Abstract

   This memo describes an extension to the Stream Control Transmission
   Protocol (SCTP) that allows an SCTP endpoint to signal to its peer
   that it should move the cumulative ack point forward.  When both
   sides of an SCTP association support this extension, it can be used
   by an SCTP implementation to provide partially reliable data
   transmission service to an upper layer protocol.  This memo describes
   the protocol extensions, which consist of a new parameter for INIT
   and INIT ACK, and a new FORWARD TSN chunk type, and provides one
   example of a partially reliable service that can be provided to the
   upper layer via this mechanism.
