[Ideas] IDEAS Charter

[Padma Pillay-Esnault <[e-mail]>]

Dear IDEAS

The final outcome of the discussions on the alias is reflected in the text
below. This version is based on the edits done by Alvaro, some of the
latest comments and fixing some nits.

Thank you all for your feedback and comments.

Looking forward to the next milestone

IDEAS: “IDentity EnAbled networkS”



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 should be considered when developing the framework
include:



- Flexibility and extensibility considerations



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



- Requirements for 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…)



- Analysis of the concepts of identity-identifier split and dynamic
identifier changes, including their implications on anonymity and privacy.





The IDEAS WG will closely collaborate with LISP and HIP WGs. The WG will
also collaborate with other WG as needed.



WG deliverables include:



(1) Generic Identity Services Framework



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



These documents may not necessarily be published, but may 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:



- 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
