Abstract:

In the future, network will necessitate flexible, resilient, and scalable frameworks to accommodate evolving and diverse services. Intent-driven network provides a practical and feasible new idea for addressing this challenge. Specifically, intent-driven loop allows network administrators to focus less on intricate configuration details and more on expressing service requirements, facilitating autonomous and reliable services. Firstly, this work analyzes new challenges emerging in the field of cybersecurity. Subsequently, it introduces the methodology and key technologies of intent-driven network, proposing a lifecycle intent-driven architecture based on intent-driven network. Secondly, a method of reasoning for resilience strategies is introduced in intent-driven network security services. The practical application of intent-driven network involves the generation, translation, policy formulation, and deployment of intents, thereby ensuring the continuous online availability of network services even in the event of network failures. This reflects the entire lifecycle of an intent-driven network.

Key words: intent-driven network, network security, network policy, network resilience
