DMTF’s Network Controller Sideband Interface (NC-SI) standard has been adopted and published by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) as ISO/IEC 24079:2024.

NC-SI is a common interoperable sideband interface and protocol used to transfer management traffic between a management controller and a network controller (NC). It defines the functionality and behavior of the Sideband Interface responsible for connecting the NC (including Ethernet, Fibre Channel, and InfiniBand controllers) to the management controller and can be transported via MCTP or RMII based Transport. The NC-SI enables a shared NIC model, which eliminates the need for separate management of network traffic as well as the need for additional switches, cables, or RAC infrastructure.

In addition to NC-SI, DMTF has a wide breadth of standards that have achieved important international accreditation status. To view the full list, please visit the DMTF ANSI and ISO Adoptions and Alliance Activities page.
