Summary

Recommendation ITU-T Y.2022 describes the functional architecture for the support of host-based of ID/locator separation in NGN. ID/locator separation in NGN is concerned with decoupling the semantics of IP addresses into the semantics of identifiers (node IDs) and locators (LOCs) as described in Recommendation ITU‑T Y.2015.

This Recommendation defines the functional entities and the related reference points, based on the framework architecture provided in Recommendation ITU-T Y.2012.

This Recommendation covers only the host-based case of ID/locator separation (the separation of node ID and locator is done in the User Equipment and not in the network).
