Summary of Traffic Analysis:
1- Generally at Campuses A, B, and D, the network is composed of a switched backbone architecture, in which traffic from all classrooms is fed into a central switch. At Campus-C, however, combined traffic from neighboring classrooms and staff office wings is fed into two central switches.
2- LAN Performance: The LAN Segment Utilization Table below presents the bandwidth utilization of the different segments of the network at Campus-C. However, this could be applied to all other locations.
Requirements, Issues, Constraints
Business Requirements:
1- As per directive from the senior team, all Campuses and Dorm would be WiFi friendly as well as all Campuses and their lab areas would be printer friendly- i.e. one can request printout from ANY station ANYWHERE and be able to get it from ANY printer ANYWHERE.
2- Provide at least three WiFi Hot Points at each Campus to suit the building layout and the appropriate access for users grouped as “management & staff”, “students” and “guests”.
3- Plans to implement “Voice over IP” phone sets to the desktop, but the vender or technology has not being selected- you are free to recommend in your report.
Technical Requirements:
1- Apply a hierarchical approach to design this network. Your network design diagram should show:
a. i. Core Layer
b. ii. Distribution Layer
c. iii. Access Layer
2- Improve system Bandwidth for the users to accommodate for growth (assume 5% per year) at all Campuses.
3- Plan for Internet availability improvement
4- Required Public IP addresses for the College
5- Upgrade several of the server hardware platforms (to provide performance and fault tolerance) as seen necessary at any Campus(es).
6- Implement an Internet firewall (to provide security) wherever is deemed necessary.
7- Provide a more robust uninterruptible power supply (UPS) system (to provide fault tolerance and availability) for key infrastructure equipment and servers.
8- Provide secure remote login connections for 50 staff, who are mobile and work remotely from outside their offices. Make a suitable choice of technologies in this case. This number will double to over the next two years.
