Summary:
|
In recent years, new network technologies and services have been emerging continuously. Network load has kept increasing, network scale has expanded steadily, and network complexity has been rising day by day. These changes have brought unprecedented challenges to network operation and maintenance support, operational efficiency, and business innovation. The traditional device-centric and passive-responsive network operation and maintenance model can no longer meet the needs of current network development. Once a network failure occurs, it may lead to high costs.
A digital twin network (DTN) is a virtual representation of a physical network [ITU-T Y.3090]. It is useful for analysing, diagnosing, emulating, and controlling the physical network based on data, model, and interface, to achieve a real-time interactive mapping between physical networks and digital twin networks.
In ITU-T, [ITU-T Y.3090] has defined the functional architecture of digital twin network. It is time to initiate the study on the signalling architecture of digital twin network. This proposed new draft recommendation focuses on the signalling architecture aspect and will be developed based on the requirements and functional architecture which are specified by [ITU-T Y.3090].
