Abstract
According to one embodiment of the invention, a method comprises an exchange of messages between an access point and a wireless network switch. One message, a PROXY IGMP JOIN message, is transmitted to the access point for propagation to a multicast router. This is performed so that multicast data associated with the multicast group identified by the PROXY IGMP JOIN message is routed to the access point without any unnecessary involvement by the wireless network switch.
