IEEE 2030.5-2013

With respect to the OSI network model, the Smart Energy Profile 2.0 Application Protocol is built using the four layer Internet stack model. This specification defines the ‘APPLICATION’ layer with TCP/IP providing functions in the ‘TRANSPORT’ and ‘INTERNET’ layers. Depending on the physical layer in use (e.g., 802.15.4, 802.11, 1901), a variety of lower layer protocols may be involved in providing a complete solution. Generally, lower layer protocols are not discussed in this document except where there is a direct interaction with the application protocol. The scope of this document is defining the mechanisms for exchanging application messages, the exact messages exchanged including error messages, and the security features used to protect the application messages.
