The working group will define general-purpose objects that facilitate the manipulation of policies and provisioned objects available through COPS and COPS-PR. Where appropriate, these will include frameworks clarifying the applicability of COPS objects and the best practices for the definition of additional objects defined in other working groups.
In particular, the group will address the following work items:
- A standards track framework document describing the usage of COPS in carrying usage reporting and unsolicited state change information between a PDP and a PEP [FEEDBACKFRWK].
- A standards track document describing a feedback PIB to be used to carry usage/feedback information from the PEP to the PDP [FEEDBACKPIB].
- Complete work on the standards track documents for (a) the data definition language for COPS-PR [SPPI] and (b) the set of core data definitions for QoS provisioning [FRWKPIB].
- A standards track document describing a modular architecture for a COPS based Management Framework. The document will address the COPS message processing, security and access control and may specify examples of how the framework may be implemented. [COPSFRWK]
- A standards track document describing a framework or PIB to enable the explicit binding of QoS to to authenticated agents, such as corporate entities or individual users. The purpose of this document is to define a set of data structures that represent subscriber identity, subscriber credentials, and provide support for proxing various authentication strategies. This document will describe the client-server interactions necessary to install identities, bind identities to other provisioning components and the credentials necessary to complete authentication. Identities may be represented in the data structures defined by this document and may take one of many forms. Examples include none (open) partial (snooped by the network device), and full (provided by an existing authentication protocol). Examples of existing protocols include 802.1x, PAP, CHAP, EAP, Kerberos, HTTP, TLS, SSL, and SRP. [BINDFRWK].
- An informational document describing the use of COPS over TLS. [COPSTLS]
The working group will continue to document changes to COPS objects needed to support any extensions to RSVP and extensions to RVSP directly related to usage control. Specifically the working group will pursue:
- A version of draft-ietf-rap-rsvp-newidentity that addresses security shortcomings with the current document [NEWIDENTITY].
- A standards track document defining new ErrorValues for the RSVP Policy Error Object [RSVPERRVAL].
- A standards track document defining the framework and mechanism for authorizing of RSVP sessions [SESSIONAUTH].
- A standards track document defining an RSVP Local Policy Control Criteria PIB [RSVPPIB].
Documents produced by the working group must fully address all the security aspects of this type of protocol. In particular, theft and denial of service threats must be minimized.
The Working Group will not define semantics of objects for any specific protocol or technology. Such work will be done (if done at all) in protocol or technology specific WGs.
For the work on the [FEEDBACKFWRK] and [FEEDBACKPIB], the WG will work with other WGs (like AAA WG) to prevent duplication and overlapping solutions.
