Methods and systems for progressive synchronization in real-time of stored copies of media transmitted between nodes on a network. The methods and systems include progressively transmitting available indexed media from a sending node to a receiving node with a packet size and packetization interval sufficient to enable the near real-time rendering of the indexed media, wherein the near real-time rendering of the indexed media provides a recipient with an experience of reviewing the transmitted media live. At the receiving node, the transmitted indexed media is progressively receive and any indexed- media that is not already locally stored at the receiving node is noted. The methods and systems also include the real-time synchronization of the media of a conversation between two communication devices over the network by requesting missing media from the sending node. As voice or other media is created at either communication device, the copies of the media are synchronized in real-time across the network. The methods and systems also include optimized routing protocols that are simple to implement and decrease network traffic and latency.

La présente invention concerne des procédés et systèmes de synchronisation progressive en temps réel de copies stockées de supports transmises entre des nuds sur un réseau. Les procédés et systèmes comprennent la transmission progressive de supports indexés disponibles depuis un nud d'envoi vers un nud de réception avec une taille de paquets et un intervalle de groupage par paquets suffisants pour permettre le rendu en temps quasi réel des supports indexés, ce rendu en temps quasi réel des supports indexés apportant à un destinataire la possibilité de revoir en direct le support transmis. Sur le nud de réception, les supports indexés transmis sont progressivement reçus et tout support indexé qui n'est pas encore stocké localement sur le nud de réception est noté. Les procédés et systèmes comprennent également la synchronisation en temps réel des supports d'une conversation entre deux dispositifs de communication sur le réseau, qui implique de demander le support manquant au noeud d'envoi. Lorsque des données vocales ou d'autres supports sont créés par l'un des dispositifs de communication, les copies des supports sont synchronisées en temps réel sur le réseau. Les procédés et les systèmes comprennent également des protocoles de routage optimisés qui sont simples à mettre en uvre et qui diminuent le trafic et la latence du réseau.
