In the worst case, a datagram's arrival will be MGD times the number of nodes traversed. The MGD bound will not be affected by the amount of traffic in the net. During non-busy hours, the delay provided should be better than the guarantee. If however, the MGD is less than the satellite link can provide, it should not be used. For this discussion it is assumed that delay for individual links are low enough that a sending node can provide the MGD service.
Class of service is unidirectional.
The performance of TCP might be significantly improved with an accurate estimate of the round trip time and the retransmission timeout. The timeout value would have to be redetermined when the number of hops in the route changes. High throughput class of service should get a large volume of data through the Internet. Requesters of this class are less concerned with the delay the datagrams have crossing the Internet and the reliability of their delivery. This type of traffic might be served well by a satellite link, especially if the bandwidth is high.
