1 Motivation
Demands for ever increasing transport networking functionality and responsiveness to its range of users' needs continue to rise. This has triggered both evolution, and introduction of new, control and management paradigms (e.g., application of software defined networking (SDN), artificial intelligence/machine learning (AI/ML), virtual network (VN), security, digital-twin, use of open source tools to create, validate and translate information models, and quantum information technology), with a corresponding increase in variety of control/management interface protocol solutions that may be deployed in transport networks. Transport networks may be vast and complex (e.g., multi-technology/layer, multi-protocol, multi-vendor) and co-existence among control and management paradigms is essential to enable large scale operational integration. Given the underlying transport resources remain the same, independent of the paradigm(s) employed, it is increasingly essential to provide a coherent information model of transport resources to enable interoperability between the different management/control paradigms and solution data models. Such factors will drive the need for the revision of existing Recommendations as well as the development of new Recommendations relevant to the control and management of transport network resources.
Building upon the foundation architectures of transport data plane, including media, and control-management (e.g., automatically switched optical networks (ASON) and SDN) of Q12/15 (transport network architectures), Q10/15 (packet-based transport), Q11/15 (optical transport), and Q13/15 (synchronization), this Question is responsible to develop the specifications for the control and management of transport network resources, encompassing requirements, protocol-neutral Information Models (IM) and protocol-specific Data Model (DM) solutions for common transport functionality and transport technology-specific functionality (e.g., metro transport network (MTN), optical transport network (OTN), Ethernet transport, MPLS-TP, and media). To ensure coherent specifications and interoperability among the protocol-specific solutions, this Question is also responsible to develop guidelines for deriving protocol-specific solution DMs through pruning and refactoring of the protocol-neutral IMs to ensure coherent DM specifications and their traceability to the protocol-neutral IM. This Question is also responsible to develop the specifications of the architecture and requirements for the data communications network (DCN) encompassing control and management paradigms. These activities will be conducted in close co-operation with related ITU-T Study Groups, TM Forum, IEEE, IETF, MEF Forum, Broadband Forum, and other SDOs or Industry alliances as necessary.
