Service Graphs Generation in Intent-Based Networks

Intent-Based Networking (IBN) has recently gained interest to realize intelligent cloud management systems. IBN makes cloud consumption user-friendly by allowing users to specify "what needs to be done" rather than "how it should be done". In this paper, we address the problem of service graphs generation in IBN, while considering functional requirements derived from user intent. We propose a solution that uses a domain ontology to translate the intents into their functional requirements which are specified in terms of initial services. Then, we use a service catalog along with the initial services to generate all possible service graphs that can meet the functional requirements of the given intent. Our evaluations show that the proposed solution achieves up to 84% improvement of the execution time compared to the existing benchmarks.
