Background Information: Credit Crunch
Credit Crunch (CC) has been operating a debt recovery service for banks and other financial
lending institutions for 10 years and is looking to upgrade its system.
Due to the collection of personal and financial information, data maintained by CC is
considered highly sensitive. As in any business payroll and financial information is
considered sensitive to those inside as well as outside the organisation.
Currently, CC leases a floor in Sydney for its head office, staff and (security) are:
1. 3 x Executive Managers (Full Access)
2. 5 x Accounting /HRM (Access to Internet, Microsoft Exchange, Financial System, and Payroll
System)
3. 5 x Account Managers (Access to Internet, Microsoft Exchange, Customer Relation
Management System and Debt Recovery system)
4. 2 x Information Communication Technology (Full Access)
5. 3 x Call Centre Supervisors (Microsoft Exchange, Debt Recovery System)
6. 80 x Call Centre Operators working shifts on 40 workstations (Microsoft Exchange, *Limited
Debt Recovery System)
Executive Managers and Account Managers may bring the own devices and connect to the
network via a wired or wireless connection. All other staff work only on wired workstations.
The core system of the business is the debt recovery system (DRS). The DRS contains two
separate software systems operating on different servers:
1. Predictive Dialler Software (PDS) – is connected to the company’s telephony board and
makes calls to debtors based on a list of phone numbers and debtor ID’s imported each
morning. When a call is answered it’s forwarded to a phone at an available operator’s
workstation and a message is sent via DCOM of the Debtor ID to the client of the Debtor
Database System at that workstation.
2. Debtor Database Software – is a client / server DBMS. When a client receives a DCOM
message from the PDS it requests data from the server via TCP/IP pertaining to the Debtor
ID. The server sends the requested data to the client who modifies and saves the data. The
operator then selects whether they are ready to receive more calls or take a break and the
message is sent back via DCOM to the PDS. The server uses timed backup to send
modifications of the database at regular intervals to an offsite location via TCP/IP.
Given that the person being called has already answered the phone prior to it being passed
through to the operator, time is critical, both in terms of the operator answering the phone
and having the debtor’s data accessible to the operator.
* Limited Debt Recovery System – Call Centre Operators should only have access to records
forwarded to them by the server but not access to the full debtor’s database.

Assignment Task
You have been engaged as a member of a network planning team by a member of the
executive management of Credit Crunch to prepare a business report on a network plan for
their business. Although this is a business report it is also an academic assignment. All
theory must be referenced, and all arguments put forward, supported by scholarly
references.
As your target audience includes executive businesspeople, who have extensive business
experience, but may have limited ICT knowledge, the report needs to explain why your
recommended networking technologies/solutions are the most appropriate and how they
will benefit their business. You may need to compare your recommendations with other
available technologies.
Specifically, your report must address the questions in topic 1 and one of the questions in
Topic 2.
Topic 1 – Network Upgrade
Many of the networking devices are ageing and management has inquired about upgrading
the entire network infrastructure. Whist their ISP still operates on IPv4 (IP
120.154.191.1/24) they are keen for the new network to operate (at least internally) on
IPv6.
Topic 1.1 Structured Cabling Plan
You are to prepare a new cabling plan for their existing operations. You need to explain the
key components included, as well as the recommendations for cable types and connecting
devices.
Topic 1.2 Network Topology Diagram
You are to use Cisco Packet Tracer to build the proposed topology and include a screenshot
of the topology in your report.
Topic 1.3 IP Addressing
Based on your topology you are to prepare an IPv6 addressing plan. This plan should
address the range of IP addresses for any subnets you define and how the system will
manage IP addressing. Your discussion may include, but not limited to DHCPv6, switching
tables, routing tables.
Topic 2 – Choose ONE of the following topics
Management have also requested information about the following topics. As part of the
networking design team you can choose which question to address.

Topic 2.1 Additional Site
Credit Crunch is looking to open a branch office in Melbourne with similar numbers of staff
with the exception that Accounting / HRM staff will remain in Sydney.
Management have asked for your recommendations for connecting the two sites.
How would your response change if they decided to open a branch in Singapore?
Topic 2.2 VOIP
The current system uses a telephony system which costs considerable money in call costs.
Management have asked you to investigate using Voice Over Internet Protocol (VOIP) for its
call centre. What issues should management consider in deciding? What are your
recommendations? Does this alter your proposed network topology?
Topic 2.3 Redundant Servers
Currently the office runs one database server for it’s DRS. If the server crashes (which it’s
known to do) all work stops until the server and workstations are rebooted. Management
have asked your opinion on running two or more database servers. In terms of networking
how might this be achieved? How will you achieve database consistency (you may want to
investigate CAP Theorem)? How does this alter your proposed network topology?

Assignment Advice
This assignment will take several weeks to complete and will require a good understanding
of data science and management for successful completion. It is imperative that students
take heed of the following points in relation to doing this assignment:
1. Ensure that you clearly understand the requirements for the assignment – what must be
done and what are the deliverables.
2. If you do not understand any of the assignment requirements – Please ASK the course
your tutor.
3. Each time you work on any aspect of the assignment reread the assignment
requirements to ensure that what is required is clearly understood.
4. There are 10 marks for Report Formatting. You are ICT students so it is expected that
you can format a word document, so these marks should be a gift. Don’t be
embarrassed if you’re having difficulty ASK your tutor.
5. In practice, you often have clients that you can converse with to clarify queries you may
have, which is ideal. Likewise, you are often given system briefs and must make
recommendations about system features based on assumptions and your expertise. In
this assignment you’re probably going to need to make assumptions, if you do make
sure you note these.
6. Topic 2 was designed in lines with the university policy of self-directed learning, there’s
no best question to answer, simply choose one that is of interest to you and answer to
the best of your ability.
7. There are no marks in the marking sheet for referencing. Be aware that arguments not
supported by references will earn few marks if any. Theory presented without
references may result in an academic misconduct charge. Whenever you write
something you should think how do I know this? If it’s because you undertook primary
research you can reference your research, in all other cases you need a citation of where
the information was obtained from.
