Title:
ローカルエリアネットワークでマルチポイントストリームを伝送する方法及びその方法を実施する接続装置
Document Type and Number:
Japanese Patent JP4799008
Kind Code:
B2
Abstract:
Within the framework of a wireless local area network, the reliability of the transporting of the multicast streams is not enhanced by an acknowledgement of receipt mechanism. To improve this reliability the invention proposes a method of transporting packets transmitted in multicast mode by a device for connection between a first network and a second network, the multicast packets originating from the second network destined for clients of the first network, characterized in that it comprises a step of reception of multicast packets and the despatching according to a unicast transmission mode of at least certain packets transmitted in multicast mode to at least one of the clients of the first network that are subscribers to the transmission group.
