Purpose: The intent of this document is to provide general andspecific design guidance for the development and implementation ofan On-board Local Area Network (OLAN) for use in an aeronauticalOpen Systems Interconnection (OSI) communications environment. Onlythe Physical Layer and Data Link Layer of the OSI Basic ReferenceModel (ISO 7498) are specified by this document. The network andupper layers are defined in ARINC Specifications 637 and 638respectively. This Specification embraces internationally recognizedstandard protocols and provides a very high bandwidth digital datanetwork to interconnect avionics systems. It is expected that othernetworks such as the Aeronautical Telecommunications Network (ATN)will use OLAN and thus, the use of standard protocols will simplifythe interconnection to these other networks and minimize the use ofgateways or other types of protocol converters.
