| dc.description.abstract | The rapid proliferation of Internet over recent years has extremely impacted the service offering. Issues of limited capacity, non-global coverage, routing and congestion challenged the availability of desired services. Particularly, burst and tremendous mass of multimedia traffic might unexpectedly congest the terrestrial network to restrict the provisions of services with desired Quality of Services (QoS). The resource utilization is then degraded. Furthermore, this unexpected congestion together with limited network bandwidth would severely challenge the provision of multicasting services that most applications adopt such as video conferencing and distance learning, especially in the case that the multicast subscribers are widely scattered. These issues have roused the research community’s interest in the integration of new satellite technologies with terrestrial multimedia networks. The satellite inherent distance insensitive network could extend the terrestrial capacity and achieve the global coverage. In addition, the terrestrial burst traffic could further detour the congestion areas by delivered to destinations over satellite networks. The unexpected congestion is then managed and the resource utilization is promoted as well. Therefore, in this dissertation, we introduce a global Satellite-Terrestrial network (ST network) configuration that integrates the broadband satellite network with the conventional terrestrial network by gateway points. Based on this platform, a resource-aware routing scheme, the Smart Hierarchical Routing Protocol (SHRP), is proposed to provide connections that detours the congestion areas. These congestion-avoided routing paths are provided for the emergent delivery or the alternatives once the terrestrial routes fail (fault tolerance). A novel proposed Spoofing RSVP Protocol (SRP) is further applied to guarantee the end-to-end QoS. In addition, in order to provide the multicast services, an Adaptive Multicast Routing (AMRST) protocol was proposed. Besides, a Spoofing Re-configurable Reliable Multicast Routing Protocol (SReRM) was further proposed to provide congestion-avoided reliable multicast services. The experimental results validate that these protocols provide excellent throughput, scalability and flexibility to this convergent network. | en_US |
