Summary - M.3375 (03/2026) - Framework for management of cross-domain network slices in IMT-2020 networks and beyond

Recommendation ITU-T M.3375 specifies a framework for the management of cross-domain network slices in IMT-2020 network and beyond to efficiently implement management and coordination of cross-domain network slices, including cross-domain network slices interworking.
Network slicing has emerged as a crucial feature and enabler for the IMT-2020 networks. The increasing demand for network slices renders cross-domain network slice interworking a challenging task. Therefore, it is highly imperative to ensure coordination among the three network slice subnet management systems for the access network, transport network and core network.
