A terminal device transmits, upon a launch of an application frontend of a distributed application, a lookup request based on a predetermined fully qualified domain name associated with an application backend of the distributed application to a domain name server via a communication network. Upon receipt of the fully qualified domain name, the domain name server transmits an IP address associated with the fully qualified domain name to the application frontend. Upon receipt of the IP address, the terminal device transmits application data to the transmitted IP address via a connection provided by the communication network. Upon transmission of the application data, the core server selects a quality service for the distributed application, which is then applied by the communication network for operation of the distributed application.
