Le consortium W3C a pr\u00e9sent\u00e9 la premi\u00e8re \u00e9bauche de la sp\u00e9cification WebTransport, qui d\u00e9finit le protocole et l'API JavaScript associ\u00e9e pour l'envoi et la r\u00e9ception de donn\u00e9es entre le navigateur et le serveur. Le canal de communication est \u00e9tabli au-dessus de HTTP\/3 en utilisant le protocole QUIC comme mode de transport, qui, \u00e0 son tour, est une couche au-dessus du protocole UDP, prenant en charge le multiplexage de plusieurs connexions et fournissant des m\u00e9thodes de cryptage \u00e9quivalentes \u00e0 celles de TLS\/SSL. <\/p>\n

WebTransport peut \u00eatre utilis\u00e9 comme alternative au m\u00e9canisme WebSockets, offrant des fonctionnalit\u00e9s suppl\u00e9mentaires telles que l'organisation du transfert en plusieurs flux, des flux unidirectionnels, la livraison sans tenir compte de l'ordre d'envoi des paquets (out-of-order), ainsi que des modes de livraison fiables et non fiables. De plus, WebTransport peut \u00eatre utilis\u00e9 \u00e0 la place du m\u00e9canisme Server Push, dont Google s'est retir\u00e9 dans Chrome.
