Problem Description

THE NETWORK DESIGN PROBLEM

Adapted from a real world problem

Before undertaking this case study you must (at least) read the DataNetworkFlows case study to learn about the components that make up Storage Area Networks (SANs).

The company that commissioned the initial research on routing their data (see DataNetworkFlows) has decided to add another storage device (Device C) to their network. They have also performed some extensive data traffic measurement and determined the actual data flow requirements they need to support. These flows are shown in Table 1.

Source Destination Requirement Mb/s
Host 1 Device A 65
Host 1 Device B 50
Host 1 Device C 30
Host 2 Device A 25
Host 2 Device B 70
Host 3 Device A 35
Host 3 Device C 65

They estimate they will need either an extra hub or an extra switch or some combination of the 3 hubs and 2 switches. They commissioned the same network consultant to design their new network for them. He finished the job, but left for his honeymoon before writing a management summary or documenting his work. The files he left are contained in:

??? LINK ??? san_design.zip

The company want to use these files to find the optimal SAN design that will support their data flow requirements.

1. Comment the AMPL files san_design_neos.mod, san_design.dat and san_design_neos.run from san_design.zip. Run these files to find the optimal SAN design to support the flow requirements. Write a management summary for your solution.
