Network Upgrade In order to resolve network related problems The Airframe Corporation (TAC) has decided to upgrade the existing network consisting of a mix of Token Ring and shred Ethernet hubs to a switched Ethernet network. The purpose of this paper is to discuss several aspects of the project plan for the upgrade. This discussion will be made in threes sections. Section one will include project definition, while section two will deal with work breakdown structure and estimated schedules, and section three will cover costing and risk analysis. The project definition will include a background and statement of need, project objectives, the mission and goals or the project, the project approach, the project organization, and a task responsibility matrix. The work breakown structure (WBS) will consist of a WBS chart, a task flow and critical path, a project schedule, and project reporting. The costing and risk analysis will contain a cost plan, a project baseline, performance measures, project evaluation and reporting, and project termination. Background and Statement of Need The project team has identified several issues with the current network infrastructure. The first is the availability and cost of token ring hardware. Ethernet is the dominant network topology and is included on many devices at no cost. Equipment with token ring interfaces can be found but are much more expensive. Another problem is that the current hardware is about 10 years old and is experiencing increased maintenance costs. Another problem is that the majority of the existing cable plant does not meet minimal category 5 standards. Project Objectives The project has been budgeted $200,000 for cable installation, labor and hardware and the timeframe for the project should not exceed six months. The network upgrade should be designed to support the companies needs for a minimum of seven years without major rework. The project will need to have minimal impact on the network operations, as a result much of the work will need to be accomplished after-hours or on weekends. Mission and Goals of Project The goals of the project are: • Increase network availability to 99.999%. • Complete project within budget. • Complete project on time. • Upgrade category 3 cable plant to category 5e or better. Project Approach The project manager will assemble a team of individuals with the appropriate skills. Network engineering will design and build the network. A cable vendor will be selected by network engineering. Platform engineering will upgrade clients and desktops. Networking engineering will be responsible for selecting an equipment vendor, designing the network, locating a cable vendor, and identifying cable runs that need to be replaced.
A work breakdown structure is a key project deliverable that organizes the team 's work into manageable sections. The Project Management Body of Knowledge. defines the work breakdown structure as a "deliverable oriented hierarchical decomposition of the work to be executed by the project team”. Basically the work breakdown structure is something that is put together which defines the scope something that project team can understand. On the other hand, project requirement is kind of a document which tell management, what has to be produced and the exact date of completion. It also is based on responsibility factors. Requirements are the expectations which the product need to fulfill. Requirements are collected from the customer, stakeholders and Sponsor.
The first issue is that conversation for upgrading existing networks from 1-GE to 10 GE, 40 GE, and 100 GE. For large enterprises that already deploy one solution, it may be difficult and costly to go from 1 to 10 GE. This is because they would be forced to reorganize and get rid of existing calming. Though with the new cabling that would be installed there would, in the end, be less, it would be expensive to reorganize, reframe, reconnect networks and require manpower to do such tasks. Compatibility between these GE’s as well matters as without the latest version is compatible with the previous issues could arise across networks and successfully transferring data. Meaning that there could be a loss of data if there is not a secure connection across networks.

Token ring networks have since declined in usage and the standards activity has since come to a standstill as switched Ethernet has dominated the LAN/layer 2 networking market.
Kent Beck, the project leader will find using the WBS to make complex projects more manageable as it is designed to help break down projects into manageable chunks that can be effectively estimated and supervised. By creating a WBS include several benefits. For example it can help assist with accurate project company, helps with assigning responsibilities, shows the control points, project milestones, and allows for more accurate estimation of the triple constraint (cost, risk, and time) therefore helping to explain the project scope to stakeholders.
Sending data through the internet efficiently has always posed many problems. The two major technologies used, Ethernet and Asynchronous Transfer Mode (ATM), have done an admirable job of porting data, voice and video from one point to another. However, they both fall short in differing areas; neither has been able to present the "complete" package to become the single, dominant player in the internet market. They both have dominant areas they cover. Ethernet has dominated the LAN side, while ATM covers the WAN (backbone). This paper will compare the two technologies and determine which has a hand-up in the data trafficking world.
Databases are becoming as common in the workplace as the stapler. Businesses use databases to keep track of payroll, vacations, inventory, and a multitude of other taske of which are to vast to mention here. Basically businesses use databases anytime a large amount of data must be stored in such a manor that it can easily be searched, categorized and recalled in different means that can be easily read and understood by the end user. Databases are used extensively where I work. In fact, since Hyperion Solutions is a database and financial intelligence software developing company we produce one. To keep the material within scope I shall narrow the use of databases down to what we use just in the Orlando office of Hyperion Solutions alone.
In communication networks, research was performed on Fiber Optics Local Area Networks such as Fastnet, Expressnet, D-Net, U-Net and Token Ring as they are key networks for factory automation. This leads to interest in modelling and testing of High Speed Networks, which is paramount for the successful development of multimedia systems.
These are the usual questions asked at the start of any project, and the answers are the building blocks of project management - defining what we want to do and working out the best way we can do it. When carrying out a project it is important for the project manager to decide on a method of undertaking the project. There are a large number of different methods that can be adopted, these are called project methodologies, they can be used to assist in the success of a project, the chosen methodology will determine how the project is initiated and also executed until completion.
Understanding network topology can tell one a great deal about installing or expanding a network. At its basic level, the topology of a network refers to the way in which all its pieces have been connected. That is, it refers to the layout of the computers, printers, and other equipment hooked to the network (TechTarget 2006). Because cables connect computing resources together for a network, network's topology is also a function of the way in which the cabling is organized, whether it is arrayed in three basic physical topologies available to LAN designers:
The all projects have a several main charachteristics such as : 1.Each project has beginning and ending, (however beginning could be unclear but it must/should be agreed on what does it means for them), 2. Every project is unique by itself and it also produces a unique outcomes. It could be tangable like bulding , goods and other products or intangible like a new internal rules and responsibilities of the employees of the organisation (factory) .
Assigning the precise amount of network capacity in the right place at the right time is no simple task. Network Planners cannot afford to overbuild, as this would consume scarce investment resources that could be better used elsewhere. They also cannot delay expansion as this may result in poor service to customers and under-utilize other network assets. A balanced approach is needed in order to meet the rapidly growing and changing traffic demands. Advanced network planning and design software provides benefit to network planners in the following ways:
The Database Management System (DBMS) is software that enables the users to define, create, maintain and control the access to the database. It is a software that interact with the user’s applications programs and it database. Meanwhile, information retrieval system is a system that involved the activity that the systems obtain the information. The obtaining information action need the information from it resources.
Project management involves all activities that encompass scheduling, planning, and controlling projects. A successful project manager ensure that an organization’s resources are being used both efficiently and effectively. Most projects need to be uniquely developed require a sense of customization and the ability to adapt to any posed challenges. The scope of effective project management includes defining what the project is and what is being expected to be accomplished. Projects are imposed to fulfill a certain need and project managers must have the ability to create the proper definition. Goals and the means used to attain those goals have to be clearly stated. Project Managers must also have the ability to plan
