Abstract
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 waste. 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.
