DMTF announces the public release of the MCTP over USB Binding Specification (DSP0283) Work in Progress and is now available for download. This WIP defines a transport binding for facilitating MCTP communication between platform management system components (i.e. management controllers, management devices) over USB 2.0.

The MCTP Base Specification describes the protocol and commands used for communication within and initialization of an MCTP network. The MCTP over USB 2.0 transport binding definition in this specification includes a packet format, USB endpoint descriptors, message routing, and discovery mechanisms for MCTP over USB communications.

Designed to be referenced by other standards organizations and developers, DMTF invites public comment on the MCTP over USB Binding Specification WIP before finalization. Feedback may be submitted on our website at https://www.dmtf.org/standards/feedback/.
