To ensure an interoperable, scalable, and manageable network, certain networking services need to be standardised, including address assignment, HostName resolution, and topology discovery. In addition, limits on various network quantities, such as the number of IA-stations, network diameter, and, if used, TSN Streams need to be defined to set capability expectations. Note that some of these services and quantities relate more to the network infrastructure than to the responsibilities of individual IA-stations participating in the network.
