Method for establishing logical connections in a synchronous digital data communication network , network element and management system

Abstract

In a method for establishing logical connections in a synchronous digital communications network (SDH), the several, at least partially interconnected network elements (NE1, NEn; CC1-CC3) and is provided for transmitting data packets with a destination address, the destination addresses of the data packets to be transmitted are monitored, Based on the destination addresses, the traffic volume between the individual network elements (NE1, NEn; CC1-CC3) and an optimized configuration of logical connections is determined on the basis of the traffic volume and already existing logical connections. As a result, the communication network is adapted to the current traffic situation, and the transmission capacity of the network are used as best as possible. The monitoring advantageously takes place in at least part of the network elements, while the determination of the traffic volume and the optimized configuration is carried out by a central management system (TMN).
