Network architecture for communication networks or data networks

A network architecture of telecommunications networks having distributed physical resources providing data and telecommunications services associated with individual users that are processed and used independently in each telecommunications network, comprising:

• at least one group of subnetwork elements for each telecommunications network, forming at least one subjacent physical network in each telecommunications network and providing network functions and network services of the telecommunications network to at least one user independently of other telecommunications networks;
• and
• linked network elements, forming a layer connecting the subjacent physical networks, including system-independent interfaces using a uniform logical interface to make available the network functions of different subjacent physical networks to the at least one user and to provide function invocations for function classes, which can be converted into at least one of subjacent physical network-specific messages and commands and forwarded to suitable network elements of the different subjacent physical networks, and can be processed or carried out there.
