Topics• Introduction– About Archdiocese of Beira– Problem Description– Project Description– Project Goal
• Requirement Gathering• Implementation Methodologies• Conclusion• Future work
Introduction• The 21st century is characterized by massive
use of information and communication technologies in almost every lines of work.
• My area of interest falls within associating theoretical and practical studies, and want to extend this to the use of technology in the Archdiocese of Beira.
• The project will covered the steps of data collection, data analysis, and proposed implementation of the network and its services.
About Archdiocese of Beira• The Archdiocese of Beira is a religious
institution, which operates in Sofala Province.• It has the central offices in Beira, Rua Correia
de Brito, 125. • It was founded on September 4, 1940 • The current archbishop is Don Claudio Zuanna.• The Archdiocese of Beira, is organized into two
major sectors - the secretariat of pastoral coordination, and the secretariat of the diocese.
Problem Description• The activity of every organization, in the 21st
century, relies on Information and Communication Technology for its performance and achievement.
• There is no way an organization can operate successfully without a well-structured information communication system.
• Currently Archdiocese of Beira does not have a computer network infrastructure that suits the operations of a religious institution.
Problem Description(Cont)• With lack of a computer network infrastructure,
this institution faces the problems listed below: – Lack of security of computer resources currently
available and connected to internet– Lack of file sharing– Lack of computer resources sharing, such as printers– Vulnerability of resources connected to the Internet
in terms of virus and malware attacks– High costs in the use of paper, and not sharing
resources– Lack of ICT policy for that institution
Project Description
• The core theme of this project is to analyse, design and implement a network communication system for archdiocese of Beira.
• The entire problems highlighted above must be solved within the project.
Project Goal• The goal is to create a network communication
system to improve the operations of archdiocese of Beira.
• This will be done by structuring the network, including all the necessary services and components, build a portal that will change the face of the organization by making it easy for communication in all aspects, involving the most remote users.
Current state of the network infrastructure• As mentioned previously the Archdiocese of
Beira is composed of two major units that are the secretariat of pastoral coordination with approximately 17 departments and the Secretariat of the Archdiocese of approximately 7 departments.

Common aspects to both units• The two separate connections are a financial
burden to the archdiocese. • The other problem is the speed of the
connection. • Most of the time it becomes so slow that can
take up to five minutes to download a simple web page.
• There is nobody responsible for technical issues to ensure quality of services, particularly in computer resources including the internet connection.
Common aspects to both units• The means used by the archdiocese (the two units)
to communicate with other parishes and other constituents are manually written letters, faxes, telephone communication using land lines and mobile telephone, e-mail for pastors and priests who have computers and public e-mail addresses.
• Don Claudio Zuanna, revealed that he created a domain (diocese.beira.org) in Italy before his coming to Mozambique, to streamline the technological needs of an institution he is going to head.
User Needs
• Because we need to create a communication system for the archdiocese, we had to first get the organizations user’s need, which are the following:– User needs
Implementation Methodologies
Network connectivity
• The connection to the internet will use T1 Leased Line Connection or Fiber Optic which is a permanent, dedicated high performance telecommunications network connection which can transport voice and data via a copper or fiber optic connection between a customer site and the ISP’s hub.
• The preferred ISP will be Movitel.
Domain Name and Web Hosting
• The creation of a local-Mozambican domain name which ends with .mz is highly recommended.
• Because the organization needs to implement a network capable of hosting their own web site, we recommend Movitel as the ISP for such services since they provide services from they own fiber connectivity with better performance than other ISPs.
Network cabling
• The network will consist in two parts - wired and wireless.
• For the wired part, the use UTP Cat6 which is an improvement on the cat5 and cat5e is recommended.
• It is a standard cable used in Gigabit Ethernet network connections. This will enable the same connectivity be used for voice in the future.
Wireless Networking• For the wireless network, the use of UniFi
Enterprise Wi-Fi System is recommended.• UniFi Enterprise Wi-Fi System is a scalable
enterprise access point solution designed to be easily deployed and managed.
• UniFi AP indoor models have a soft design and can be easily mounted to a ceiling tile or wall using the included mounting hardware.
• Standard: Wireless Indoor Access Point 2.4 GHz, 802.11b/g/n, 300 Mbps,
Buildings interconnectivity• Because the two buildings are separated by a road
and the total distance between them is approximately 250 meters, we recommend the use of Ubiquiti Pico Station M2-HP 2.4GHz Hi Power 802.11N Outdoor Radio System.
• The PicoStationM2-HP is one of the smallest outdoor 802.11g/n access points and it's also one of the most powerful, with up to 1,000 mW of output power.
