Editing DOCSIS (section)

===Comparison===
Several DOCSIS versions can co exist by using frequency division multiplexing and separating new DOCSIS versions from old ones according to their operation frequencies.<ref>{{cite web |last=Downey |first=John J. |date=July 31, 2014 |title=DOCSIS 3.1 Overview |url=https://www.piedmontscte.org/resources/july2014/D3.1-Overview-JJD-073114.pptx |website=PiedmontSCTE.org |access-date=October 24, 2024 }}</ref>

|-
| 1.0
| <!-- March -->1997
| rowspan="3" | 40&nbsp;Mbit/s
| rowspan="2" | 10&nbsp;Mbit/s
| Initial release
|-
| 1.1
| 2001<!-- Not the same as other sources (April 1999)? -->
| Added VOIP capabilities and QoS mechanisms
|-
| 2.0
| 2002<!-- Not the same as other sources (December 2001)? -->
| 30&nbsp;Mbit/s
| Enhanced upstream data rates
|-
| 3.0
| <!-- August -->2006
| 1&nbsp;Gbit/s<!-- Note that both of these are the WHOLE-NODE bandwidth totals, and for this case this is approximately but not exactly the maximum attainable under BEST-POSSIBLE-CASE conditions (minimum maximum conditions under the spec are closer to 160/120 (4/4 bonded), while best-case is a 32/8 bonded connection producing 1200/200). -->
| 200&nbsp;Mbit/s
| Significantly increased downstream and upstream data rates, introduced support for IPv6, introduced [[channel bonding]]
|-
| 3.1
| <!-- October -->2013
| rowspan="2" | 10&nbsp;Gbit/s<!-- Note that both of these are the WHOLE-NODE bandwidth totals, using standardized and somewhat idealized assumptions w.r.t. bandwidth availability and spectrum allocation. However, maximums under certain conditions (wider spectrum, higher QAM utilized, etc.) CAN (significantly) exceed these numbers! -->
| 1–2&nbsp;Gbit/s
| Significantly increased downstream and upstream data rates, restructured channel specifications
|-
| 4.0
| 2017<!-- Cable labs released the spec for use in October 2017. -->
| 6&nbsp;Gbit/s
| Significantly increased upstream rates from DOCSIS 3.1
