SCTP over satellite networks

Abstract

The stream control transmission protocol (SCTP) has recently been standardized as a new transport layer protocol in the IP suite. In addition to the core features of TCP, SCTP incorporates a number of advanced and unique features which are not available in TCP. The paper investigates the suitability of SCTP for data communications over satellite links. We describe SCTP features that allow SCTP to utilize the bandwidth of satellite networks better, while at the same time avoiding congestion collapse in a shared network. Finally, we provide recommendations on the use of SCTP over satellite networks.
