Dynamic tunneling peering with performance optimization

The present invention provides a method of connecting between a plurality of network nodes (TP0 to TP5) is used, wherein each network node is connected via virtual direct connections, the method comprising the steps of: a virtual network between each pair of nodes directly quality measurement (S4) is connected; and based on the results of the quality measurements, it is determined whether the virtual direct connection is to be used to transmit data (S7 to SlO); wherein the results of the quality measurement is transmitted to this determination step network configuration control unit . The invention also proposes a corresponding network system.
