Description: Problem with SOAP address of services on a device
Document: wsdd-dpws-1.1-spec-wd-02
Line number:

There is the following scenario: A client is using a service on a device. This device leaves network and can't send a bye message. A new device joins network. The new device hosts a service of the same type that has the same transport address as the service before. The new device sends a hello message. The client won't be able to detect that it uses another instance of the service, that is hosted on another device.

Proposed solution: Service addresses should include the device id or should be unique.