• This omni-directional router can provide up to 8 million square feet of wireless coverage.
• It can connect to 802.11g/n devices or, for maximum range and speed, compatible Airmax11n devices.
Routers
• Cisco 3900 Series Generation 2 Router is the recommended router.• The Cisco Integrated Services Routers Generation 2 (ISR G2)
platforms are designed to enable the next phase of branch-office evolution, providing rich-media collaboration and virtualization to the branch office while maximizing operational cost savings.
• These routers support – new high-capacity digital signal processors (DSPs) for future enhanced
video capabilities, – high-powered service modules with improved availability,– multicore CPUs, – Gigabit Ethernet switching with Cisco Enhanced Power over Ethernet
(ePoE), – and new energy visibility and control capabilities while enhancing overall
system performance.
Switches
• For this network infrastructure, we recommend Cisco 300 Series Switches.
• Cisco 300 Series Switches deliver the ideal combination of price, performance, and capabilities in a solution designed specifically for small businesses.
Firewalls
• For security reasons the use a Unified Threat Management (UTM) is recommended.
• Unified Threat Management (UTM) is used to describe network firewalls that have many features in one box, including e-mail spam filtering, anti-virus capability, an intrusion detection (or prevention) system (IDS or IPS), and World Wide Web content filtering, along with the traditional activities of a firewall.
Enterprise Servers
• For servers, HP Integrity rx2800 i4 Server or its equivalent is recommended.
• HP Integrity rx2800 i4 Server is a reliable and secure 2U two-socket UNIX server.
• Integrity rx2800 i4 Server enables workload consolidation and software licensing cost savings through HP Virtual Partitions (vPars) or Virtual Machines (VMs), while HP Insight software and HP Integrated Lights-Out 3 (iLO 3) increase staff productivity.

System Services Implementation
Mail Service• In order to increase the facilities of communications
among parishes and the rest of the world, this service must be implemented as the domain.
• For such a solution Microsoft Exchange Server will be used.
• Microsoft Exchange Server is a mail server, calendaring software and contact manager developed by Microsoft.– It is a server program that runs on Windows Server and
is part of the Microsoft Servers line of products. Exchange 2013 which has the following features will be used.
Web Service
• The web server will be configured using Apache Open Source package.
• Apache is generally recognized as the world's most popular Web server (HTTP server).
• Originally designed for UNIX environments, the Apache Web service has been ported to Windows and other network operating systems.
Print Service
• A centralized print service using a print server will be implemented to minimize cost and administration
• A print server is a device that connects printers to client computers over a network.
• It accepts print jobs from the computers and sends the jobs to the appropriate printers, queuing the jobs locally to accommodate the fact that work may arrive more quickly than the printer can actually handle it.
DHCP Service
• Dynamic Host Configuration Protocol (DHCP) will be the recommended protocol for IP addressing.
• Dynamic Host Configuration Protocol (DHCP) is a network protocol that enables a server to automatically assign an IP address to a computer from a defined range of numbers configured for a given network.
• For this project, DHCP in Windows Server 2012, is recommended.
File Service
• File services provide the opportunity to access data which are stored on central file servers will be implemented.
• File Server Role of Windows Server 2012, is recommended, for it provides a central location on your network where you can store and share files with users across your network.
• When users require an important file, they can access the file on the file server instead of having to pass the file between their separate computers.
Backup and Disaster Recovery
• A Data Backup or simply Backup is the result of copying or archiving files and folders for the purpose of being able to restore them in case of data loss.
• An HP Store Once 2620 iSCSI Backup (BB852A) system will be used.
• HP StoreOnce Backup systems reduce the amount of backup data you need to store by up to 95%, with our scale-out architecture you can pay as you grow to retain up to 10 petabytes of data in a single pool.
Conclusion • Implementation of this system will change the face of the
archdiocese of Beira in many ways:– In terms of, effective communication, – increase productivity, and – competitiveness, – cost reduction in bandwidth consumption, – reusability of IT resources, and – cost reduction on printing.
• The difficulties of communication among parishes and archdiocese will improve because the e-mail address will be used by all of the members of the organization, and the file exchange will also be done electronically, rather than printed way happening nowadays.
Future Work • This thesis has outlined all the implementation strategies,
equipment needs, budget and future works yet to be concluded includes the following: – Physical installation and configuration of the network equipment– Connection to the fiber grade– Recruitment of staff to manage the system– Training of staff and users– The acquisition of various materials network otherwise specified
should be done by experts in computer networks as well as certified providers within or outside the country.
• There should be a policy for ICT in order to settle the terms of use of resources.
• All members of the archdiocese should be trained to understand how the system works and do their best use
