A key advantage of the QUIC transport is stream -multiplexing free of head-of-line (HoL) blocking between streams. In HTTP/2, -multiplexed streams can suffer HoL blocking due to TCP. - -If HTTP/2's HPACK is used for header compression, HTTP/QUIC is still vulnerable -to HoL blocking, because of HPACK's assumption of in-order delivery. This draft -defines QCRAM, a variation of HPACK and mechanisms in the HTTP/QUIC mapping that -allow the flexibility to avoid header-compression-induced HoL blocking. +This specification defines QCRAM, a compression format for efficiently +representing HTTP header fields, to be used in HTTP over QUIC. This is a +variation of HPACK header compression that seeks to reduce head-of-line +blocking. --- middle
