The document outlines the testing and implementation process for a network upgrade at IIS. An initial network test during off-hours will be followed by a final test during normal business hours to fully evaluate performance. Testing will validate goals, technology selections, and service levels while analyzing redundancy, performance, and risks. Users and administrators will be notified in advance of any tests. Installation will involve laying fiber optic cable between branch offices. The designed network aims to ensure security, speed, reliability and scalability. A schedule is provided detailing preparation, planning, design, and implementation over 50 days.

- 1. Solutions Details After all details are finalized and upgrade design strategy complete, the implementation of the network upgrade will transpire with minimal or no downtime within IIS. As part of our implementation plan, an initial network test will occur. This will be done during off-hours to minimize possible problems; however, the final test will be done during normal business hours to completely evaluate the network upgrade performance. The following items below will be completely under evaluation: Verify the designupgrade meets key business and technical goals. Validate LAN and WAN technology and device selections. Verify the service provider provides the agreed-upon service. Testing before Installation Test the redundancy of the network. Analyze the effects on performance during network link failures. Determine the optimization techniques to meet performance and other technical goals. Analyze the effects on performance while the upgrade of network links or devices is under construction ("what-if analyses"). Identify any risks that can impede implementation and determine the plans for contingencies. The following are considerations to experience while a "live" test is under implementation: Warn users in advance about the timing of tests so they can expect some performance degradation, but ask the users to work as they typically do to avoid invalidating the test by abnormal behavior. Moreover, have the users report any issues that arise during the live test. Warn network administrators and other designers in advance to avoid the possibility that they could be running tests at the same time. Warn network managers in advance, so they are not confused by unexpected alarms on network- management consoles, and so they can account for test traffic when documenting load and availability statistics. If possible, we will run multiple, short (less than 2-minute) tests to minimize user impact and lessen the effects on baseline measurements.
- 2. Monitor test results and discontinue them when test objectives are met, or the production network is severely impacted or fails. Furthermore, we will provide a follow-up after implementation. We will follow up every day until all issues have been resolved and the design/upgrade has been fully completed Identify any bottlenecks or connectivity problems Installation Details IIS WAN will contain connections between each branch office and the headquarters. Fiber optic cable will be laid between each office. Cabling distances were determined using the distances between cities. IIS will lay their own cable, Network Documentation Details The network is designed to meet the following requirements: Security. The network has been designed to prevent unauthorized access, both logically and physically. Speed. The network has enough bandwidth to meet demand during periods of peak usage. Reliability. The network has redundancy to ensure that the failure of one system will not bring the entire network down. Scalability. The network is capable of sustaining scalability without the need to rebuild the entire network. Changes and updates must be easy to implement. Schedule 1.
