This feature is new in the Solaris Express 8/04 release.
Stream Control Transmission Protocol (SCTP) is a reliable transport protocol that is now included in the Solaris Operating System's TCP/IP protocol stack. SCTP provides services that are similar to TCP. However, SCTP supports connections between endpoints that are multihomed, that is, with more than one IP address. The support for multihoming makes SCTP a popular transport protocol for telephony applications. SCTP also supports multistreaming and partial reliability.
The SCTP protocol does not require additional configuration after the Solaris 10 OS is installed. However, you might need to add service definitions, so that particular applications can run over SCTP.
For information about configuring SCTP, refer to the System Administration Guide: IP Services.
