Question

In your role as a Solutions Architect at M2M Solutions, you are leading a team of several system administrators. M2M solutions is a medium sized organisation and is currently expanding its operations.

The company has acquired six sites across Sydney to accommodate its various departments.You have been asked to design a network by utilizing XXXXXXXXXXprivate IP address. The network should span six 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 1200 workstation across all the sites with approximate numbers in each building as follows:

Finance Office - 260 workstations
Transport Office - 130 workstations
Research Office - 120 workstations
Sales Office - 40 workstations
Information technology - 520 workstations
Head Office - 60 workstations

TASK 1 -Write a 1000 words (+/- 10%) report explaining:

a.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 1,024 per building.

TASK 2 - 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 an 800 words (+/- 10%) 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:

a. 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.
b. 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.

(The reports should be targeted towards your audience i.e. the board of directors who may not be technologically savvy. Therefore the report should be easy to read and contain step by step overview of the design that includes calculations and assumptions. Additionally, the report contencts should be logically, systematically and succinctly structured to create a cohesive and coherent analytical piece of work, using formal academic language and should adhere to grammatical conventions.)

Rationale

This assessment aims to assess the following learning objectives of this subject:

be able to analyse IP addressing requirements and design an addressing scheme;
be able to analyse the requirements of IP routing and choose appropriate routing methods;
be able to demonstrate how internetworking devices obtain their network configuration;
be able to explain how data flows through the internet; and
be able to ascertain and evaluate selection of applications and protocols for transferring data across the internet.

1. Executive Summary  
The aim of this report is to submit a simple network design solution to board of directors and convince 
them to implement the network analyzers in the network. The M2M Solutions proposes designing a 
network for their newly acquired six sites across Sydney. These six sites act as a business expansion for 
M2M solutions and hence require a scalable networking design and services. The sites have to be well 
connected with the private network address of 10.0.0.0 with distinct networks (subnet) at each site. All 
the six sites together accommodate approximately 1200 workstations. Each site accommodates a router 
to connect with different subnets. It is assumed that the new networks to be designed support all 
network services. Examining the requirements, we can see the sites are marked as finance office, 
transport office, research office, sales office, Information technology and head office with 
260,130,120,40,520 and 60 workstations respectively. As a solution architect I would design the network 
by considering all the requirements gathered and present the simple network solution for the sites. The 
main purpose of this report is to design a network with minimal wastage of IP address space. Following 
the network design, we also evaluate the company policy to understand the reason for not using the 
network analyzing tools in the M2M organization network. From the collected policy information 
analysis we would suggest the benefits of using the network analyzers in the organization network in the 
context of troubleshooting. This report summarizes the protocol and network analyzer that can be used 
in the organization based on different factors such as cost, usability, reliability and scalability.

2. Designing addressing solution 
 
2.1. IP version 4 address space facts 
Considering the requirement of 10.0.0.0 range address, we use the IPV4 addressing scheme to design 
the networks for the organization sites. The hierarchical addressing scheme is used by the IP version 4. 
To begin with, the IP version 4 address is 32 bit in length. According to the classfull IP concepts the 32 bit 
IP address space can be divided into network bits and host bits as shown in the following figure.
The portion that consists of the network bits is referred as network portion. Similarly, the portion that 
contains the host bits is referred as the host portion of an IP address. The network portion of the IP 
address remains constant. Based on the network part the IP addresses can be classified into Class A, 
Class B, Class C, Class D and Class E. Out of the mentioned classes, the class D is reserved for multicast 
and class E is reserved for unicast. The default length of network bits of classes A, B and C are 8,16 and 
24 bits respectively. The default length of host bits of classes A, B and C is 24, 16 and 8 respectively.
