The Network Layer document describes the requirements and services for Network Interconnection ECUs (NIECU) that enable electronic control units (ECUs) on a network segment to intercommunicate with other ECUs on different network segments of the vehicle network. This document defines various types of NIECUs. The information in this document applies only to ECUs that are intended to provide networking services. It is not necessary for an ECU to provide any of these services in order to be compliant with the SAE J1939 protocol. This SAE Recommended Practice was reviewed as part of the 5-year review cycle, resulting in several updates to this document. The most significant change in this update involves reorganizing the contents to minimize duplication of technical data and localize related technical data. Other notable changes include clarification of the definitions for NIECU parametric data parameters, clarification of definition details for each Network Message function, definitions for each of the Network Message parameters, and expanded discussion of Foreign Message Transport.
