6 Device communication model

6.3 Network

A Network is the logical representation of wired and wireless technologies and represents the communication means for Devices that are connected to it. A Network instance is qualified by its Communication Profile components.
Figure 22 shows the type hierarchy and the NetworkType components. It is formally defined in Table 37.

HasComponent | Object | <ProfileIdentifier> | ProtocolType | MandatoryPlaceholder | |
ConnectsTo | Object | <CPIdentifier> | ConnectionPointType | OptionalPlaceholder | |
HasComponent | Object | Lock | LockingServicesType | Optional |
The <ProfileIdentifier> specifies the Protocol and Communication Profile that this Network is used for.
<CPIdentifier> (referenced by a ConnectsTo Reference) references the ConnectionPoint(s) that have been configured for this Network. All ConnectionPoints shall adhere to the same Protocol as the Network. See also Figure 25 for a usage example. They represent the protocol-specific access points for the connected Devices.
In addition, Networks may also support LockingServices (defined in 8.3).
