ISO/IEC 14908-4:2011 specifies the transporting of the Control Network Protocol (CNP) packets for commercial local area control networks over Internet Protocol (IP) networks using a tunnelling mechanism wherein the CNP packets are encapsulated within IP packets. It applies to both CNP nodes and CNP routers. The purpose of ISO/IEC 14908-4:2011 is to ensure interoperability between various CNP devices that wish to use IP networks to communicate using the CNP.

Overview

ISO/IEC 14908-4:2012 - Information technology - Control network protocol - Part 4: IP communication - specifies how the Control Network Protocol (CNP) is transported over Internet Protocol (IP) networks. The standard defines a tunnelling mechanism in which CNP packets are encapsulated inside IP packets to create an IP channel that behaves as a CNP transport. It applies to both CNP nodes and CNP routers and is intended to ensure interoperability between CNP devices that use IP networks to exchange control messages.

Key topics and technical requirements

The standard focuses on the reliable, efficient transport of CNP over IP. Major technical topics include:

Tunnelling and encapsulation

Encapsulation of CNP packets within IP packets to form an IP channel equivalent to other CNP media.

CNP/IP device behavior

Requirements for CNP/IP nodes and routers to operate as standard IP hosts and exchange CNP packets across IP subnets or the Internet.

Message and packet structures

Definitions for CNP/IP message types, common headers, segmentation, packet formats and sequence handling (see normative packet format sections).

Ordering, timeout and duplicate detection

Preserve CNP packet ordering, discard stale packets, and detect duplicated packets introduced by IP transport.

Performance and scalability

Efficient operation to support quasi real‑time control traffic and support for prioritized IP routing.

Configuration and management

Protocols for interactions with configuration servers, device registration, channel membership, routing updates, and status/health reporting.

Optional security

Support for optional authentication and security mechanisms to protect against tampering (security is optional and implementation-dependent).

Interoperability constraints

The specification is independent of the higher-level CNP application interface and does not cover lower-layer physical/MAC details or cross‑channel routing logic.

Practical applications - who uses this standard

ISO/IEC 14908-4:2012 is primarily used by manufacturers, integrators and engineers working on commercial local area control networks, including:

Building automation (HVAC, lighting, access control)

Facility and energy management systems

Industrial and commercial control systems that require vendor-neutral CNP interoperability over IP

Developers of CNP/IP nodes, routers, gateways and configuration servers

Adoption ensures devices from different vendors can communicate reliably over IP while preserving CNP semantics.
