Abstract

An apparatus comprising An input circuit to receive packets of data from a network, A memory stores packet filter criteria for one or more wireless clients, A filter circuit selects one or more of the packets of data according to the packet filter criteria, A packet circuit prepares one or more reply packets for each of the packets of data that are selected by the filter circuit, An output circuit transmits the reply packets to the network.

Claims

1. An apparatus in communication with each of a network and one or more wireless clients, the apparatus comprising:

a wireless input circuit configured to receive a wireless signal from a first wireless client of the one or more wireless clients, the wireless signal representing a command from the first wireless client;

a packet circuit configured to generate each of a plurality of reply packets according to the command received from the first wireless client; and

an output circuit configured to periodically transmit, on behalf of the first wireless client, each of the plurality of reply packets to the network in response to the command.

2. The apparatus of claim 1, further comprising:

an input circuit configured to receive one or more packets of data from the network; and

a wireless output circuit configured to respectively transmit the one or more packets of data to the one or more wireless clients.

3. The apparatus of claim 1, wherein each of the plurality of packets comprises:

an Internet Group Messaging Protocol (IGMP) join packet.

4. A method for generating and transmitting a plurality of packets on behalf of a wireless client, the method comprising:

receiving a wireless signal from the wireless client, the wireless signal representing a command from the wireless client;

generating each of a plurality of reply packets according to the command from the wireless client; and

periodically transmitting, on behalf of the wireless client, each of the plurality of reply packets to a network in response to the command.

5. The method of claim 4, wherein each of the plurality of packets comprises:

an Internet Group Messaging Protocol (IGMP) join packet.

6. A tangible non-transitory computer readable medium storing a computer program executable on a processor, the computer program comprising instructions for:

receiving a wireless signal from a wireless client, the wireless signal representing a command from the wireless client;

generating each of a plurality of reply packets according to the command from the wireless client; and

causing an output circuit to periodically transmit, on behalf of the wireless client, each of the plurality of reply packets to a network in response to the command.

7. The tangible non-transitory computer readable medium of claim 6, wherein each of the plurality of packets comprises:

an Internet Group Messaging Protocol (IGMP) join packet.
