This is achieved by introducing a signalling scheme enabling the application to automati- cally negotiate with the network the transport resources they require. The signalling workow is detailed and the scalability of the proposed solution is evaluated through an experimental test-bed.

Introduction The current Internet offers an end-to-end transport service able to interconnect different and heterogeneous applications on top of a flat network layer focusing on packet routing. IP provided a unified access to networking facilities and has indeed been the stronghold of the Internet success. Nonetheless, the effectiveness of this approach is starting to vanish today, as a consequence of the introduction in the network of functions and sub-blocks (e.g., NATs, firewalls or even application layer switching) not envisaged at the time IP was designed [1]. As a result the transparent access to the networking technology is vanishing and applications need to be more and more network-aware. This goes together with the evolution of the applications towards often requiring effective support of Quality of Ser- vice (QoS) and large scale bandwidth provisioning from the network. The deployment of new communication services (as well as communication service management) must take the aforementioned issues into account. In current scenarios, applications typically talk end-to-end and resource manage- ment is provided by means of centralized application services (e.g. web-services in Grid computing [2]). This is a typical overlay approach, that may result in inefficiencies in the use of the network resources and in limited functionalities. A more integrated and effective approach assumes that the current Internet evolves into a more application- aware networking infrastructure. To this end a whole set of new signalling schemes has to be conceived, which enables the applications to interact with the network and to negotiate the resources needed to activate the requested communication service. Therefore the Future Internet should be more service-aware, providing built-in func- tionalities to match communication resources with service requests [3].
