9. Acknowledgments
Early versions of this specification were also co-authored by Michael Fine, John Seligson, Carol Bell, Andrew Smith, and Francis Reichmeyer. This PIB builds on all the work that has gone into the Informal Management Model for DiffServ Routers and Management Information Base for the Differentiated Services Architecture. It has been developed with the active involvement of many people, but most notably Diana Rawlins, Martin Bokaemper, Walter Weiss, and Bert Wijnen.10. Security Considerations
The information contained in a PIB when transported by the COPS protocol [COPS-PR] may be sensitive, and its function of provisioning a PEP requires that only authorized communication take place. In this PIB, there are no PRCs which are sensitive in their own right, such as passwords or monetary amounts. But there are a number of PRCs in this PIB that may contain information that may be sensitive from a business perspective, in that they may represent a customer's service contract or the filters that the service provider chooses to apply to a customer's traffic. These PRCs have a PIB- ACCESS clause of install:
dsDataPathTable, dsClfrTable, dsClfrElementTable, dsMeterTable, dsTBParamTable, dsActionTable, dsDscpMarkActTable, dsAlgDropTable, dsMQAlgDropTable, dsRandomDropTable, dsQTable, dsSchedulerTable, dsMinRateTable, dsMaxRateTable Malicious altering of the above PRCs may affect the DiffServ behavior of the device being provisioned. Malicious access of the above PRCs exposes policy information concerning how the device is provisioned. This PIB also contain PRCs with PIB-ACCESS clause of notify: dsBaseIfCapsTAble, dsIfClassificationCapsTable, dsIfMeteringCapsTable, dsIfAlgDropCapsTable, dsIfQueueCapsTable, dsIfSchedulerCapsTable, dsIfMaxRateCapsTable, dsIfElmDepthCapsTable, dsIfElmLinkCapsTable Malicious access of the above PRCs exposes information concerning the device being provisioned. The use of IPSEC between PDP and PEP, as described in [COPS], provides the necessary protection.11. Intellectual Property Considerations
The IETF has been notified of intellectual property rights claimed in regard to some or all of the specification contained in this document. For more information consult the online list of claimed rights.12. IANA Considerations
This document describes the dsPolicyPib Policy Information Base (PIB) modules for standardization under the "pib" branch registered with IANA. The IANA has assigned a PIB number (4) under the "pib" branch. [SPPI] PIB SUBJECT-CATEGORIES are mapped to COPS Client Types. IANA Considerations for SUBJECT-CATEGORIES follow the same requirements as specified in [COPS] IANA Considerations for COPS Client Types. The DiffServ QoS PIB defines a new COPS Client Type in the Standards space. The IANA has assigned a COPS client type diffServ (2) as described in [COPS] IANA Considerations. IANA has updated the registry (http://www.iana.org/assignments/cops-parameters) for COPS Client Types as a result.
