Executive Summary
Colour Ability Corporation (CAC), one of the small sizes promising marketing and advertising company based on Brisbane CBD, wants to upgrade their Information and Communication Infrastructure (ICT). CAC has total four departments (marketing, advertising, design and photography, and HR and accounting) and one satellite campus situated in Sydney. This ICT renovation should take place in a new office building where four separate floors are dedicated to four distinguish departments of CAC. Main aims of this renovation processes are:
Upgrade of the legacy work-station Hardware and Software depending on the requirement of working groups.
Implementation of secure private email services.
Adaption of the latest, high-speed and secure file sharing mechanism.
Creating an efficient system set up for video file editing.
Installation of the Wireless access points to support local node mobility.
Installation of heavy-duty printer and copier for general staff and dedicated color laser printers for the managers.
Proper IP subletting using available Private and Public IP range.
Reusing existing network components as much as possible to make the design cost-effective.
Introduction
This project proposal document is intended for the Information and Communication Infrastructure (ICT) renovation of the Colour Ability Corporation (CAC). It identifies all the technical needs of CAC to provide a current state of the art ICT infrastructure which suffices the need of every working-group of the organization. In the current scenario, CAC is using a set of legacy systems which are computationally not adequate for most of the employees of the organization. Moreover, CAC needs a proper mechanism for file sharing and document printing. This project proposal document identifies all the technical needs of the organization (software and hardware) and proposes a logical topology to fit all the components efficiently. This document is segmented into two parts; the initial part of the report identifies and documented all the technical needs of the organization, and the latter part of the document deals with the installation procedure. These two parts will help to execute the future installation procedure in a modular way. Further organization of the document is as follows: Chapter 3 covers the requirement analysis part as workstation specification, copier-printer specification, network logical topology, internal network service specification, and wireless access point installation plan. Chapter 4 addresses the installation plan, sub-netting & IP assignment (Wegner J.D.), security plans are coming under this part. Budget summary, Recommendation, and Concluding remarks can be found out in the last chapter of this document. Reference and Appendix are also present at the end of the documentation part.

Requirement analysis & specifications
This part of the document highlights all the technical requirement of the project and their technical specification. Prior to the actual implementation this requirement specification document helps to derive the project budget and creates a progress plan for the implementation team. This part of the document is segmented in six different activities as enlisted below.
Activity List:
Workstation specification
Copier-printer specification
Network logical topology
Network connectivity plan
Internal network service specification
Wireless access point installation plan
Workstation specification
In the organization, there are total three types of users as general users, graphics editor, and film production unit. System requirements for these three categories along with the server specification are given in the following Computer System Planning (CSP) forms. In the existing system, users rely on AMD Athlon 64 x2 dual-core processor with 2GB RAM. Without eradicating existing systems, we can reuse them for general users after making few hardware upgradations. This will help to minimize the implementation cost.

Network logical topology
This part of the document demonstrates the physical topology of the network. Existing network contains 14 10/100 MBps switches. These switches are needed to be replaced to get high-speed network connectivity. Moreover, this proposal connects the Melbourne office using VPN (Henmi A.) connection as it is the cost-effective, secure and scalable approach. In the following table, we have enlisted all the network components which are required for the implementation of the network topology.

VPN Connection
Network connectivity plan
For the Internet service and VPN connectivity with the Sydney office CAC need ISP services. To make the services, reliable CAC must choose redundant ISP services. Primary ISP must provide public IP-range and DNS (P. Cifani) services along with internet connectivity. Other ISP (Secondary ISP) must provide redundant connectivity during the downtime of the primary ISP. A comparative analysis of two popular ISP of Brisbane is given in the following table.

Designing justification
Are wired connections required? Number:
Wired connection is required because it is more reliable than the wireless connection.
Number of connection= Number of computer + Printer count = 80 + 9 =89 (Aprox)
Wireless standard Choice of a/b/g/n/ac
IEEE 802.11 g is recommended. A firewall setting is required to ensure internal resource protection.
ISP connectivity required? Yes/No
ISP connection is required to get an Internet connection, Public IP range, and DNS service.
DSL connection is preferable
Internal or external modem required? Yes/No (if Yes, then type of modem)
Modem is not required
Battery backup required? Yes/No
Battery backup is required to make the ICT fault tolerant.

Data Security Issue
To ensure data security and data isolation we should use private and public IP together. We also need DMZ configuration for the proper data isolation and data security. Public IP is globally accessible IP addresses. The publically accessible resource must acquire public IP addresses. Security threats are very high on publically accessible devices, so we must keep all the business logic and sensitive data in the internal node of the organization. These internal nodes must have private IP so that they can be accessed seamlessly within the organization. DMZ configuration creates a separate layer of node isolation using the firewall rules. Firewall rules ensure that the internal node can be accesses external world using some well-known protocols through NAT (Walter G.) but internal node should remain inaccessible for the external world.
Conclusion
As a concluding remark we can say that the given ICT renovation plan can suffice all the needs of the organization using the least cost budget. Specifications of all major components are present in this document along with physical topological plan and IP distribution. This plan will act like a future roadmap for the implementation team. From the requirement specification document, we can easily derive the project cost. This document is also helpful for the project risk identification and risk identification plan design. This plan also considers the security needs of the project and the design of the project inherently satisfies security needs. This plan makes the recommendation for the computer hardware updradation which will make the video processing task and other organizational tasks easier.
