NETWORK DEVELOPMENT CAPSTONE PROJECTGRADUATE SEPTEMBER 2005 • This is the final quarter course of Information Technology – Computer Network Systems program for Associate of Applied science Degree. • A mandatory "Capstone" project will allow student to work in teams to provide a business solution to an external organization, which example of is given in Network Development CASE STUDY. • The capstone project allows students to apply the knowledge and skills acquired in their courses to the work environment. • This project is completely individualized; students are encouraged to select work-related projects that are of particular interest to them and that will result in professional growth and benefit the organization.

WAN/LAN Design & Hardware Joanna Buraczynska
Project Idea • Existing Process versus Future Growth • Connectivity Between all Locations • LAN/WAN Hardware • LAN/WAN Design Goals • Project Standards and Procedures
Life Cycle Diagram • Analysis, • Planning, • Implementation, • Review.
Existing Process • TTI WAN link up all 4 school sites with the Main Campus for the purpose of delivering and exchanging data, storage plus run applications • Each building provides a MDF room (a central point to which all LAN cabling is terminated) which acts as a POP-point of presence as well to provide an Internet connection • Star Topology is implemented • Each campus has 4 wired computer labs with 31 student workstations and 1 instructor workstation in each lab • CAT 5 UTP cable run are tested end-to-end for 100Mbps capacity for servers and 1Mbps for hosts • The LAN is based on Ethernet LAN switching
WAN Growth Requirements Connection type with other branch offices • Frame Relay Network – More cost effective than dedicated leased lines. • All Internet connections will go through HQ • ISDN WILL BE REMOVED Bandwidth requirements • Hosts-100 Mbps and Servers-1 GB Cable Type • The Backbone would be a combination of fiber –optic and CAT6 for Gigabit transmission • CAT5e for the most systems to their immediate network junction
LAN Growth Requirements Quantity of computers for each campus • 1 student workstations and in each classroom will be removed • 2 admin workstations will be connected to the network in LRC • One MDF will support WAN connection plus 12 admin offices, 4 labs, 4 classrooms and LRC. • IDF room in new Houston West campus will also support WAN connection plus 6 labs, and 6 classrooms. • For Houston West 2nd floor 2 labs and 2 theory rooms will be placed instead of admin offices, so total will be 6 labs plus 6 theory rooms
Major Pieces of LAN Structure are Broken into Three Unique Categories of the OSI Model Layer 1 - Physical Layer • Includes wire media type such as CAT5 UTP and fiber-optic cable along with EIA/TIA 568 Standard for layout and connection of wiring schemes. Design Goal • Build this layer of the OSI model with speed and expansion capabilities Layer 2 - Data Link Layer • Includes selection of Layer 2 devices such as bridges or LAN switches used to interconnect the Layer 1 media to for a LAN segment. Devices at this layer will determine the size of the collision and broadcast domains. Design Goals • Create a concentration point within the MDFs or IDFs where end host can be grouped at Layer 1 to form a physical LAN segment. • Install LAN switching devices that use micro segmentation in order to reduce the collision domain size. • Create a point (at Layer 2) of the topology where users can be grouped into virtual workgroups (VLANs) and unique broadcast domains.
Major Pieces of LAN Structure are Broken into Three Unique Categories of the OSI Model –cont. Layer 3 - Network Layer • Includes selection of layer 3 devices such as routers which are used to create unique LAN segments and allow communication between segments based on layer 3 addressing such as IP addressing. Design Goals • Build a path between LAN segments that will filter the flow of data packets. • Isolate ARP (Address Resolution Protocol) protocol broadcast • Isolation of collisions between segments. • Filtering of Layer 4 services between segments.
Project Standards and procedures • The WAN as a whole will be connected with a series of routers that will replicate all information from server to server • Campuses will be connected by leased T1 lines and will run at a constant speed of 1.54Mbps • Staff and students will have a 24/7 access to the Virtual Library at home • The network will run at a constant speed of 100Mbps • The WAN equipment will be provided by Cisco Systems, Inc. • Dell, Inc. will take care of the LAN hardware such as servers and workstations • All printers will be provided by Hewlett-Packard development Company, L.P. • TTI will be protected from viruses by top of the line anti-virus protection by Symantec Norton Anti-Virus and the firewall will block all unauthorized access attempts and redirect them to the TTI website • Incremental backup will be conducted every night , plus full backup completed once a week on Saturdays
Domain Structure – Server & Workstations Jessica Mucia
ABOUT ACTIVE DIRECTORY • A network service that identifies all resources on a network • Makes resources accessible by uniquely identifying them • Stores information about users and groups, workstations and servers, policies and scripts, printers and queues, switches and routers, databases, security policies, all in a hierarchical fashion • A directory service is not a general-purpose database - You would not implement a directory service to manage a point-of-sale system in a chain of stores - But you would consider implementing a directory service to manage the salespeople who log on at the point-of-sale terminals
Understanding Active Directory • A directory service compiles information about objects of interest in the world and dispenses that information when given a request. The Yellow Pages or a library card catalog are examples of a directory • People like to have their information classified for easy retrieval. For instance, the Yellow Pages has categories like “Theatres or Movies” and “Restaurants - Italian,” and a library card catalog classifies items into “Books – Fiction,” or “Books – Nonfiction,” or “Periodicals.”
WHAT ACTIVE DIRECTORY PROVIDES • Scalability – Provides an efficient mechanism to store objects and multiple indexes for fast retrieval of information • Extensibility – Provides object classes for domains, OUs, users, groups, and printers. It is extensible through a schema which allows for information to be easily retrieved • Interoperability – ADSI (Active Directory Service Interfaces) provides a single, consistent, and open set of interfaces for managing directories • Replication – Handles queries and updates. Users are able to access information anytime, anywhere from within the domain. • Locater Services – DNS and global catalog provide an easy method of retrieving information
LOGICAL STRUCTURE • The basic unit of logical structure in Active Directory is the domain • All network objects exist within a domain and each domain stores information only about the objects it contains • An organizational unit, or OU, is a container used to organize objects within a domain • A tree is created when you add one or more child domains to an existing domain • Domains within a tree share a contiguous namespace and a hierarchical naming scheme • A forest is the arrangement of one or more independent domain trees
PHYSICAL STRUCTURE • A site is a combination of one or more IP (Internet Protocol) subnets connected by a fast and reliable link • The main purpose of a site is to physically group computers to optimize network traffic • A single domain can cover one or more geographical sites, and a single site can contain user accounts and computers from multiple domains • Sites confine authentication and replication only to the devices within a site • A domain controller is a computer running Windows 2000 Server and stores a replica of the domain directory • Since a domain can contain one or more domain controllers, each domain controller in a domain has a complete replica of the domain’s portion of the directory
AD DOMAIN DESCRIPTION • Root domain – TTI-Tech.edu at the main campus • Each other campus is a child domain of the Main Campus • Administrative and Student groups and users will be created on each child domain
SERVER ROLES • ADMINISTRATIVE SERVER – Root Domain, DHCP server, DNS server, Application server • STUDENT SERVER – DHCP server, DNS server • LINUX SERVER – Anti-Virus server, Print server, DNS server, RADIUS server • WEB SERVER – Virtual Library server, E-Mail server • FTP SERVER
SERVER & OS DISTINCTION • There are a total of 5 servers at the main campus – Administrative, Student, Linux, Web, and FTP server • Each other campus has 2 servers, one Administrative and one Student • The operating system for the main campus is Server 2003, San Antonio will be using Linux, and Austin, Dallas, and Houston West will all be running Windows XP
