DMTF announces the public release of its Management Component Transport Protocol (MCTP) Host Interface Specification version 2.0.0 (DSP0256). This specification is the latest generation of transport protocols developed by the Platform Management Communications Infrastructure (PMCI) Working Group.
The MCTP Host Interface Specification 2.0 introduces major improvements to the discoverability of MCTP communication from the host software.
Version 2.0 enhances version 1.0, extending the definition to enable MCTP communication over a variety of physical interfaces, such as I2C/SMbus, I3C, USB, PCIe VDM, as well as the newly defined MCTP over Memory-Mapped Buffer Interface (MMBI) and upcoming Platform Communication Channel (PCC).
