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.

Paper For Above instruction

Designing a robust and scalable IT infrastructure for a healthcare facility such as a large hospital requires careful planning, comprehensive understanding of network architecture, and adherence to industry best practices. The goal is to upgrade the current network to support over 1,000 devices, improve system performance, ensure high availability, security, and disaster recovery, while maintaining compliance with healthcare regulations. This paper discusses the strategic approach to re-designing the hospital’s IT infrastructure, emphasizing literature-supported configuration, modernization, and security considerations.

Introduction

The primary objective of this project is to develop an advanced, scalable, and secure IT infrastructure for a major hospital that has outgrown its existing network. The design aims to address the challenges of long application delays, intermittent internet connectivity, and insufficient capacity by upgrading to a medium-to-large network capable of supporting more than 1,000 devices. This upgrade ensures hospital departments, including Radiology, can operate efficiently, providing timely patient care and data management. The project’s scope includes integrating modern network standards, expanding infrastructure, and incorporating resilient services such as DHCP, DNS, and web hosting to facilitate seamless operations across multiple floors and departments.

Literature Review

Effective hospital network design hinges on current best practices in IT infrastructure, including considerations for scalability, system reliability, security, and disaster mitigation (Kashap et al., 2018). Research indicates that modular network architectures and hierarchical designs improve manageability and scalability in large environments (Sharma & Kumar, 2020). The use of VLANs and subnetting optimizes traffic management, reduces broadcast domains, and enhances security (Li et al., 2019). The implementation of redundant core/aggregation layers with high-availability protocols such as HSRP or VRRP can minimize downtime, critical for healthcare settings where system availability is paramount (Anderson & Lee, 2020). Security frameworks emphasizing encryption, role-based access controls, and secure VPNs align with HIPAA compliance and protect sensitive patient data (Jones & Patel, 2019). Disaster recovery strategies incorporating cloud backups and redundant data centers are essential for maintaining resilience in the event of system failures or disasters (Zhang et al., 2021). Scholarly journals such as the Journal of Healthcare Engineering and IEEE Transactions on Network and Service Management provide insights into optimizing hospital network performance (Kashap et al., 2018; Sharma & Kumar, 2020). These standards and research findings form the foundation for implementing an efficient, reliable, and compliant IT infrastructure.

Proposed Network Design

The re-design of the hospital’s network adheres to a modular, scalable, and secure architecture. The core layer hosts high-capacity routers connected to multiple distribution and access layers, supporting over 1,000 devices across departments. The network incorporates hierarchical IP addressing with IPv4 and IPv6 support, segmented through VLANs to isolate departments such as Radiology, Cardiology, and Administration, thereby enhancing security and traffic management (Li et al., 2019). Dynamic routing protocols like OSPF or EIGRP are employed to optimize path selection and resilience within the network. NAT configurations enable secure internet access for internal devices while protecting the private network. The deployment of redundant switches and routers, along with protocols such as HSRP, ensures high availability. The infrastructure integrates DHCP servers for automatic IP assignment, DNS servers for efficient name resolution, and web servers hosted within DMZ zones to enable external access to hospital web portals securely (Jones & Patel, 2019). Firewalls and role-based access controls restrict sensitive information, adhering to compliance standards. The workspace devices in multiple floors are configured to utilize these services, with access controls to prevent unauthorized access to critical systems. Such a comprehensive design addresses the hospital’s needs for performance, security, resilience, and scalability.

Implementation and Configuration

Network devices, including routers and switches, are configured based on industry protocols and best practices. Routers are assigned hierarchical IP schemes, with interface configurations supporting IPv4 and IPv6. Routing protocols are fine-tuned for optimal convergence and redundancy. VLANs are created for different hospital departments, with inter-VLAN routing enabled via multilayer switches. NAT translations are carefully documented to allow secure external communication while protecting internal resources. DHCP pools are set up to assign IPs dynamically, and DNS servers are configured to resolve internal and external names efficiently. Web services are hosted on dedicated servers within a DMZ, with security policies restricting external access to only necessary ports. Security measures such as access control lists (ACLs), encryption protocols, and VPN tunnels are established to ensure data confidentiality and integrity. The configuration files from routers and switches are documented and included in appendices for review and replication. Regular testing and monitoring are implemented to verify connectivity, security, and performance metrics, ensuring the system operates effectively under real-world load conditions.

Discussion

The redesigned network offers significant improvements over the previous configuration. The hierarchical addressing and VLAN segmentation reduce broadcast traffic and improve security by isolating departments. Redundancy protocols like HSRP increase fault tolerance, minimizing downtime. The deployment of DHCP, DNS, and web services ensures dynamic, manageable, and accessible resources for hospital staff and patients. Moreover, security enhancements such as role-based access, encryption, and firewall policies align with HIPAA standards, safeguarding patient information. The scalability of the design accommodates future growth, including additional departments or technological innovations. The use of simulation via Packet Tracer provides a cost-effective way to validate configurations before physical deployment, although some limitations exist in emulating full-scale enterprise environments. Nevertheless, the simulation covers critical configuration scenarios, performance testing, and security implementations, offering insights into potential real-world challenges and resolutions.

Conclusion

The comprehensive re-design of the hospital’s IT infrastructure addresses existing limitations related to network capacity, speed, security, and resilience. By adopting a modular, hierarchical architecture with redundant pathways and secure services, the hospital can support over 1,000 devices efficiently and securely. Future considerations include integrating cloud-based backup solutions, advanced cybersecurity measures, and IoT device management to further enhance operational efficiency and patient safety. This project demonstrates the importance of aligning technological upgrades with industry standards and scholarly research to ensure a reliable, scalable, and secure hospital network infrastructure.
