Network Design Exercise
Design Project -
Objective - The task is to develop a network for a multi site company.
This exercise attempts to give experience of a real world design that you may be asked to do in your future employment. As a result, only minimal guidance is given. You will need to fall back on all the experience that you have gained from the previous exercises. You will be assessed based on the decisions you made in each stage of the project.
Overview
The network to be designed connects computers across three sites. The main site, called "Base" has four floors connected via a fast backbone network. One external site is connected using FDDI, and the other uses a T3 link through the Internet (protected with a firewall).
The network should be analyzed and improvements recommended. An option to relocate some of the servers can be considered. The backbone network upgrade from serial to partially meshed should also be evaluated.
Tasks -
- Requirements analysis - create a detailed design requirement specification
- Project Planning - evaluate required tasks, plan task execution sequence and estimate individual task duration.
- Applications and profiles modeling - identify scenarios needed to complete the project.
- create a hierarchical network in Riverbed Modeler
- simulate scenarios
- modify the network to validate potential improvements
- create a project report
Assessment -
This is an individual project. You will be assessed as follows:
- Initial network planning (show your work)
- network topology
- network address spaces planning
- applications modeling methods (show your work)
- profiles modeling
- simulation and results
- report
For a successful assessment:
- ensure all included screen clips are readable
- every image has a reason to be included, and a description (not just a name)
- include screen clips showing each application and profile configuration detail
- include the DES Log, and a description of warnings and errors listed
- include traffic plots for individual applications/profiles that show how accurate the model is.
