Title (EN) REAL TIME COMMUNICATION ADAPTIVE CONTROL METHOD
(FR) PROCEDE DE GESTION ADAPTATIVE DE COMMUNICATIONS EN TEMPS REEL
(JA) リアルタイム通信の適応制御方法
Abstract:
(EN) A real time communication adaptive control method capable of coping with a situation that a reception report packet transmitted to a distribution server from a device of the side receiving the data distribution is lost and realizing data distribution appropriate for a transmission path condition and a communication condition. According to this method, before starting transmission/reception of real time data, a reception report packet transmission interval is dynamically decided between a data distribution server (301) and a data reception device (101). After the real time data transmission/reception is started, the data distribution server (301) monitors the reception state of the reception report packet at the decided transmission interval as a unit and adaptively controls the data transmission rate and the like according to the monitoring result.
(FR) L'invention porte sur un procédé de gestion adaptative de communications en temps réel, pouvant faire face à des situations de perte de paquets de rapport de réception transmis à un serveur distributeur par un dispositif du côté recevant la distribution, et effectuant une distribution de données adaptée à l'état des voies de transmission et à l'état des communications. Selon ledit procédé avant de procéder à l'émission/réception de données en temps réel, on fixe dynamiquement l'intervalle de transmission des paquets de rapport de réception entre un serveur distributeur (301) et un dispositif de réception de données. Lorsque l'émission/réception en temps réel a commencé, le serveur distributeur (301) suit l'état de réception du paquet pour l'intervalle fixé, et gère adaptativement le débit de transmission et autres paramètres en fonction des résultats du suivi.
(JA) データ配信を受ける側の装置が配信サーバーに向けて送出する受信報告パケットが消失する事態に対して対策し、伝送路の条件や通信条件に適応した適切なデータ配信を実現することができる、リアルタイム通信の適応制御方法。本方法では、リアルタイムデータの送受信の開始前に、データ配信サーバー(301)とデータ受信装置(101)との間で、受信報告パケットの送出間隔の動的な取り決めを行う。そして、リアルタイムデータの送受信の開始後に、データ配信サーバー(301)が、取り決められた送出間隔を単位として受信報告パケットの受信状況を監視し、その監視結果に基づいて、データ送信レート等を適応的に制御する。
