Network solutions based on the concept of Identifier-Locator separation
are increasingly considered to support mobility, overlay networking for
virtualization and multi-homing across heterogeneous access networks.
Identifier-locator separation protocols require infrastructure that allows
nodes to discover the network topological location(s) of its peer(s) for packet
delivery. A common infrastructure and protocol could be used by
identifier/locator protocols as well as network virtualization. However,
additional infrastructure and new protocol extensions are needed to address new
requirements that go well beyond the traditional discovery service and mapping
of identifier-to-location for packet delivery. Identifier-locator protocols are
also useful for additional services involving dynamic association of a name to
a set of network addresses - these include dynamic multicast, cloud service
anycast and context-aware IoT queries.

The IDEAS WG is chartered to produce a framework document that defines the
expected behavior of a mapping system across the multiple existing use cases. 
The framework will aim at a homogeneous behavior across use cases, and it will
call out specific trade-offs that may be considered in the development of
solutions.

Some of the areas that must be considered when developing the framework include:

- Description of interfaces for different protocols to interact with the
framework (e.g. id-loc split protocols, management protocols, etc)

- Description of identifier/locator mapping resolution and mapping update (e.g.
discovery, pub/sub, multi-homing, ...)

- Registration and lifecycle management of identities and their associated
identifiers.

- Identity authentication and authorization (e.g. access to framework, update
of information for identifiers..)

- Description of required basic network policies and policy enforcement needs
(e.g. ability to look up an identifier-locator pair, permit forwarding traffic
for particular endpoints on a per-identity basis, etc.)

- Analysis of the concepts of identity-identifier split and dynamic identifier
changes, including their implications on anonymity and privacy. Explicitly, the
framework must clearly identify any threat to privacy and anonymity and
mechanisms to be used in their mitigation.

- Security analysis of the complete system, including authentication,
authorization requirements and protection of any metadata.

- Operational and deployment considerations

The IDEAS WG will closely coordinate with the LISP and HIP WGs (and with others
as needed) in order to keep them well-informed of the progress.  Any extension
to existing protocols that is identified while developing the framework
document will be carried out in the responsible WG for that protocol; any
extension work to be done in this WG will require re-chartering.

WG deliverables include:

(1) Framework document

(2) Other WG sustaining/informational documents may include:

- Problem statement
- Use cases
- Requirements for identifier/locator mapping and resolution
- Requirements for identity authentication and authorization service (for GRIDS)
- Applications of the architecture for use cases
- Threat model document

These documents will not be published as RFCs, but will be maintained in a
draft form or on a collaborative Working Group wiki to support the efforts of
the Working Group and help new comers. Nonetheless, it is expected that the
Working Group will actively discuss the content of any support document and
reach consensus on them.
