  • the present invention relates to the field of wireless network technologies, and in particular, to a method and apparatus for setting a transmission rate in a multicast/broadcast technology.
  • Unicast, broadcast, and multicast are three types of communication that transmit data based on the TCP/IP protocol.
  • Unicast means that a separate information forwarding path is established between the sender and each receiver. There is a "one-to-one" communication mode between the sender and the receiver. The switches and routers in the network only forward the data. To make a copy, for example, if 10 recipients need the same data, the sender needs to transmit one by one and repeat the same work 10 times.
  • Broadcasting means that the transmitting end broadcasts data packets throughout the network. It is a "one-to-one" communication mode. All hosts in the entire network can receive data packets, which is beneficial to the full utilization of network resources.
  • Multicast is a network technology that allows one or more senders (multicast sources) to send a single packet to multiple recipients.
  • the multicast source sends the data packet to a specific multicast group, and only the receivers belonging to the multicast group address can receive the data packet.
  • IP multicast communication no matter how many target addresses, any one of the entire network Only a single packet is transmitted on the link, which greatly saves network bandwidth.
  • the unicast communication method can respond to the request of the target user in time, the server needs to send a data stream for each user, and the server is heavily burdened, which is likely to cause the network backbone to be overwhelmed and form a network congestion. Therefore, many applications in the network system use multicast and broadcast protocols, such as service discovery, dynamic address acquisition, and the like. At the same time, with the widespread use of wifi, video broadcasting over WLANs in wireless local area networks has become very attractive, especially in high-density environments for users such as stadiums. Multicast and broadcast communication provides a more efficient and efficient way to transfer data.

  • the existing multicast/broadcast service uses a fixed basic rate to transmit data. When the signal quality between the receiver and the sender changes, the transmission rate between the sender and the receiver cannot be adjusted in real time, which is prone to occur. A high transmission error causes the wireless client to fail to receive multicast packets correctly.

Le procédé de réglage d'un débit d'envoi dans une technologie de diffusion sélective/non sélective comprend : la surveillance si un débit optimal d'unidiffusion d'un utilisateur cible en diffusion sélective/non sélective est mis à jour ; la mise à jour, s'il en est ainsi, d'un ensemble de débits optimaux de la diffusion sélective/non sélective, l'ensemble de débits optimaux comprenant des débits optimaux de transmission d'unidiffusion de tous les utilisateurs cibles en diffusion sélective/non sélective ; la sélection d'une valeur minimale d'un débit de transmission parmi l'ensemble de débits optimaux ; et le réglage, selon la valeur minimale du débit de transmission, d'un débit d'envoi de diffusion sélective/non sélective. Le procédé et l'appareil de réglage d'un débit d'envoi dans une technologie de diffusion sélective/non sélective de la présente invention peut ajuster dynamiquement un débit d'envoi de données dans un service de diffusion sélective/non sélective et améliorer les performance d'envoi en diffusion sélective/non sélective.
