Distributed access point for IP based communications
First Claim
1. An apparatus for Internet-Protocol based communications in a wireless network having a minimum available physical data rate, the apparatus comprising:
- a network interface to receive a plurality of multicast data packets;
a memory; and
a processor for executing instructions stored in the memory to;
identify a plurality of receiving nodes in the wireless network requesting data corresponding to the plurality of multicast data packets,convert the received plurality of multicast data packets into one or more unicast data packets,determine an effective unicast rate for said one or more unicast data packets, wherein the effective unicast rate corresponds to a combined rate for converting the plurality of multicast packets into one or more unicast packets and sending the one or more unicast packets to the receiving nodes,compare said effective unicast rate to said minimum available physical data rate,serially transmit said one or more unicast data packets, via the network interface, to said plurality of receiving nodes at said effective unicast rate, when said effective unicast rate is greater than said minimum available physical data rate, andserially transmit said one or more unicast data packets, via the network interface, to said plurality of receiving nodes at said minimum available physical data rate, when said effective unicast rate is less than or equal to said minimum available physical data rate, wherein said network interface is capable of transmitting and receiving both multicast data packets and unicast data packets.

Abstract
An apparatus for Internet-Protocol based communications in a wireless network includes a network interface, a controller, and memory. The interface receives a series of multicast data packets. The controller identifies one or more receiving nodes in the wireless network requesting data corresponding to the series of multicast data packets and determines that the effective unicast rate for one or more unicast data packets exceeds a minimum data rate of the series of multicast data packets using an 802.x protocol. The memory stores instructions that may be executable by a processor. Upon execution of the instructions by a processor, the received series of multicast data packets is converted into one or more unicast packets, the execution and conversion occurring in response to instructions received from the controller. A system for Internet-Protocol based communications in a wireless network implements such an apparatus in the context of an access point.
