Abstract:
1. Method optimizing reliability of transmission of packets received in multicast mode from a first network to multicast transmission mode clients of a wireless second network, said method being implemented by a wireless access point device connecting said first network and said second network, said clients being directly connected to said wireless access point device through wireless connections and said packets originating from said first network being destined for clients of said second network, said method comprising the steps of: intercepting at least one subscription request to at least one multicast transmission group address, said at least one subscription request being sent to said first network by at least one of said clients of said second network, and transmission of said at least one subscription request to said first network; receiving from said first network, at least one multicast packet that is transmitted from said first network to said at least one multicast transmission group address; encapsulating at least a fragment of said at least one multicast packet transmitted from said first network into at least one unicast media control access layer packet; and, transmitting said at least one unicast media control access layer packet to each of said at least one of said clients of said second network that are subscribers to said multicast transmission group.
