Abstract: Various communication systems may benefit from an improved cloud verification platform. For example, a cloud verification platform that can test and verify the underlying cloud infrastructure on behalf of the cloud application in an automated and systematic fashion may be helpful. A method may include connecting to a cloud verification service for testing a cloud infrastructure. The method may also include triggering execution of a virtual network function on the cloud infrastructure. In addition, the method may include testing a key attribute of the cloud infrastructure with the executed virtual network function using the cloud verification service. Further, the method may include sending a metric of the key attribute of the cloud infrastructure or the virtual network function to a user equipment.

Abstract: The invention relates to an application server and a method. The application server comprises a resolver which reserves a subscriber number prefix for test target applications. The resolver associates an address of an application server with the prefix in a memory and resolves subscriber numbers containing the prefix into the address using the memory. A network element simulator listens to a port, which has a port number which is also used in communicating with the network element being simulated. A test target application communicates with the simulator instead of the network element being simulated via a protocol stack in the application server. An application layer binding is used to route incoming messages to the test target application.
