IEEE P2030.5 DRAFT

Description / Abstract: 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 completesolution. 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 22 features used to protect the application messages.

Purpose

The purpose of this document is to define the application protocol used by the Smart Energy Profile release 2.0. The Smart Energy Profile Application Protocol 2.0 is designed to meet the requirements stated in the Smart Energy Profile 2.0 Marketing Requirements Document (SEP 2 MRD) [ZB 09-5162] and the Smart Energy Profile 2.0 Technical Requirements Document (SEP 2 TRD) [ZB 09-5449]. Per Req[DataModel- 1], this application protocol is an IEC 61968 common information model [61968] profile, mapping directly where possible, and using subsets and extensions where needed, and follows a RESTful architecture [REST].
