Hi all. I have uploaded a new revision of the QCRAM draft.
Highlights of 01->02:
- more concise: lines of text down ~ 30%.
- simplifications:
- flexibility to trade-off between compression ratio and HoL blocking
resilience.
- handling stream reset, dropped QPACK style split between updates
and encoded headers.
- new eviction scheme, avoids eviction races and icky resets.
- mostly eliminated coordinated packetization (just a note in
performance section now).

Revision: 02
Title: Header Compression for HTTP over QUIC

Pages: 8

Abstract:
The design of the core QUIC transport and the mapping of HTTP
semantics over it subsume many HTTP/2 features, prominent among them
stream multiplexing and HTTP header compression. A key advantage of
the QUIC transport is it provides stream multiplexing free of HoL
blocking between streams, while in HTTP/2 multiplexed streams can
suffer HoL blocking primarily due to HTTP/2's layering above TCP.
However if HPACK is used for header compression, HTTP over QUIC is
still vulnerable to HoL blocking, because of how HPACK exploits
header redundancies between multiplexed HTTP transactions. This
draft defines QCRAM, a variation of HPACK and mechanisms in the QUIC
HTTP mapping that allow QUIC implementations the flexibility to avoid
header-compression induced HoL blocking.
Please note that it may take a couple of minutes from the time of submission
until the htmlized version and diff are available at tools.ietf.org.
