Quality-of-service measurement of satellite-based international packet-switched networks
Abstract
Satellites are increasingly being used to provide international packet-switching services. CCITT Recommendation X.135 specifies the minimum quality requirements that must be met when providing such services. To verify the correctness and feasibility of these requirements, quality-of-service measurements were performed for two experimental configurations. The first involved one satellite link, one transatlantic cable link, and one transit network. The second used two satellite links and one transit network. The parameters measured included throughput capacity, connection establishment delay, connection release delay, and data packet transfer delay. The results demonstrate that the performance of packet-switched services over international satellite links is well within the specified requirements. It was also shown that components other than satellite propagation delay (such as nodal processing delay and transmission delay) contribute significantly to the overall delay.
