A model for multimedia service creation and activation

The emergence of multimedia applications requires appropriate management and control activities to be provided and organized in an integrated framework. This paper presents an architectural approach for the modeling of service activation processing in a multimedia environment. In particular, activation processes complying with this model provide the user with the capability of devising, creating and controlling the required composite multimedia service by using elementary services provided by the network as building blocks. The model introduced in the paper has been effectively used as a basis for the development of a network environment providing prototypal services of Multimedia Cooperative Editing (MCE)
