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.
