Resource Allocation Protocol
charter-ietf-rap-01

Recent work in the IETF have led to the development and
standardization of enhanced network services such as QoS and traffic
engineering. The complexity of these services and the variations in
the capabilities of the devices implementing these services provide a
challenge to anyone trying to configure services within medium- and
large-scale networks.

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.

• 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.
