TR291H Intent Guarantee – Intent Extension Model v3.6.0

The Intent Guarantee model extends the vocabulary of the TM Forum Intent Ontology (TIO) to support the request for guarantees that are future looking and that are statements of enduring compliance. Supporting guarantees implies that an intent handler shall be capable of predicting future outcomes and ensuring requirements with agreed confidence/probability, throughout an agreed guarantee period, by utilizing methods such as statistical prediction modeling, digital twin simulations, isolation and partitioning of resources, redundant resources, prioritization and so on. The confidence by which the intent handler is expected to issue guarantees is specified as a confidence/probability level by the intent owner and defines the number of outcomes of a requirement that must be positive over time. The exact handling of this is implementation specific, but generally the method used for prediction shall be verifiable using the methods provided by a system for collecting and presenting metrics for instance. Guarantees are also subject to validity expressions, which allows the intent owner to define conditions for when guarantees shall be employed, such as restricting guarantees to certain times, applying different guarantees at different times or requesting guarantees if some other condition is true for instance.
