This document updates RFC 4960 by defining a method for the sender of
a DATA chunk to indicate that the corresponding Selective
Acknowledgment (SACK) chunk should be sent back immediately and
should not be delayed.  It is done by specifying a bit in the DATA
chunk header, called the (I)mmediate bit, which can get set by either
the Stream Control Transmission Protocol (SCTP) implementation or the
application using an SCTP stack.  Since unknown flags in chunk
headers are ignored by SCTP implementations, this extension does not
introduce any interoperability problems.

This document is a product of the Transport Area Working Group Working Group of the IETF.

This is now a Proposed Standard.
