serviceability), security, and disaster recovery of the existing IT infrastructure and model of your hospital. Once this review of literature is complete, you will use the outcomes and research results to advance and improve the IT infrastructure. Proper data analysis, comparison, and contrast will be summarized within in-text tables and figures as well as appendices to explain the results of the IT infrastructure re-design and improvement. Packet Tracer is limited given it is a simulator. Be creative! For instance, if Packet Tracer does not have a file sharing service for a file sharing server, turn on any other related and relevant services that are available. As another example, use LAN and WAN protocols that are optimal given what the version of Packet Tracer allows. You will be assessed based upon optimal configurations in the version of Packet Tracer used. Thus, assure this is well studied. Research will outline new opportunities for future IT infrastructure designs, and this should be discussed accordingly in the written paper even if not configured in Packet Tracer. Often, new technologies are not implemented in industry immediately due to limitations such as hardware architecture. Please verify all requirements are met by reviewing the grading rubric. Below is an outline of minimum requirements with examples and ideas. Minimum Project Requirements • Submit a working Packet Tracer lab, typically this file has a .pkt file extension. o This will include the fully operational new IT infrastructure design o All devices in the lab must be named with your first name and last name – Example: Jane_Doe_Router_1 o All hardware and software should be configured properly and should be able to communicate using optimized networking designs, configurations, and protocols o No devices should have passwords for assessment purposes • Minimum IT Infrastructure Design and Packet Tracer Requirements o You must start with a blank/new Packet Tracer file, existing labs or modified labs of existing solutions will receive a zero without exception o Design a medium-size hospital IT infrastructure for well over 1,000 devices, and scalable beyond the Figure 1 example – For example, a design that goes beyond traditional N-Tier designs – Design proper addressing via IPv4 and/or IPv6 that scales – Add appropriate routers and switches to support this new design – Configure at least one appropriate networking protocol, operational across the entire infrastructure – Use proper network address translation (NAT) – Implement private and public IP address spaces correctly – Assure network traffic is organized, efficient, and secured properly (e.g., limit broadcast domains, do not allow marketing employees to access accounting systems, etc) o Add an Internet Service Provider (ISP) into the design o Add enough modularity, resiliency, and flexibility into the design o Design and implement the following new services and servers – A Dynamic Host Configuration Protocol (DHCP) server that automatically assigns working IP addresses to new workstations – A name server that manages the Domain Name System (DNS) for all servers in the hospital – A web server hosted on the Internet – Two new user workstations located at each level of the building that can use the new services properly • Show these services working on each workstation in your project (e.g., a website from the web server, DHCP, etc) Provide a few hospital departments as examples beyond radiology

Paper For Above instruction

The comprehensive redesign of the hospital’s IT infrastructure aims to elevate its network performance, security, scalability, and reliability beyond the constraints of the existing setup. This process involves transitioning from a small, outdated network to a robust, enterprise-scale architecture capable of supporting over 1,000 devices efficiently. The primary objective is to enhance the hospital’s digital services, particularly for bandwidth-intensive and latency-sensitive applications such as radiology imaging, patient record management, and communication services, ensuring seamless operations even during peak hours.

Fundamental to this redesign is the implementation of advanced network segmentation and hierarchical architecture, aligning with best practices for large-scale enterprise deployments. The new design adopts a multi-layered N-Tier architecture comprising core, distribution, and access layers, interconnected via high-capacity routers and switches. This structure isolates critical services and departments, reduces broadcast domains, and optimizes traffic flow. It further incorporates redundancy through redundant links and devices, ensuring high availability and minimal downtime in case of hardware failure.

Addressing scalability, the plan integrates both IPv4 and IPv6 protocols with scalable addressing schemes that can accommodate future growth. NAT configurations facilitate smooth transitioning between private internal networks and the external internet, ensuring secure and efficient communications. Segmentation of subnetworks assigns dedicated IP address spaces to departments, such as Radiology, Cardiology, ER, and Administration, enabling controlled access and security. Access controls and VLANs are used to restrict access, protecting sensitive information within different hospital departments.

Critical services like DHCP and DNS are central to the network's operational efficiency. A dedicated DHCP server automates IP address assignment, reducing manual configuration errors and simplifying device onboarding processes in all hospital departments. A centralized DNS server resolves internal hostnames and ensures reliable access to hospital resources, web servers, and cloud services. Additionally, a web server hosted on both internal and external networks provides hospital staff and authorized personnel with access to medical records, scheduling portals, and public information. Two new user workstations per level of the hospital are configured on each network segment, demonstrating the usability of services such as DHCP, DNS, and web access, including secure browsing and email services.

To enhance security, the network design incorporates proper segmentation, access control lists (ACLs), and secure configurations for all network devices. The use of VLSM (Variable Length Subnet Masking) ensures efficient IP address utilization, while NAT provides a secure boundary between internal and external networks. Additionally, implementing appropriate security protocols mitigates risks such as unauthorized access and eavesdropping. The design also considers disaster recovery by suggesting redundant power supplies, backup configurations, and plans for regular backups of critical network device configurations and data.

Further, the scalability and modularity of the network design ensures it can support future technologies and expansion. Modular switches and routers allow for easy upgrades and additions of new departments or services, while high-capacity fiber links support high throughput demands. The implementation of VLANs and inter-VLAN routing isolates traffic, streamlines network management, and enhances performance.

Each new service or device is carefully validated through simulated testing within Packet Tracer, verifying operational status and security. For example, DHCP servers assign addresses to new workstations, DNS resolves hospital-specific hostnames, and web servers deliver hospital resources to authorized devices. This validation ensures readiness for real-world deployment, facilitating a smooth transition from the existing network to a scalable, secure hospital-wide infrastructure. In conclusion, this comprehensive redesign advances the hospital's network toward a future-proof state, capable of supporting ongoing healthcare innovations, increased device density, and growing service demands.
