Vodafone have read the draft RFC and fully support it. We have been extensively engaged in testing LLD (Low Latency DOCSIS) & L4S technology implementations and so we are familiar with the benefits of NQB & dual-queue approaches to scheduling. As a consequence of our testing, we are fully convinced of the benefits of this approach.

All best,
Kevin

I strongly support this document. We at Comcast have tested NQB PHB via field trials in our network and it is working as expected. We have succeeded in getting this to work across domain boundaries with peer networks. It is also working inside customer premise equipment (CPE) - per document section 7.1 (DOCSIS Access Networks) on a trial basis and we expect to begin production deployment of this feature in CPE very soon. In cases where WiFi is integrated into a Comcast-administered CPE, we have also deployed WiFi support per document section 7.3.1 (Interoperability with Existing Wi-Fi Networks).

During our trial we have detected no negative performance effects or stability issues.

Jason
