This document provides a communication model that contains the requirements for a Vehicle InterfaceProtocol (VIP) to access a vehicle interface over a network transport protocol for AMI-C networks. It does notapply to networks that have pre-existing protocols and messages for transporting vehicle functions.A VIP defines how an application communicates over a simple network transport mechanism. Theserequirements can be applied to network technologies that use UDP/IP as the transport method. However, preexistingsystems may have unique protocols and messages for transporting messages about vehiclefunctions; therefore, this document does not cover such pre-existing technology.Messages transported are network-specific instantiations of the CMS.This document addresses the following aspects related to the AMI-C’s approach to network communication:- message frame format;- application transaction;- system transaction;- initialization process;- address resolution; and- functional module discovery and removal process.
