SAE J1939-31 Network Layer 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 document has been revised with some updates to address some differences between this document and some of the corresponding tests in the SAE J1939-82 document. The references to ISO 11783 within the Foreign Message Transport discussions were removed since ISO 11783 messages are transmitted as standard J1939 messages.
