The IESG has approved the following document: - 'Diameter Congestion and Filter Attributes' (draft-ietf-dime-congestion-flow-attributes-02.txt) as Proposed Standard This document is the product of the Diameter Maintenance and Extensions Working Group. The IESG contact persons are Benoit Claise, Kathleen Moriarty and Joel Jaeggli. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-dime-congestion-flow-attributes/ Technical Summary This document defines optional Explicit Congestion Notification (ECN) and filter related attributes that can be used for improved traffic identification, support of ECN and minimized filter administration within Diameter. RFC 5777 (Traffic Classification and QoS Attributes for Diameter) defines a Filter-Rule AVP that accommodates extensions for classification, conditions and actions. In this draft, the Classifier Grouped AVP contained in the Filter-Rule AVP is extended with the new ECN-IP-Codepoint AVP which gives the Explicit Congestion Notification (ECN) codepoint values (defined in RFC3168) to match in the IP header. Moreover, the Filter-Rule Grouped AVP itself is extended with a new Congestion-Treatment AVP that indicates how congested traffic should be treated. The Flow-Count and Packet-Count AVPs are also defined in this document to be sent to report in application specific command information of the group of flows described by the Filter-Rule, IPFilterRule or other Diameter traffic filters. This information can be used by the application for improved decision making, Charging and rudimentary traffic profiling. Working Group Summary The working group has consensus supporting this draft. Document Quality No additional reviews are requested. Personnel The document shepherd is Lionel Morand. The responsible Area Director is Kathleen Moriarty. IANA Note This daft provides the specification required to add IANA allocated AVP codes in the IANA-controlled namespace registry specified in Section 11.1.1 of [RFC6733] for the AVPs defined in this document.
