IT Infrastructure Project: Designing LAN Networks

IT Infrastructure Project: Designing LAN Networks 8

Here is my previous work I didn’t do so well! I did not have enough words in my Literature Review and I needed to add some other things, mainly design research

Professors Comments:

First, it is essential that future projects show a strong understanding of our frameworks from the assigned reading in the Cisco textbook. There should be a clear mapping of what we learned in our reading to the submitted Packet Tracer design. It starts with proper labeling and highlighting in Packet Tracer, showing the various layers, architectures, and framework implementations in your lab.

Please continue to work on a scalable and modular enterprise design. For example, the network edge is often where you spend some dollars to assure redundancy. At the switching layer, one switch failure only effects a select few users. This is not the case at the ISP level. Beyond this HA is essential along with the associated HA protocols and HA configurations.

I realize getting accustomed to the simulator takes time and I certainly recognize your efforts on this first phase of the project. However, your Packet Tracer design and configuration is less than 25% complete of where it needs to be for an organization with these needs and of this size. Your literature review is also short of the minimums from the standpoint of scholarly research, focus on design research, thoroughness/word count minimums, comparison/contrast of key research results on design, etc, etc. Thus, I gave a tremendous amount of grace on points this time but next phase needs to meet the requirements please.

I look forward to seeing improvement in the next project given we are gaining a stronger aptitude for the simulator the more we use it in the class. Start sound network architecture for an enterprise class network applicable to modern N-Tiers or beyond (e.g. cloud architectures). I have confidence that you will improve in phase two if you continue to work hard. Keep up the wonderful efforts and great job!

Introduction

The COVID-19 has tested the current infrastructure of all the hospitals in all the countries and most of the hospitals are looking for the advance solutions so that effective handling of this crisis condition can be possible. Like other hospitals, the "Friendly Careplease replace this with your name Hospital (FCH)" is also looking to improve its network infrastructure so that the currently faced issues with the used infrastructure can be minimized and human lives can be saved. The operational stability, accuracy and transparency in operations will also be archived with the improved networking solution at FCH. The increased count of patients and employees at FCH will require more network infrastructure so that the required tasks can be completed in minimum time. In newly proposed design to this Friendly Care Hospital RSA related issues, recovery related issues, security related issues and IP related issues will be handled easily. All the unwanted open entry points to the current networking infrastructure will be closed with this new design. The improvements in networking connections will also be performed so that departments of this Friendly Care Hospital can easily communicate with each other, and resource sharing can be possible among them. The unwanted costly devices like two firewalls will be minimized to one and security implementations will be improved with networking protocols and encryption. This is a good start! I have some suggestions as well. The introduction should be well supported. It should show a thorough literature review was performed and introduce key concepts from scholarly work. For example, what are the additional goals of the project and what can support the introductory design frameworks, strategies, and methods necessary to solve the design problems? Introduce these briefly. Please also introduce the framework and how this informs the design given the requirements and size of this network. Again, nice work thus far on your paper!

most of the organizations, Hospitals are responsible to provide their services 24*7, so, it becomes important that high RAS quality is maintained. Any failure of network infrastructure

component can cause issues to human lives, so, for recovery, separate implementation of servers along with backup facility will be carried out. The DHCP implementation will ensure the availability of this new infrastructure and NAT implementation will ensure the security requirements of this Friendly Care Hospital.

Recovery from disaster condition is very critical for the Hospitals as critical and confidential data of patients is stored in their servers. The implementation of backup server can help this friendly care hospital to handle the disaster condition. This hospital can take regular backup of all the collected data and can store that backup in the dedicated backup server.

Handing the confidential information of patients as well as doctors requires effective security in the network infrastructure of Friendly Care Hospital. Along with Firewall, there are different protocols like RSA, WAP2, encryption, ACL, security policies which can be implemented to remove the possible security breaches. Closing the unwanted network access points will also help in improving the security.

The IP allocation is most important for any new network design. As this is a Hospital, so, IPv4 implementation is recommended to the new design. The DHCP server can handle the IP requirements of all buildings. The following IP allocation is recommended to the buildings of this Friendly Care Hospital:

By implementing this IP plan with DHCP, the IP requirements of Friendly Care Hospital can be justified.

· Improved use of Ethernet and Serial connections.

· Removing IP wastage and using DHCP services.

· Implementing ACL, encryption, and other protocols to handle security.

· Maintaining backup server to handle disaster condition.

· Making global appearance with ISP connection.

· Closing unwanted entry points to the networking infrastructure

Development of logical design helps in effective implementation of physical infrastructure by identifying the issues in logical environment. Such required logical design developed for new

infrastructure related required of Friendly Care Hospital is:

Network Design

The framework topology made game plans for the medical clinic fuses end devices PCs and framework devices like switches and switches. The PCs are having inbuilt framework interface cards (NIC), which connects the ports with the multiport switches arranged at each floor of the structure. The switch hear is a 24-port switch which is used interface the PCs in star topology for LAN. The changes are used to interconnect all of the multilayer switches and web get to providers, each switch is having coordinating table and IP address which is used trade the data to the specific PCs. All of the affiliations completed with PCs and frameworks organization devices are related with Ethernet RJ45 joins. The workstations and remote enrolling contraptions are related with remote modems IEEE 802.11 rules.

As indicated by the logical investigation in this endeavor framework must be organized with the true objective that it should be versatile and reliable, it should be secure with data protected from outside aggressors. Before arranging the framework in the group tracer and repeating we need to incorporate sufficient isolation, flexibility, and versatility into the structure.

IP Configuration in all routers:

Conclusion

The networking related issues in hospital can cause issues to human lives and the existing infrastructure of this Friendly Care Hospital is full of issues. These issues are related to security implementations, connection development, backup plan, RAS, and placement of devices. The IP implementation related issues are also present in the existing infrastructure. Thus, the new network design is proposed to this Friendly Care Hospital, so, that, all these issues can be minimized, and operational stability can be obtained for this Friendly care Hospital. The effective use of IP, DHCP implementation and security protocol implementation along with wireless connections are defined for this Friendly Care Hospital. By using the provided recommendations, high quality of network infrastructure can be defined and maintained for this Hospital. Finish strong!
