Full title and description

ANSI E1.11-2024 — Entertainment Technology — Recommended Practice for Architecture for Control Networks (sACN), commonly known as "Streaming ACN" (sACN). This standard specifies a network protocol for the transport of real-time entertainment lighting control data over IP networks, defining data formats, packet types, universe addressing and mechanisms to ensure interoperability between lighting controllers, fixtures and media servers.

Abstract

ANSI E1.11-2024 defines the Streaming Architecture for Control Networks (sACN), a layered protocol that carries DMX-style channel-based lighting control data over standard IP-based Ethernet networks. The standard describes packet structures, timing, priority and synchronization behaviors, universe and source identification, and recommended practices for reliable distribution of live lighting control information in theatrical, concert, architectural and broadcast environments.

Scope

This standard specifies the protocol and recommended practices for transmitting channel-based lighting control data over IP networks using the Streaming ACN (sACN) method. It covers data packet formats, timing and refresh behavior, universe addressing, source and priority mechanisms, synchronization and sequencing, and interoperability requirements to allow multiple manufacturers' devices (consoles, processors, pixel controllers, LED drivers, and media servers) to exchange live control data reliably on Ethernet-based infrastructures.

Key topics and requirements

• Definition of sACN packet formats and fields, including framing, sequence numbers and synchronization.
• Universe addressing and mapping of channel data onto IP and multicast addresses.
• Priority and source arbitration for competing data sources.
• Timing, packet rate, and latency recommendations to maintain smooth real-time control.
• Requirements for use of multicast and unicast transport, and recommended network practices (IGMP, TTL).
• Guidance on interoperability, device identification and diagnostics.
• Security and robustness recommendations for live-event networks (basic best practices; not a security specification).

Typical use and users

Engineers, lighting designers, system integrators, and manufacturers in the entertainment, theatrical, concert touring, architectural lighting and broadcast industries use ANSI E1.11-2024. It is applied when designing networked lighting control systems, developing hardware or software that processes DMX-style data over IP, creating fixtures, pixel-mapping devices, or when configuring venue networks to ensure reliable interoperation of control consoles, media servers and dimming/LED controllers.

Related standards

ANSI E1.11 is commonly used alongside other entertainment technology standards such as ANSI E1.20 (RDM over IP/Streaming protocols where applicable), ANSI E1.17 (ACN, Architecture for Control Networks), ANSI E1.27 (Ethernet-based protocols for specific uses), the DMX512 family (ANSI E1.11 related to DMX512 data model), and network standards like IEEE 802.3 (Ethernet) and RFC recommendations for multicast and UDP/IP transport.
