SAE J1939-81网络管理定义了与管理在SAE J1939网络上通信的应用程序源地址相关的过程和消息。网络管理涉及源地址的管理，以及这些地址与实际功能的关联，以及网络相关错误的检测和报告。由于源地址管理的性质，网络管理还规定了初始化过程、对短暂停电的反应要求以及对网络上ECU的最低要求。

SAE J1939-81 Network Management defines the processes and messages associated with managing the source addresses of applications communicating on an SAE J1939 network. Network management is concerned with the management of source addresses and the association of those addresses with an actual function and with the detection and reporting of network related errors. Due to the nature of management of source addresses, network management also specifies initialization processes, requirements for reaction to brief power outages and minimum requirements for ECUs on the network.
