ISO/IEC 29341-27-1:2017 is compliant with the UPnP Device Architecture version 1.0. It defines a service type referred to herein as FriendlyInfoUpdate service . It is scoped to the Device Description Document (DDD) and is a service allowing control points to create orderly updates to the and elements. Once a change has taken place the status of the DDD might not reflect that of the advertised description because the device can not leave the network during ongoing activities. Therefore a state variable is provided to indicate if the DDD contains non-advertised (pending) values. If for any reason the device goes off line, power cycles, or reboots it will most likely advertise its new DDD. If DeviceProtection UPnP DP is implemented on the device then it will support restricting control point actions to control points with specific Roles.
