Design Of Network For Study Group With Simple Addressing Solution - An Essay.

In your role as a Solutions Architect at Study Group, you are leading a team of several system administrators. Study Group is a medium sized organisation and is currently expanding its operations.

The company has acquired eight sites across Sydney to accommodate its various departments. You have been asked to design a network by utilizing 10.0.0.0 private IP address. The network should span eight buildings with a router in each building to join the networks. It is assumed that each building will have its own single subnet. Company expects approximately 1600 workstations and wireless devices across all the sites with approximate numbers in each building as follows:

• English school 480 workstations
• Accounting school - 250 workstations
• Transport Office - 130 workstations
• Research Office - 67 workstations
• Sales Office - 40 workstations
• Information technology school - 550 workstations
• Head Office - 90 workstations
• Public wireless access for authorised Study Group’s users up to 600 devices at any one time for entire eight sites.

1. The detailed design of a simple addressing solution (with diagram(s) and step by step workout of the calculations) that leaves room for growth, is easy to administer and has the minimum wastage of available IP address space.
   b. Explain what happens to your design if the number of hosts per network jumps to over 1500 in English, Accounting and Information technology schools.

Currently the company policy does not allow the use of network analysers on the organisational network. You have recently had a team meeting where all the staff are of the view that the use of network analysers can bring more efficiency in troubleshooting processes.

Write a report for the board of directors proposing to allow the use of network analysers for diagnostic purposes in new proposed network architecture. Your report should include:

1. Brief explanation of protocol in the context of communication networks and the role of network analysers. Explanation should include example of a situation where network analysers can be used in the context of Task 1.
2. An analysis of currently available network analyser tools. The analysis should contain:
   i. Benefits, associated costs, ease of usability
   ii. Recommendation from you, as to what tool would you prefer to use and why.

Task 1

a. Detailed design of the network with simple addressing solution

The design for the network has been proposed will follow addressing solution that is simple so as to establish communication within the buildings acquired by the organization. The organization has a requirement for network design is that it is able to connect 1600 hosts. For designing the whole network, private IP address 10.0.0.0 will be followed so that there is proper communication between the devices. According to requirements of the organization, the specific number of workstation required for each building has been mentioned. For establishing communication within devices of the network, a central router will be implemented. Each building of the organization will be assigned with a separate router and switch so as to connect the hosts within the network. The calculation of subnet is done for allocating IP address to the hosts hence there is a requirement to calculate so that those can be accommodated. The technique applied for calculating the subnet is VLSM where some additional IP addresses have also been reserved so as to support future expansion of the organization.

There are a few hazard related with the advancement of the system arrangement and it is required to be agreed to extending ability of the proposed sort out course of action. A true blue cabling plan is required to be taken after for extending the transmission speed and constraining the blockage in the framework. The unused ports in the progressions is required to be weakened with the true objective that the attackers cannot use it for getting to the framework resources (Demuth et al., 2014). A firewall is introduced in the section and the leave purpose of the system with the end goal that the movement can be observed and controlled. Each of the switches are arranged with an alternate subnet and the switches are planned with the help of simple addressing solution so that they communication can be established between them. Access control list is required to be orchestrated on the switch for permitting or blocking access from asserting the framework resources. The center points and the workstations related in the framework are allotted with the static IP address ascertained from the tending to plan to such an extent that the official system cannot be utilized by the representatives with their own use. Servers are in like manner required to be presented for establishing communication within the devices along with supporting expansion of network in future so that increasing demand of organization can be met (Tree, 2014). The establishment of the framework is required to be strong and thus fiber optics interface is used for correspondence for talking with the various branches.

The addressing solution that has been chosen for the network is simple and is made for providing the 2350 IP addresses that are required in various buildings being acquired by the organization. There is a need to configure the routers as per the proposed addressing solution to design the network along with increasing efficiency of the operations within the organization.

Simple Addressing solution

Private IP Address: 10.0.0.0/24

Available IP addresses in major network: 254

Number of IP addresses needed: 2350

Available IP addresses in allocated subnets: 3632

The network analyzer can be presented in the proposed respond in due order regarding division of the data packages and the log development can be obstructed for finding the data stream in the framework. The mistakes in the system is required to be analyzed and relieved for productively build up the system arrangement (Simmons, 2014). A default course is required to be resolved to the switches for trading the data packs and they are required to be orchestrated honestly and framework convey understanding is required to be executed for securing the framework from external access.

