Where 6455 fits
Why 6455 is special
Before it, live updates in a browser meant repeatedly asking the server whether anything had changed. WebSockets gave a two-way connection that stays open, which is what made live chat, collaborative editing and real-time dashboards ordinary.

6 × 1,000 + 4 × 100 + 5 × 10 + 5 × 1 = 6,455. 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.

WebSocket upgrades an HTTP connection to full duplex, which is why real-time browser applications stopped polling.
WebSockets originally upgraded a whole connection; over HTTP/2 a single stream is extended instead.

RFC 6455 defines WebSocket, which begins as an HTTP request and upgrades the connection to full-duplex. The upgrade mechanism has no HTTP/2 equivalent, which RFC 8441 later addressed.
DocumentedTechnology & computingGeography: International — IETFPeriod: 2011HTTP is request and response, so live updates meant polling. RFC 6455 in 2011 standardised a persistent two-way connection, and collaborative editing and live feeds became straightforward rather than ingenious.
