YD/T 7009-2026 is the English-translated version of 基于SDN的时间同步设备管控系统北向接口技术要求.

YD/T 7009-2026 specifies the technical requirements for the northbound interface of a time synchronization equipment management and control system based on Software Defined Networking (SDN). It mainly covers the overall management and control architecture of the time synchronization network, the functional requirements of the northbound interface, the interface protocol, the interface data structure and the interface definition. It applies to the design, development and testing of the northbound SDN interface of time synchronization equipment management and control systems.

Manufacturers of time synchronization equipment, developers of management and control software, telecommunications operators and test laboratories are typical users. The standard is voluntary, as the /T in its code shows. The Ministry of Industry and Information Technology issued it on 1 June 2026, and it takes effect on 1 September 2026. It is a new standard, with no earlier edition replaced.
