This specification is based on IETF Request for Comments (RFC).Applicable RFCs used in this specification are listed in Section1.4. Except where necessary, information already contained in anyRFC is not duplicated within this specification, and it isrecommended that the reader obtain a copy of the applicable RFCwhen necessary.
This specification defines the broad characteristics of twotypes of networks:
1. Compliant Aircraft Data Network, referred to as CompliantNetwork.
2. Profiled Aircraft Data Network, referred to as ProfiledNetwork.
In summary, a Compliant Aircraft Data Network operates fullywithin the applicable Internet specifications as defined in therelevant IETF RFCs. A Profiled Aircraft Data Network is one inwhich one or more industry standard protocols have been extended toaddress unique problems of the avionics industry.
Interoperability between a Compliant Network and a ProfiledNetwork, or between Profiled Network systems with differentcharacteristics, is not assured without the use of an intermediatesystem, such as a router or gateway. In addition, a ProfiledNetwork may provide some characteristics typical of a CompliantNetwork to a User Application (UA); but the fundamental orunderlying behavior of the network may not be identical.
Purpose of Document
This document specifies a profile of Internet Engineering TaskForce (IETF) standard protocols and services for use on boardaircraft. It is the intent of this specification to define thefunctionality of standard Internet protocols and services in amanner that allows interoperability of components connected toonboard data networks while simultaneously being totallyindependent of functionality. Not all functions of a “standard”Commercial Off the Shelf (COTS) implementation may be useful, orappropriate, for all onboard networks. However, by implementing a”proper subset” of Internet standards the goal of maximuminteroperability balanced with cost of implementation andcertification can be achieved.
