MAC based mapping in IP based communications
First Claim
1. A method for Internet-Protocol based communications in a wireless network, the method comprising:
- receiving a series of multicast data packets, the series of multicast data packets corresponding to a video stream addressed to a group of one or more receiving nodes in a wireless network;
executing instructions stored in memory, wherein execution of the instructions by a processor converts the received series of multicast data packets into one or more unicast packets addressed to the one or more receiving nodes in the wireless network; and
wirelessly transmitting the one or more unicast data packets to the one or more receiving nodes using an 802.x protocol, wherein the effective unicast rate for the one or more unicast data packets exceeds a minimum data rate of the series of multicast data packets using the 802.x protocol.

Abstract
An access point of a communications network receives a multicast or broadcast packet from a source. The access point converts the multicast or broadcast packet into a unicast packet addressed to a station associated with the access point. The access point then transmits the unicast packet over the communications network from the access point to the station. The access point further may determine a minimum data rate by which the access point may transmit the multicast or broadcast packet to the station and determines an effective unicast rate for transmitting the unicast packet to the station. If the effective unicast rate does not exceed the minimum data rate, the access point does not transmit the unicast packet to the station and transmits the multicast or broadcast packet.
