Advanced Network Design

Introduction

The report will emphasize the usefulness of network requirements bringing in integrity in the functionalities of an organization. In here there will be designing of a WAN structure by the use of Cisco Packet tracer, and as a network engineer, there will be explanation regarding the requirements needed for the WAN structure to make the organization work as per recent technological requirements and thus gain profit. The whole business has two branches one3 in Sydney and one in Melbourne having different departments like Customer Services, IT, sales and marketing also additional departments like Human Resource and Accounting.

Task 1

In order to gather (user, application, and network requirements) different techniques i.e. Interviews and questionnaire are used. Create a questionnaire to get application requirements. The questionnaire must have at least 10 questions. Describe the purposed of each question and categorize the questions whether it is focused to user, application or device requirements. Record possible answers to use in next task.

In designing a network there should be clear insight about the requirements of the clients, as well as understand the necessity of the employees that will access the servers and the process they will handle. Therefore, designing should be in such a way that the employees can connect and satisfy the needs of the client through the network server[1]. The purchase of technology will be done in the designing of the WAN structure in this report, But, in purchasing the technology there must be availability of training and educational programs so that the employees can work through it in satisfying the needs of the customers.

Aim: to get a required solution to helps succeed the organization, and the decided requirements meet the technology.
There was certain way of connecting with the clients, so interviews were taken from different clients. The questionnaire that will be provided to the client are as follows, which will help in getting their views and opinions. The management requirements will be asked from the clients as well as the network issues that will help in making a good structure of WAN.

Questionnaires

Who are the key stakeholders needed in the designing of the network?

What will the best fit technology in designing a wan structure?

Will the new technology implementation help in developing the environment and integration of the wholesale business?

What will be the timeline requirements in completing the network design?

What will be the financial investments in designing the new network?

What characteristics must be included in the new network design like redundancy, speed of the server, investments. Performance of the network, capacity etc.?

State the cloud system type that the new network will use, public, private or hybrid?

State the drivers that is necessary to design a new network?

State the barriers related to the new network?

What will be the outcomes related to the setting up of new network design?

Will this help in business growth?

User opinions

User 1

An installation of WAN in an organization is very necessary to operate the LAN, in the particular business scenario the wholesale business must set up their WAN so they can have good connectivity in the future process. The two departments can interact with each other usi8ng the installation of WAN so using the ISDN Technology will help in making the requirements successful as it will help in developing the integration among the two departments. WAN is necessary in connecting two branches of the same organization. The connection of hubs, switches will help in disorienting the traffic in the router and it will also help in passing packets to the destination.

User 2

The ISDN technology is the most preferable technology given the requirements of the report, as whole sale business needs the connectivity in passing information or giving users to access the information or know product details. The key stakeholders for the WAN installation are the customers, employees as well as the higher authorities of the organization. Employees being the key stakeholders of the origination as they will help in operating the servers and helps customers connect with them creating profit maximization in their organization.

User 3

In implementing the ISDN technology normal physical cables will not be much of benefit, the security privacy is also necessary while connecting the branches of different demographic locations[3]. To implement a successful WAN technology there must be use of Dual homed topology which will connect the hub routers of different organization located in different area. Though they are complex infrastructures, it helps in connecting various locations through the hub router implementing the WAN cloud.

Task 2

1. Design a WAN structure of the business showing all devices such as routers, switches, links, etc. by Using a relevant network designing software. Draw a diagram to illustrate your high-level design.
The WAN Structure will help in determining the LAN and connecting different devices to the various locations[2]. As the two have various departments that will interconnect with each other. A Design has been made using the CISCO packet tracer, which will be later defined step by step to understand the connectivity. The structure is given below:

This will help in understanding the network which is deterministic form and connecting two different modules. This will also help the network designer to determine the data traffic[6]. This provides the redundancy of the network, and reduces the complexity so that new functional modes can also be applied. In the later mode this architecture will help in modification which will tend the network designer to not change the base and add new feature to the already existing network design,

Figure 2: The high level design for WAN network

The figure describes the large business network which will connect the various sites as well as give access to different users. The wan is generally operated by the service provider, this network also helps the organization to give employees to communicate with the business networks. The implementation of ISDN technology will help in continuous connection, and connect the other network with telephone lines with high bandwidth and provision of IP services to providers.

2. Determine Network Addresses by using the subnet 192.168.P.0/24, where P is your group number. You also need to use Variable Length Subnet Mask (VLSM)

technique whilst creating the subnets and allow 30% for possible future expansion.

Figure 3: The diagram representing three subnets using VLSM

In this particular aspect we need to add 2 bits which represent two host addresses. The subnet mask used for this connection will be 255.255.255.252. The original network will have the IP Addresses of 172.16.2.0/ 24, which can be later changed to 192.168.128.0/24[4]. The table will represent using VLSM by using 30-bit mask on the subnet of both the IP addresses given.

3. Explain the technical aspects for the choice of choosing the specific routers, switches, hubs, application, cables and servers
The hubs, switches and routers will be connected with ports and plugged in with cables to create a high network connection. The necessity of the hub will help in connecting the two devices in the various locations. The figure shown below shows the connectivity between two devices.

Conclusion

In the following report there has been enunciation of the utilizing of the networks which can connect two branches of the respective whole sale business that it represented in the report. There will be many users for the accession of such network which have been mentioned. A Survey has been done where there is 10 questionnaires given in respect to the utilization if WAN in creating interactive business environment.
