Summary

As one hierarchical packet data network which can meet requirements of future packet based networks, the public packet telecommunication data network (PTDN) has a reference point, called the M interface, between the PTDN management entities and network elements. Recommendation ITU‑T Y.2618 defines this interface, specifies common PTDN management functions and protocols and defines specific PTDN management functions related to a virtual packet network (VPN) and multicast service. Annex A of Recommendation ITU‑T Y.2618 describes a management information model for VPN and multicast service management using the management interface specification methodology defined in Recommendation ITU-T M.3020.
