Where 9113 fits
Why 9113 is special
Multiplexing many streams over one connection removed head-of-line blocking at the HTTP layer and left it at the TCP layer, which is what HTTP/3 then addressed.
Not just a mathematical number
9113is also used in ways where ordinary arithmetic doesn't apply — each listed below with what genuinely does and doesn't follow from it.
- Mathematical number
A genuine quantity — its mathematical properties (prime, square, factors, and so on) are real facts about it.
A genuine quantity that ordinary arithmetic applies to — it can be prime, even, a perfect square, added to another number meaningfully, and so on.
- Code
Also used as a code — HTTP status codes.
An assigned identifier from a fixed registry or standard — its digits don't represent an amount, and arithmetic on it is meaningless (HTTP status 404 + 1 is not a 'better' status; it's a different, unrelated code).

Hexadecimal

2 × 4,096 + 3 × 256 + 9 × 16 + 9 × 1 = 9,113
Read as powers of two: 8,192 + 512 + 256 + 128 + 16 + 8 + 1 = 9,113.
In historical numeral systems
Egyptian
9 lotuses, 1 coil of rope, 1 hobble, 3 strokes
9 × 1,000 + 1 × 100 + 1 × 10 + 3 × 1 = 9,113. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Systems that simply cannot reach this value are left out. Where a script needs a font most readers do not have, the reading is given instead of the glyphs — see number systems for each system in full.

Related numbers & connections
HTTP/2 carries the same status codes over binary framing, with its own stream error codes alongside them.
RFC 9113 obsoletes RFC 7540 as the HTTP/2 specification within the restructured document set.
View 7540 →Technology & computing
RFC 9113 specifies HTTP/2 with binary framing, stream multiplexing and header compression. A single lost TCP segment still stalls all multiplexed streams, which QUIC resolves.