With the development in the amount of host per arrangement of the work environment collecting the subnets are figured and the present framework setup is required to be changed in the switches for use of the change. The subnets are figured for the accommodation of the 1500 hosts for every framework and this causes change in the static IP address of the hosts, unblocking the ports on the switches and outlining the switches with the new IP address and the subnet cover. Various subnets are made for the framework and for development of the host there are differing strategy that can be associated however the monetarily sagacious course of action is the reconfiguration of the switches and the other gear contraptions related in the framework. Some IP bits are kept for conceivable later utilize and the host formula is used figuring the new subnet and suit the extended number of hosts in the framework. The calculation work and the result is given underneath:

The tradition essentials in the framework are HTTP, FTP and SMTP. The HTTP is the hypertext trade tradition, SMTP is the Simple mail trade tradition and FTP is the File trade tradition. The HTTP tradition would empower the structure to approach the web connection and framework would be able to go on the web. In addition, the FTP tradition would enable the structures in draw in to exchange records inside the system (Hale & Stanney, 2014). The SMTP convention would enable the fragments of the framework to pass on among them capably. Moreover, the correspondence amidst the staffs of the association would in like manner be to a great degree gainful and they would have the ability to exchange messages among themselves.

Study Group is an organization that is medium measured and they are hoping to grow their operations. Thusly they are required to remake the system structure for their organization. The association methodologies do exclude the use of network analyzers in their framework disregarding the way that the network analyzers are to a great degree beneficial for the association to do their techniques. In like manner, the network analyzer would moreover empower the association to perceive the faults that are existent inside the framework (Mahgoub & Ilyas, 2016). The data about the traditions that are being utilized as a bit of the system is given underneath.

Explanation of design for increase in number of hosts per network

The system analyzer is incredibly important for the framework and it gives diverse sort of workplaces to the framework. The system analyzer fills assorted sort of requirements for the framework and the standard parts of the device are:

• The tool plays out a phenomenal examination of the system and furthermore the screens the system productively.
• The network analyzer assumes the part of a security framework for the system.

The Wireshark tool can be utilized as a part of various arrangements by the system. The instrument goes about as a network analyzer for the system. They are additionally utilized to monitor the system. They perform examination of the information and the records that streams all through the system. Following the packets is one of the procedure that is performed by the analyzer instrument (Pathan, 2016). Wireshark is one the best programming that can be used as a network analyzer similarly and the thing is to a great extent commonly available and powers a noteworthy high arranging in the market for the division of network analyzer.

The system analyzer tradition is incredibly beneficial to the framework. The device besides helps in the examination of the structure and performs seeing of the frameworks. Thus, they secure the frameworks shape from external attackers. It bolsters a broad assortment of conventions, for example, the IP, Bit Torrent, AppleTalk and DHCP. In like manner, with each of refresh, the tool is revived and another tradition is incorporated to the application a standard schedule. The network analyzer supports around eight hundred and fifty conventions.

The Wireshark Network analyzer is a device that is permitted to use and from this time forward it doesn't require any additional cost for the association to endure. The cost for the use of the structure is basically invalid. The cost for the wire of the analyzer on the structure framework is to an extraordinary degree superfluous. In this way, the related cost for the analyzer is nearly nil. For utilizing the instrument the base necessities of the structure are: 60mb space on the hard drive, a processor that has a clock speed of around 400 MHz. In addition the Network Interface Controller is moreover endorsed.

The recommendations for using the tool for analysis of the network is provided as below:

Understanding information: The client of the system ought to have the capacity to comprehend the kind of information and furthermore the stream of the information through the system. This would bring about better treatment of the network analyzer.

Understanding arrangements: The setups in the system ought to likewise be used productively by the client and they ought to likewise have the capacity to see the real functionalities of the system.

The chosen tool for analysis of network is suitable in context to the proposed network design. In task 2 of the report, the discussions have been provided on the tool that has been chosen for analysis of the network. Study Group is an organization that is medium measured needs to grow their operations. In this way the organization is required to recreate the system structure for their organization. The activity of actualizing a system configuration has been endowed to me. The strategies being adopted by the organization do prohibit the utilization of system analyzers in their structure dismissing the way that the system analyzers are significantly beneficial for the relationship to do their procedures. In any case, the staffs are need to know the benefits that will be provided by the tool for network analysis.
