[Cerowrt-devel] A nice blog comparing two DOCSIS 3.0 cable modems

[Erkki Lintunen <ebirdie@iki.fi>]

May be of interest to some of you on the list:

<http://blog.mycre.ws/articles/cable-modems-arris-sb6190-vs-netgear-cm600/>

Some points for a summarization:

* author did not measure Bufferbloat
* made a note about difference in latency
* measurements done w. SmokePing
* measurements against ISP's recursive DNS server (as target doubtful, may 
  have heavy traffic shaping/limiting)
* the author's premise to hw was to exclude integrated router or AP function 
  in the modem (I like)
* and support 24 downstream channels at least 
* hw1: Arris SB6190 with a Linux system and source available
* hw2: Netgear CM600 with an eCos system and older fw source available
* Arris got into problems after a few days of operation
* further hw info nicely linked
* the author hints the ISP manages the cable modem fw 
* the author chose to go on with Netgear
* gives a view of status of the cable modem availability and quality w. 
  a certain hw criteria

The author could be hinted to use either Flent (against netperf.bufferbloat.net) or Speedtest of DSLReports.
