3.1.1 Abstract Data Model

This section describes a conceptual model of possible data organization that an implementation maintains to participate in this protocol. The described organization is provided to facilitate the explanation of how the protocol behaves. This document does not mandate that implementations adhere to this model as long as their external behavior is consistent with that described in this document.

The following is a list of the abstract data model elements maintained by the WFDA2A protocol for each proximate device:

Advertisement data:  The device’s Display Name, Peer ID, Role, Version, and optional Metadata.

Connection data:  The IP address, port number, and listener intent

Handshake data:  The Session ID (derived from the WFD PSK) and the Connection Type.
