Information technology - Home electronic system (HES) architecture - Part 4-2: Communication layers - Transport, network and general parts of data link layer for network enhanced control devices of HES Class 1
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 inHome Electronic Systems.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 14543-4 specifies theframe format for the Communications Middleware Block to minimize message size while fulfilling therequirements of the communications layer structure.
