The current HTTP over SCTP design
exploits SCTP streams to avoid
head-of-line blocking. SCTP also offers other services unavailable in TCP such
as unordered delivery, partially reliable transmission, message based transfer,
multihoming support, more secure connection establishment with a cookie
mechanism and so on. We plan on adapting our design proposal to leverage
some/all of these SCTP services in the future.
We implemented HTTP over SCTP streams in Apache and
Firefox. Experiments show significant improvements to end user
performance in networks with high
latency and/or lossy paths. (I can point you to relevant material if you
are interested in knowing more.)
interested in submitting our code changes to APR and httpd. We'd very
much appreciate guidance from httpd and APR developers on our mods
and the submission process.
