Abstract
A method and apparatus for keeping information included in routing tables consistent throughout a wireless network are provided. The method includes enabling a mesh access point to generate data and transmit the data, gathering a plurality of pieces of information about a plurality of stations associated with the mesh access point, classifying the plurality of pieces of information into a plurality of blocks, generating a checksum for each of the blocks, and transmitting the checksum.

8. A method of keeping information included in routing tables consistent throughout a wireless network, the method comprising:
-
receiving checksum data corresponding to a block from a wireless network, the block comprising station information;
determining whether the received checksum data is identical to checksum data previously received;
if the received checksum data is not identical to the previously received checksum data, transmitting a request frame to an access point that previously sent the received checksum data requesting transmission of data of the block; and
receiving the data of the block from the access point and storing the received data in a routing table. - View Dependent Claims (9, 10, 11, 12)

13. A method of keeping information included in routing tables consistent throughout a wireless network, the method comprising:
-
receiving data of a block from a wireless network, the block comprising station information;
receiving checksum data corresponding to the block from the wireless network;
determining whether the data of the block has changed based on the received checksum data;
if the data of the block is determined to have changed, transmitting a request frame to an access point that previously generated and sent the original data of the block requesting the changed data of the block; and
receiving the changed data of the block from the access point and storing the received data in a routing table. - View Dependent Claims (14, 15, 16, 17, 18, 19)

20. An access point comprising:
-
a local association base (LAB) generation unit which gathers information about a plurality of stations associated with an access point and generates a LAB by classifying the information into a plurality of blocks;
a local association base checksum (LABC) generation unit which generates a LABC by generating checksum data for each of the blocks;
a hash unit which provides a hash function or a hash table necessary for generating the checksum data; and
a transmission unit which transmits the LAB or the LABC. - View Dependent Claims (21, 22, 23, 24)

25. A wireless network device comprising:
-
a reception unit which receives data of a block or checksum data corresponding to the block from a wireless network, the block comprising station information;
a global association base (GAB) generation unit which generates a GAB based on the received block data;
a hash unit which determines whether the received checksum data is identical to checksum data included in the generated GAB and corresponds to the block; and
a routing table which comprises station association information obtained by the GAB generation unit. - View Dependent Claims (26, 27, 28, 29)
