The IESG has approved the following document: - 'A PIE-Based AQM for DOCSIS Cable Modems' (draft-ietf-aqm-docsis-pie-02.txt) as Informational RFC This document is the product of the Active Queue Management and Packet Scheduling Working Group. The IESG contact persons are Spencer Dawkins and Martin Stiemerling. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-aqm-docsis-pie/ Technical Summary Cable modems based on the DOCSIS(R) specification provide broadband Internet access to over one hundred million users worldwide. In some cases, the cable modem connection is the bottleneck (lowest speed) link between the customer and the Internet. As a result, the impact of buffering and bufferbloat in the cable modem can have a significant effect on user experience. The CableLabs DOCSIS 3.1 specification introduces requirements for cable modems to support an Active Queue Management (AQM) algorithm that is intended to alleviate the impact that buffering has on latency sensitive traffic, while preserving bulk throughput performance. In addition, the CableLabs DOCSIS 3.0 specifications have also been amended to contain similar requirements. This document describes the requirements on Active Queue Management that apply to DOCSIS equipment, including a description of the "DOCSIS-PIE" algorithm that is required on DOCSIS 3.1 cable modems. Working Group Summary There were no extraordinary events in the WG process on this document. Document Quality The document quality is high. Implementations would likely be done from the DOCSIS spec itself rather than this document, which is really just tying together the IETF AQM work with what has been completed earlier in the DOCSIS specifications. Personnel Wesley Eddy (wes@mti-systems.com) is the shepherd and Martin Stiemerling (mls.ietf@gmail.com) is the AD.
