[Ideas] WG Review: IDentity Enabled Networks (ideas)

[The IESG <[e-mail]>]

A new IETF WG has been proposed in the Routing Area. The IESG has not made
any determination yet. The following draft charter was submitted, and is
provided for informational purposes only. Please send your comments to the
IESG mailing list ([e-mail]) by 2017-10-09.

Charter: https://datatracker.ietf.org/doc/charter-ietf-ideas/

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.  We refer to the framework providing the set of services as
Generic Identity Services (GRIDS).

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 define privacy requirements and how potential
extensions/solutions should meet them.

- 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) Generic Identity Services Framework

(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.
