Web services for the new internet: discussion and evaluation of the provisioning of interdomain services

In these last few years, the Internet as it is today has put some limitations on the evolution of new services. Problems such as address space scarcity, mobility, sensor networks and VoIP are becoming common requirements now and will be more frequent in future. However, the current Internet architecture does not support this evolution. In 2003, Jon Crowcroft [1] discussed the problems of the Internet Architecture. In January 2005, a report from NSF [2] addressed the barriers that need to be faced in order to overcome limitations towards a new internetworking architecture. In this paper, we discuss how Web services can be useful in solving some interdomain problems. The strong interaction between ISPs already exists and will be more necessary as new services appear. We believe that the Web services solution is a facilitator in this path. Our discussion is supported by the CANARIE [3] research point of view that everything is a service. We use this idea in the context of interdomain interactions where each domain is then seen as a service. We developed an architecture to support these interactions and evaluated the prototype in terms of time and bandwidth consumption to provide interdomain services.
