In this paper, the authors proposed transmission of streaming media passed through a Stream Control Transmission Protocol (SCTP). This paper evaluates the performance of the SCTP with adaptive streams. This is done by adding new methods for setting the number of streams, that can be applied to an SCTP and that can utilize new, characteristic of SCTP features. A SCTP sender adaptively enables or disables multi-streaming based on comparison between the estimates of available bandwidth and current congestion window size. It is desired to improve goodput under congestion.
