Stream Control Transmission Protocol (SCTP) is a standard Internet protocol originally designed to transport signalling messages over IP networks. It has been developed and extended to support partially reliable and partially ordered traffic requirements. So far, in-depth unreliable ordered time sensitive traffic performance issues in SCTP have not been addressed. This paper proposes protocol extensions for such traffic and evaluates them by analytical and simulation means.
