Summary:
|
In order to adapt ever-changing business requirements, intent-based network(IBN) has emerged. The IBN can express in simple terms, what the network wants to accomplish in a natural language; the network can then convert the intent into specific policies and automatically complete cross-domain and cross-network configurations in complex and heterogeneous environments according to the corresponding policies. Thus, the business purpose of the application layer is achieved, avoiding time-consuming and labour-intensive manually performing tasks.
ITU-T have already been involved IBN standardization work. For example, there are some work related to IBN concept adopted for network evolution, SG13 Q2 has specified the scenarios and requirements of Intent-Based Network for network evolution in Y.2344(formly Y.IBN-reqts), and studied functional architecture of NGN evolution by adoption of Intent-Based Network in Y.NGNe-IBN-arch. Correspondingly, SG11 Q1 has initiated the work item Q.IBN-SA which provides specification about the signalling architecture of Intent-Based Network for network evolution. SG2 Q6 has initiated the work item M.fidtom which provides framework of intent driven telecom operation and management. In addition to IBN for network evolution, SG13 Q21 has adopted IBN concept for network slicing in Y.3161(ex. IMT2020-IBNMO), which describes the intent-based network management and orchestration for network slicing in IMT-2020 networks and beyond. In fact, to achieve intent-based management and orchestration of network slicing for better perceive network slice customer’ intents and reducing operation and maintenance expenses, it’s necessary to address the signalling and protocol aspects on how the intent operation drives lifecycle management of the network slice.
SG13 has finished the standardization work on requirements and architecture of intent-based network management and orchestration for network slicing in IMT-2020 networks and beyond, so it’s time to continue the standardization work of signalling and protocol for intent-based management and orchestration of network slicing in IMT-2020 networks and beyond, to accelerate the application of intent-based management and orchestration of network slicing. So it is proposed to initiate a new work item to specify signaling and protocol for intent-based management and orchestration of network slicing in IMT-2020 networks and beyond.
