The approach presented in this paper aims to obtain a QoS for IPv6 protocol over LEO satellites. Most of the switching and access operations in the proposed system will require the intelligent functions to be located on Earth. We can allocate links at different bit-rates and no particular assumptions have been made as concerns the access protocol in order to maintain the presented work at a general level. Both controlled load and not-controlled load traffic have been considered. The behavior of the proposed system shows that the utilization and the delays are strictly related. The simulations show that large delays correspond to small values of utilization while short delays have the drawbacks of bandwidth wastage. The results point out that, as concerns the privileged traffic classes of NCL are subject to delays very close to those obtained by the CL traffic while maintaining high link utilizations
