Riassunto analitico
The thesis aims to investigate a hybrid network in which a Satellite overlay cooperates with a pre-existing CDN terrestial network. A new method of popularity generation along with a hybrid placement algorithm are presented in order to optimize QoE perceived by users ans bandwidth consumption.
Performance is evaluated in terms of hit ratio and time placement. The hybrid approach shows significant improvements compared to the single terrestrial or satellite network.
