One of the main objectives of so-called next generation systems is to overcome the limitations of today's available Internet by adopting an approach based on the integration of different mobile (both satellite and terrestrial) and fixed networks. The Global Mobile Broadband System (GMBS) proposed by the SUITED project moves in this direction. The Q...

... the federated ISP network, towards the correct GGSN or satellite Fixed Earth Station (FES). As soon as the GGSN or the FES receives these IP packets, the routing towards the mobile router is in charge of the access segment specific entities. The MR performs registration towards the MRHA while each MH performs registration towards its own MHHA. Fig. 2 depicts an example of MIP architecture for the proposed scenario by highlighting, in particular, the structure of the routing tables of the nodes implementing MIP protocol. The MRHA implements, among the others, the functionality required to execute the QoS-aware inter-segment handover, i.e. a procedure which allows to seamlessly ...

Mobile applications are becoming increasingly more complex and making heavier demands on local system resources. Moreover, mobile systems are nowadays more open, allowing users to add more and more applications, including third-party developed ones. In this perspective, it is increasingly expected that users will want to execute in their devices ap...

For decades, the development of the Internet was driven by the purpose of providing applications to non‐mobile users. No specific Quality of Service (QoS) requirement is necessary, other than ensuring reliability in the end‐to‐end data transfers. As such, best effort service model was deemed more than appropriate to satisfy the users' needs. Nevertheless, the scenario has changed in the last few years. A new population of nomadic users, who requires access to Internet services regardless of their location and mode of transportation is growing, while new typologies of Internet applications are being continuously developed, in which best effort service level may no longer be adequate.
The SUITED project has been devised to address the emerging issues generated by this new and challenging scenario. SUITED aims at contributing towards the design and deployment of the Global Mobile Broadband System (GMBS), a unique satellite/terrestrial infrastructure, which will ensure that nomadic users have access to Internet services with a negotiated QoS. An overview of the main results achieved in the SUITED project is provided in this article. Some of the most innovative solutions developed by the SUITED team for the joint management of global mobility and end‐to‐end QoS support are presented. The SUITED demonstrator platform, which was developed to validate the system specifications, is also described. Finally, the results of the experimental measurement campaigns carried out with this platform are reported. Copyright © 2004 John Wiley & Sons, Ltd.
