IT Networking Design & Proposal for MonkeyNet Canberra Hospital-CIT

This report presents an IT networking design proposal for MonkeyNet Canberra Hospital, focusing on upgrading the current network infrastructure to connect different floors and improve network security. The proposal addresses the need to reduce network load, enhance security, and efficiently allocate bandwidth for remote clinics. It identifies drawbacks in the current infrastructure and provides solutions to minimize network downtime and increase efficiency, including the implementation of wireless routers with different subnets. The design includes logical and physical network diagrams, aligning with the hospital's business requirements and goals. Cost analysis, project scheduling, and resource allocation are considered for budget planning and project advancement. A layered approach with VLANs and access control lists is used to segment the network and secure access, aiming to meet business requirements, improve network performance, and ensure scalability while staying within budget. The design incorporates fault tolerance and server security measures, utilizing an IP subnet plan and firewalls to enhance overall network security and manageability. The document is contributed by a student and available on Desklib.

IT NETWORKING DESIGNING
Executive Summary
The report is prepared for MonkeyNet Canberra Hospital for the up gradation of the current
network infrastructure and connect with the different floors of the building. The main
requirement of the organization is to reduce the load on the current network and improve the
security of the network framework. The remote clinic connected with the network and efficient
bandwidth is allocated for reducing congestion in the network channel. The drawback of the
current network infrastructure is found and a solution is created for reducing the network
downtime and increasing the efficiency of the solution. Wireless routers are also installed with
different subnet for increasing the flexibility of the network. Logical and physical network
diagram is created for the development of the network solution. The requirement of the customer
is analyzed for the development of the network design and aligning the business process for the
deployment of the networking device in the organization. The cost of the devices and calculated
by creating a project schedule and assigning resources for the development of the network
infrastructure. The cost of the project should be calculated for preparation of a budget plan and a
proper planning is made for the advancement of the project. The network design is created
according to the project plan and the network design is created into two different parts such as
logical design and physical design for segmenting the network and making the requirement clear.
A network development model is selected for the development of the network infrastructure and
flexibility and scalability of the network is considered for the development of the network. A
layer 3 switch is used for the network and different VLAN are created for the different
departments for reducing congestion in the network. The routers are configured with access
control list for denying access of the unauthorized users and securing the network. The main aim
of the network administrator is to reduce the network downtime and develop the network
infrastructure within the estimated project budget. The project implementation plan is created

and project scope is developed for allowing the network to expand according to the growth of the
organization. The network should be able to tolerate fault and the servers installed in the network
should be installed in a separate zone for blocking the physical access of the servers. The
network design meets all the business requirement and goals of the organization for increasing
the efficiency of the network. An IP subnet plan is created for the development of a high level
security design and proper routing and switching protocol is used for communicating with the
remote clinics connected with the network. For increasing the security of the network solution
firewall is used and the unwanted traffic are blocked. A class B IP address is used and proper
subnet is used for the allowing the host to be connected in the network. Internal NAT is used and
wireless access point is installed in different location of the campus for allowing the authorized
users to connect their wireless device with the organizational network.

Key business security requirement
The main requirement for designing the network is to improve the security if the network
and the risk associated with the development of the network should be eliminated for increasing
the efficiency of the network solution. The unauthorized users should not be able to access the
devices installed in the core part of the network. The routers and servers should be installed in
the DMZ zone for restriction of the physical access of the device sand eliminate the risk of data
loss.
Security design for the remote clinics
A security design is created for connecting the remote clinic with the organizational
network and demonstrated below.

Design and routing and switching protocols
For the development of the network design the application of proper network routing and
switching protocol is important. The router should be configured with proper IP addressing
scheme following the addressing plan. The interface of the router should be assigned with the IP
address and the subnet for connecting with the network device installed in the network (Zhang et
al. 2014). The routers should be configured with IP routing protocol for communicating with the
different departments and it should also be configured with ACL for blocking the unauthorized
users from accessing the core components.
The switch should be configured with spanning tree and VLAN for allocating different IP
address for each of the VLAN created. Each of the buildings are assigned with different VLAN
and layer 3 switch is used for the connection of the different departments (Horst and Miller
2013). The device used in the network should be password protected such that unauthorized user
does not have access of the device for intruding into the organizational network.
