RRX Network AAA
In optical networks the efficient routing of optical connections
is critical.
As today the optical
networks are composed of multiple provider administered domains, there
might be a long term future requirement for dynamic interdomain optical
circuit provisioning.
Whether this
provisioning is initially driven from the core, edge, or end node requests
a minimal set of interdomain protocol capabilities are implied.
To effectively
determine reasonable interdomain optical paths there must be a set of
information that can be shared, between domains.
Recent research by RRX Network indicates a reasonable preliminary goal is to identify
a minimal set of this information and potential mechanisms for its collection, and to
propose novel solutions for interdomain routing.
An AAA
or AAAA service is involved in handling three basic decisions.
The first
task is the verification of identities (Authentication). Secondly
it determines if conditions are met for the usage of resources (Authorization).
Finally the service may log key attributes of its decisions so they can
be used later, for Accounting purposes. Notably the basic AAA service might
also be promoted by some form of (Advertising), implying AAAA.
