Abstract

A premises based wireless network having a multi-segment wired network and a plurality of wireless access points connected to the wired network. The wired network operates according to a wired network protocol which may be the Internet Protocol. Wireless terminals communicate with the wireless access points according to a wireless network protocol. Communications occur on the wired network according to the wired network protocol. Each of the wireless terminals has a wired network address corresponding to one of the wireless access points. The protocol tunnels route communications intended for roaming devices between access points, thereby preserving communications while roaming by allowing the wireless terminals to retain their wired network addresses during ongoing communications. An address resolution packet proxy server presents flooding of the wireless network with address resolution packets. The address resolution packet proxy server may act as a full proxy for wireless terminals connected to a respective wireless access point thereby relieving the wireless terminal from responding to address resolution packet requests. The address resolution packet server may also operate as a partial proxy, filtering requests sent to corresponding wireless terminals. An augmenting agent provides enhanced services within a wireless network device by enhancing operation of drivers and protocol operators. The augmenting agent may be either a shim or monitoring agent that monitors communications between the protocol operator and the drivers. When required, the augmenting agent participates to alter operations to provide enhanced services. The enhanced services include encypherment/encryption, device authentication, global network configuration, diagnostics such as loop-back testing, signal strength feedback, wireless retry counts, network route tracing, network management, solving out-of-sequence packet race conditions and filtering and flooding restriction operation.

Claims

1. A premises based wireless network providing wireless communication within a premises, the wireless network comprising:

a wired network operating according to a wired network protocol, the wired network having a first network segment and a second network segment;

a first wireless access point connected to the first network segment;

a second wireless access point connected to the second network segment;

a wireless terminal having a wired network protocol address respective to the first wireless access point; and

a protocol tunnel that routes communications from the first wireless access point to the second wireless access point across the wired network when the wireless terminal is in communication with the second wireless access point.

2. The premises based wireless network of claim 1, the wired network operating according to an Internet Protocol.

3. The premises based wireless network of claim 1, wherein the first wireless access point originates the protocol tunnel.

4. The premises based wireless network of claim 1, wherein the second wireless access point originates the protocol tunnel.

5. The premises based wireless network of claim 1, further comprising a router that couples the first network segment to the second network segment.

6. The premises based wireless network of claim 1, wherein the first network segment and the second network segment have different subnetwork addresses.

7. The premises based wireless network of any of claim 1, further comprising

a third access point connected to the second network segment;

and

the protocol tunnel routing communications from the first wireless access point to both the second wireless access point and the third access point across the wired network when the wireless terminal is not in communication with the first wireless access point.

8. The premises based wireless network of claim 1, wherein communications through the protocol tunnel are limited based upon communication type.

9. The premises based wireless network of claim 1, wherein address resolution packets are selectively passed through the protocol tunnel.

10. The premises based wireless network of claim 1, wherein communications through the protocol tunnel are reordered upon receipt based upon an original ordering.

11. A premises based wireless network providing wireless communication within a premises, the wireless network comprising:

a wired network operating according to a wired network protocol;

a plurality of wireless access points connected to the wired network;

a plurality of wireless terminals operating within the premises, each of the plurality of wireless terminals in communication with at least one access point of the plurality of access points; and

at least one of the plurality of wireless access points including a proxy address resolution packet server that responds to address resolution packets for at least one of the wireless terminals.

12. The premises based wireless network of claim 11, wherein the proxy address resolution packet server comprises:

an address resolution packet database that contains entries for wireless terminals connected to a respective wireless access point.

13. The premises based wireless network of claim 11, wherein:

the wired network comprises a first subnetwork and a second subnetwork;

the proxy address resolution packet server resident in an access point coupled to the first subnetwork discards address resolution packets having source or target addresses respective to the second subnetwork.

14. The premises based wireless network of claim 11, wherein

a wireless terminal registers with the proxy address resolution packet server when it attaches to a respective wireless access point.

15. The premises based wireless network of claim 11, wherein
