I am not a wireless expert, but my guess is that it would be even >more difficult to accurately track usage on wireless given the portable >nature. Since my day job is at Comcast and part of that job is ensuring that the usage meter is technically accurate I figured I would chime in. A few bits of information that may be helpful follow below. **I am happy to answer any questions you or others have.** And I have also copied our independent auditor should there be questions for his firm. 1 - Comcast does byte counting via the IPDR standard (IP Detail Records). I would think any other DOCSIS-based network that performs byte counting would also use IPDR (and all the ones of which I am aware do so). You can find some more information about the IPDR specification here: https://en.wikipedia.org/wiki/Internet_Protocol_Detail_Record https://www.incognito.com/tips-and-tutorials/faq-bandwidth-monitoring-with- ipdr/ http://www.dslreports.com/r0/download/1603814~d44a19780841cdc79abf840b6066d 52d/ipdr-usage-counters.pdf http://www.cablelabs.com/wp-content/uploads/specdocs/CM-SP-OSSIv3.0-I14-110 210.pdf 2 - Comcast first made mention of the use of IPDR in a 2008 FCC filing, as part of a deployment of a protocol-agnostic congestion management system. See these documents: http://downloads.comcast.net/docs/Attachment_B_Future_Practices.pdf https://tools.ietf.org/html/rfc6057 3 - Comcast engaged a 3rd party auditor called NetForecast (http://www.netforecast.com/) to regularly, independently audit the accuracy of our usage meter. We usually announce those audits on our Network Management page (ex: http://networkmanagement.xfinity.com/index.php/8-network-management-news/55 -2015-comcast-usage-meter-accuracy-report) and NetForecast publishes these reports on their website. See the following documents: - First accuracy report, 2009: http://www.netforecast.com/wp-content/uploads/2012/06/NFR5101_Comcast_Usage _Meter_Accuracy_Original.pdf - Second accuracy report, 2010: http://www.netforecast.com/wp-content/uploads/2012/06/NFR5101_Comcast_Usage _Meter_Accuracy.pdf - Third accuracy report, 2014: http://www.netforecast.com/wp-content/uploads/2014/05/NFR5116_Comcast_Meter _Accuracy_Report.pdf - Fourth accuracy report, 2015: http://www.netforecast.com/wp-content/uploads/2015/06/NFR5120_Fourth_Comcas t_Meter_Accuracy_Validation_Report.pdf - ISP best practice report: http://www.netforecast.com/wp-content/uploads/2015/06/NFR5119_General_ISP_D ata_Usage_Meter_Specification.pdf 4 - In terms of what is counted, all Internet traffic is counted (what is now known as Title-II traffic). Title-VI video traffic and Xfinity Voice traffic, which may use the IP protocol but are not Internet services, are not counted. Enjoy the rest of your weekend, Jason

GPON vs. GEPON
by nanog-isp＠mail.com 09 Jan '16

09 Jan '16

Hello all, For those of you with optical last mile networks that are familiar with both GPON and GEPON, would you mind sharing experiences of the differences between GPON and GEPON, especially from an operative perspective? For arguments sake let's assume bitrate, split ratio, cross vendor compatibility and purchase price differences aren't of major interest. Thanks, Jared

We are using 128 optical splits and 64 users per OLT and a mix of users buying either 100 or 1000 Mbit/s service. This just works. The system is very far from being overloaded. We would put even more users on the OLT if our vendor would allow this (they only support a max of 64 users per OLT). Remember the very first thing users do when you sell 1000 Mbit/s internet is to run a speedtest. Our users do that too and they do get the expected 940-950 Mbit/s (=gigabit ethernet wire speed) speedtest result at all time of day, also at peak usage. Regards, Baldur

Smokeping targets
by Brian R. Swan 08 Jan '16

08 Jan '16

Hi all, I’m setting up smokeping to try and gather some latency statistics on my ISP to different parts of the world. Does there exist a list or any generic recommendations of different targets to config within smokeping? Google and searching the NANOG mailing list have failed me, and I don’t want to just spam random IP addresses with ICMP requests if there’s a more official/accepted method for doing this. Thanks! Brian
