Network Layer
Description / Abstract:
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.
