适用范围：This part of ISO/IEC 14543 specifies the services and protocol in a manner independent of thephysical layer for the data link layer and for the network layer and the transport layer for usage innetwork enhanced home electronic systems Class 1.ISO/IEC 14543-4 is designed to enable the use of power line and wireless protocols as transmissionmedia. Slow transmission speeds discourage large data transfers, and it is desirable to reduce themounting load on simple devices. In light of this situation, this part of ISO/IEC 14543 specifies theframe format for the communications middleware block to minimize message size while fulfilling therequirements of the communications layer structure.This part of ISO/IEC 14543 specifies the protocol difference absorption processing block and a part ofthe communications processing block. Figure 1 shows the relationship between the protocol ofISO/IEC 14543-4 and HES reference model based on ISO/IEC 7498.Figure I - Relationship between the protocol of ISO/IEC 14543-4 and OSI reference model
