Title

(EN) METHOD AND SYSTEM FOR DATA TRANSMISSION WITH SIGNIFICANTLY REDUCED LATENCY LOSSES

(FR) PROCÉDÉ ET SYSTÈME DE TRANSMISSION DE DONNÉES AVEC DES PERTES DE LATENCE SIGNIFICATIVEMENT RÉDUITES

Abstract

(EN) Data transmission delays can be significantly reduced by a method comprising by a client computer 10,receiving a command for downloading distributed information 80 being identified by a primary location on a server 30a – 30e sending information about the primary location to a proxy server 20, and retrieving at a primary piece of information 81 of the distributed information 80 being wherein the primary piece of information 81 includes instructions for obtaining secondary pieces of information 82a-82c each being identified by secondary locations and determining a sequence of importance 5 of the secondary pieces of information 82a – 82c. The proxy server as well determines the sequence of importance 5 and sends a first data stream 41 comprising at least a portion of the secondary pieces of information 82a – c to the client computer according to the sequence

(FR) Des retards de transmission de données peuvent être significativement réduits par un procédé comprenant par un ordinateur client 10, la réception d'une commande de téléchargement vers l'aval d'informations distribuées 80 identifiées par un emplacement primaire sur un serveur 30a – 30e, l'envoi des informations concernant l'emplacement primaire à un serveur mandataire 20, et la récupération au niveau d'un élément d'informations primaire 81 des informations distribuées 80, l'élément d'informations primaire 81 comprenant des instructions pour obtenir des éléments d'informations secondaires 82a -82 c, chacun étant identifié par des emplacements secondaires et par détermination d'une séquence d'importance 5 des éléments d'informations secondaires 82a-82c. Le serveur mandataire détermine ainsi la séquence d'importance 5 et envoie un premier flux de données 41 comprenant au moins une partie des éléments d'informations secondaires 82a-c à l'ordinateur client selon la séquence
