===Device Description Language===
Device Description Language (DDL) allows a machine parsable description of the interface and capabilities of any device to be defined.<ref name="EngArts">{{Cite web|url=http://engarts.com/ddl/index.html|title=Device Description Language}}</ref> This description can be interpreted by a controller which may then automatically configure itself for controlling that device. The description not only provides the address and property mapping information which is necessary for DMP to operate but it can also contain a huge amount of information on the functionality, capabilities and semantics of the device in an extensible format which allows a controller to extract the features it needs for its specific context while skipping over information which is not relevant to its needs.<ref>{{Cite web |url=http://powers.media.mit.edu/wiki/upload/E1-17ACN2006DDL.pdf |title=Archived copy |access-date=2014-11-17 |archive-url=https://web.archive.org/web/20141129101447/http://powers.media.mit.edu/wiki/upload/E1-17ACN2006DDL.pdf |archive-date=2014-11-29 |url-status=dead }}</ref>
DDL is an [[XML]] based language and descriptions are contained in a small number of [[XML]] documents. In normal ACN systems the description for a device may be downloaded from the device itself. However, descriptions may also be distributed in other ways (such as internet download) and since a description is valid for all devices of the same type, controllers can typically maintain a cache of descriptions for devices they commonly encounter.

E1.31 (Streaming DMX over ACN) is supported on [[Linux]] ([[ARM architecture|ARM]], [[Intel 80386|i386]], [[x86-64]]) and [[Macintosh]] ([[PowerPC]]; i386, x86-64) by the Open Lighting Architecture.<ref>{{cite web |url=http://opendmx.net/index.php/OLA |title=Open Lighting Architecture |accessdate=2012-01-05}}</ref>
A [[Rust (programming language)|Rust]] implementation of E1.31 can be found on [[GitHub]].<ref>{{cite web |url=https://github.com/lschmierer/sacn |title=rust-sacn |website=[[GitHub]] |accessdate=2015-12-16}}</ref>
ACN has been deployed in proprietary implementations by a number of companies, including its use by Electronic Theatre Controls (ETC) as the basis of their 'NET3' branded networked control infrastructure and by [[Shure|Shure Inc.]] in control of wireless microphones.
