Overview
ISO/IEC 17811-2:2015 specifies the Device Control and Management Protocol (DCMP), an application-layer protocol for controlling and managing diverse networked devices. Part of the ISO/IEC 17811 family, this standard defines DCMP protocol operations, message structure, payload formats and parameter details used for device discovery, status retrieval, firmware/software updates, file transfer, registration, event notification and other management services. The specification assumes reliable delivery is provided by the companion RMDP protocol (Reliable Message Delivery Protocol).
Key topics and technical requirements
- Protocol operations: defined operations include Device Discovery, Device Advertisement, Device Information Retrieval, Device Control, Event Notification and Subscription, Get File Information, File Download/Upload, Apply, Device Registration and Service Registration.
- Message structure: DCMP message formats, payload messages and error types are specified; Annexes include unit/device type codes and XML schema examples for payload messages.
- Interaction with RMDP: DCMP operates over RMDP for reliable message delivery and uses RMDP to map device identifiers to network addresses (IP/port).
- Administrative concepts: Definitions and roles such as Device Management Server (DMS), administrative domain and device identifiers are included.
- Security: Network security mechanisms are explicitly out of scope for Part 2; however, the standard acknowledges that DCMP deployments may require security services and recommends applying appropriate protection against network-specific threats.
- Intellectual property: The document notes a claimed patent relevant to the DCMP message structure (patent holder: ETRI) and directs implementers to patent databases for details.
Practical applications and who uses it
ISO/IEC 17811-2:2015 and the DCMP specification are practical for:
- Device manufacturers implementing standardized remote control and management interfaces (firmware/software update, device initialization).
- IoT solution providers and system integrators building interoperable device management systems.
- Developers of Device Management Servers (DMS) and gateway/RMDP implementations that require reliable mapping and delivery of DCMP messages.
- Network and operations teams implementing large-scale device provisioning, monitoring, file distribution and event-driven management.
- Standards engineers ensuring interoperability across heterogeneous device fleets.
Benefits include standardized device discovery, consistent file transfer and update procedures, and a defined message model that aids integration between devices and management servers.
