1.1 Embedding of the Network Management (NM)NM defines a set of services for node monitoring. Figure 1 shows how the NM is embedded into a system andthat the NM shall be adapted to specific requirements of the bus system used or to the resources of the nodes.NM consists of the following:-- interface to interact with the Application Programming Interface(API);-- algorithm for node monitoring;-- internal interfaces (NM <-> COM, etc.);-- algorithm for transition into sleep mode; and-- NM protocol data unit (NMPDU).1.2 Adaptation to bus protocol specific requirementsAdaptation to bus protocol specific requirements consists of the following:-- CAN, VAN, J1850, K-BUS, D2B, etc.;-- error handling, e.g. bus-off handling in a CAN, transmission line error handling; and-- interpretation of the status information, e.g. overrun or error active/passive in a CAN.1.3 Adaptation to node resourcesAdaptation to node resources consists of the following:-- scaling of the NM as a requirement of the node; and-- application-specific usage of the NM services.1.4 Adaptation to hardware-specific requirementsThis consists of adaptation to a protocol circuit and a physical layer circuit, e.g. switching the bus hardware toone of the possible physically power save modes.1.5 Station management (system-specific algorithms)There are a variety of additional tasks involved in coordinating a network. These are not described inISO 17356, since they are system-dependent. Hence, these tasks are done by the application, e.g. by amodule called station management.1.6 Philosophy of node monitoringNode monitoring is used to inform the application about the nodes on the network. Thus, the application cancheck with the appropriate service if all stations required for operation are present on the network.
