AN ALGORITHM FOR CONFIGURING EMBEDDED NETWORKS IN RECONFIGURABLE TELECOMMUNICATION NETWORKS

This paper considers a problem of configuring logical networks by empl oying a self-planning facility in a telecommunication network carrying voice-grade calls to make the least-cost configuration where the invo lved system cost includes hop cost and lost-call traffic cost. The hop cost depends on the number of self-planning facilities included on ro uting path connecting the associated node pairs, while the lost-call t raffic cost is incurred due to link capacities. The configuration prob lem is analyzed through dimensioning and routing on a reconfigurable n etwork in a mixed 0/1 nonlinear programming approach for which lower b ounds are found by Lagrangian relaxation embedded in a hybrid search p rocedure for the associated dual problem. Heuristic solution procedure s are exploited and their efficiencies are tested with various numeric al examples.
