Business Goals and Constraints

Network design denotes to the planning put in place to implement a computing network infrastructure. It involves the evaluation and having the understanding of the scope of the network to be deployed. The entire network is presented as a network diagram that acts as the blueprint for the implementation of the physical network. Main activities in a network implementation include but are not limited to cabling structure, IP addressing structure, logical diagram of the network to be put in place, network security facilities and location, quantity and type of network devices (Pop, 2012).

In this document we are designing network for NTN College. Basically, our task will be to implement the above mentioned list of activities.

List of Business Goals and Constraints

A business goal denotes to objectives that a company prospects to achieve and a business constraint refers limitations such as time, physical, fiscal limitations that are anticipated as parameters that are affects the business goal achievement. NTN private nursing experiences the following list of business goals and constraints:

Goals

1. Improve NTN’s business communications to real-time and be instant based.
2. Modernize NTN’s outdated technologies

• Improve partnership with intern students

1. Readily avail data to employees within offices of NTN and home-care employees to make best decisions.
2. Improve computing security especially patient data.

Constraints

1. Staffing and budgetary: budget and staffing is another hot topic in a profit making firm. Most of the administration will want to have huge marginal outputs in relation to inputs. This is, of course why they are in the market, is it so? Us as networking we may right and materials to implement the network design. For instance, implementation of homecare unit will require most recent technology to be implemented (IoT), we understand that the newer the technology the more expensive it becomes. Telemedicine implementation will require resources. Additionally, as project will be in progress more staff will be needed. The two above will be a constraint to our client NTN.
2. Scheduling: implementation of this project may time due to logistical processes to be adhered to. For example, acquisition of licenses from the government may be a hurdle, hence affecting the scheduling of the entire project.

• Policies and politics: our client NTN is likely to encounter politics staffs and us the network designers. However, professionally, as network designers, we will listen to the politics and perform what is expected.

Technical goals

1. Scalability: scalability denotes to how much growth our network design will support. In part of NTN’s management requirements, we are informed the network is expected to double. This must be included in the network design. Additionally, scalability also entails how many applications, WAN links, users and new technology will be accommodated without performing a redesign of the network.
2. Availability: NTN’s network should be 99.9999% availed due to homecare facility which will be used to diagnose patients remotely.

• Reliability: reliability is a factor of accuracy, reduced error rates and more stability. NTN network should error free and more stable as lives of patients will depend on this accuracy.

1. Performance: performance measures response time in terms of throughput, accuracy, utilization, efficiency latency and time between request time and response from the receiver. NTN’s network is expected to be highly performing since some goals such class virtualization will require real-time kind of operation.
2. Security: our network design is expected to protect both inside and outside resources against network threats.
3. Usability: this technical goal defines how easy NTN’s employees access network services and resources will. For instance, users will require to access share files in order to work on them(Nogueira & Salvador, 2013).

Trade-offs

There are a set of trade-offs which are made to ensure that the technical goals will be attained. In the meantime the trade-off is a process that advocates the lessening or the leaving aside of some of the looked-for good results of that the project would have appreciated for the expense of another decent result. Our NTN has to trade-off more positive returns in order to upturn more staff to work as teachers to the predictable number of students.

Table of User Communities, Data Stores, Network Applications and Traffic Flows

 A user community denotes to the group of people who are legible to use our NTN nursing school network infrastructure. Below is our user community table

Model for addressing and naming

An IP address refers a unique number that is assigned to a networked computing device to uniquely identify it on the network. In our NTN network design, we are going to use Class C IP address type. Our service provider given IP is assumed to be 192.168.10.0 /24. We are using VLSM subnetting to allow future growth. Our model for addressing are tabulated below.

Naming

Naming is key in a networked environment as it helps identify a network device by name. Our naming structure will follow the following naming structure.

Location_DeviceNameNo for instance, switch 2 in Darwin satellite campus will be, Darwin_Switch2.

Explanation and justification of the logical network design

The diagram below shows the logical diagram network design for NTN. Justification.

Logical network diagram(s) including addressing and naming

Discussion of routing and switching protocols

Routing protocol denotes to the mechanism by which packets within a network are routed to another network. In our network design for NTN private college, we are using OSPF. We chose this routing protocol due to its modular convergence and ease of management features. For instance, a single area represents a full complete network.

Discussion of security mechanisms

In any computing environment, security that protects computing infrastructure is important. There are millions of network attackers out there who are trying their best to access other people’s computing infrastructure to have self-gain from their vulnerable activities. Since NTN private college handles patient data (which ought to be super confidential), network security has to be implemented. To accomplish this, we are using Cisco ASA firewall to protect such kind of health data.
