Summary: For future network evolution, there exists a stream that proposes to decouple the traditional IP address into node identifier and routing locator, which is also known as Identifier/Locator Split (ILS) paradigm for future networks [ITU-T Y.2057]. However, in reality, there co-exist multiple ILS schemes such as LISP [RFC6830], HIP [RFC7401], ILNP [RFC6740], and so forth. All these ILS schemes share a similar abstract concept but with distinct design details and application scenarios. Recently, some of ILS schemes are proposed and tailored for IoT applications, such as HIP for IoT security enhancement, LISP for IoT mobility, etc., while the non-IP protocols may take the IP-based payload in ILS paradigm as payload at data link layer frames for extended and value-added functions. Also, the role of Identity with explicit binding with Identifiers could be of interests for IoT as well, which can provide many enhanced functions. In addition, IoT enabling technologies are highly diversified nowadays, which might be regarded as IP and non-IP solutions in general. The recommendation [ITU-T Y.3034] provides architecture for interworking of heterogeneous component networks in ID/locator split-based future network, there still is lack of new methods to enable all ILS-based interworking, under a unified identity/identifier split and identifier/locator split architecture. As a result, the intent of this proposed new draft recommendation is to provide a unified identity/identifier split and identifier/locator split architecture for future networks, with a dedicated focus on diverse IoT interconnections and applications. For which a set of basic and value-added services, with some necessary interfaces, will be studied. Specifically, the following main contents will be presented for filing the gaps of existing technologies: - Define identifier and locator split for non-IP technologies - Develop interworking mechanisms between IP and non-IP technologies - Develop UIIS a common service mechanism which enable interoperability under a unified IIS and ILS paradigm ? - Identity/Identifier-based services, especially for their customized services in different IoT applications. This work may rely on the following basic services and technologies which are expected to be developed by other SDOs, in particular the IETF IDEAS working group when it has been created: - Identity service - Mapping service
