Theory on Platform Management Communications Infrastructure

Abstract: Platform Management Communications Infrastructure (PMCI) Working Group develops standards for "inside the box" communication between platform management subsystem components. The Network Controller Sideband Interface (NCSI), Management Component Transport Protocol (MCTP), Platform Level Data Model (PLDM), and Security Protocol and Data Model (SPDM)are the standards that are developed by the PMCI group. These standards enable monitoring and control of systems regardless of the status of the operating system, whether it is running or not. This Paper Discusses how these four specifications effect on platform management subsystem.

Keywords: PMCI, NC-SI, MCTP, PLDM, SPDM, platform management subsystem.
