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.
