The scope of this document is to set a framework for the context@ application and interactions of the ESNI protocol suite. It shows how each protocol@ ESMI@ EISI and ENEN relates to the other. It will describe how services may be accessed in a mediated or unmediated fashion. In doing this it will use some examples of services for each environment. This document@ in itself does not define the standards for the protocols. Those are defined in each document associated with the specific protocol. It does frame the use and applicability of each protocol.
