MCI Private Network Model Design: Digital DS-3 Cross Connects

June 5th, 2009

Client: MCI Communications Corp.
Team:  Mona Abou-Sayed, Charlene Edwards, Scott Singleton
Faculty advisor: Dr. Richard Barr     Year: 1995
Documents:   Final report

This project involved developing an optimized  telecommunications-network design for a client of MCI Communications Corp. Requirements included determining the optimum number of nodes, their placement, and Digital Signal 3 (DS-3) lines need ed to connect all the cities and meet their demands while providing restoration capacity in the case of system component failures.

Several heuristics were used to find the initial placement of nodes and begin a cost minimization analysis. A mixed-integer programming model was developed and solved with Cplex, followed by manual adjustments to the node location assignments and network links. The optimal cost was found to be: $4,461,868, which could be improved with further development.
