In this paper, we evaluate the performance of Stream Control Transmission Protocol (SCTP) with adaptive multistreaming which we had previously proposed. This proposed modification can be useful for the resource limited mobile terminals in LEO satellite networks. In the proposed modification, a SCTP sender adaptively enables or disables multistreaming based on the comparison between the estimate of available bandwidth and current congestion window size. By doing this, user terminals use multistreaming feature appropriately and can avoid waste of resource caused by unnecessary use of multistreaming. In this paper, we propose a further modification to the adaptive multistreaming and evaluate its performance.
