... and high costs in using these links for experiments. We however believe that the obtained results may provide good insights also for general networks (including satellite links) in particular for ... for managing inter-domain communications with neighbor QoS brokers, so that QoS-enabled transport services are implemented in a coordinated way across various domains. Since IntServ req...

... combining, etc., are discussed in the scenario of satellite systems. What is interesting in our context is the overview of cross-layer design methods employed in satellite systems, in particular ... transmission rate being used at the link layer. Moreover, the network layer can gain by looking both up and down the stack in order to obtain route diversity and multilink routing, w...

... attenuation (due to changing slant path), blocking (due to obstacles in the Line of Sight, LoS), multipath fading, and changing satellite distance. Internet has been conceived assuming that Packet Error ... start threshold (ssthresh). In particular, each sending end-system probes the network congestion by gradually increasing the window of transmitted segments (outstanding in the netw...

... efficiency. In the forward link, the introduction of spreading requires the design of a new DVB-S2 receiver. In the return link, each terminal could in principle implement direct spreading within the ... 51, 100, 110 , 177, 179, 184, 189, 199, 257 Complete partitioning, 52, 179 Complete sharing, 52, 179 Call handover, 53, 189, 195, 214, 233 Inter -satellite handover, 54, 190, 194, 214 I...
