Network dimensioning for a multi-service integrated digital network with dynamic routing

With ISDN user part (ISUP) signalling, it will be possible to provide different services in the same transmission facility without dedicated partitioning. The paper considers a multi-service switched integrated digital network with dynamic routing where several services are offered. This type of network provides a viable platform for deploying new services in the ISDN era by taking advantage of the dynamic routing capabilities. The paper addresses the problem of network dimensioning for such a multi-service dynamic routing network and presents mathematical formulations of this problem. Exploiting the structure, it proposes a penalty-function based decomposition algorithm for solving this problem
