US Patent 8705580 Aggregating multiple wireless channels

Extending wired networks by aggregating multiple wireless links. Multiple wireless links are used to bridge wired networks, such as wired Ethernet networks. Each wireless link applies a hash function to the destination MAC address of presented traffic and uses the result of the hash function to determine if the traffic is passed by that wireless link or is dropped. For broadcast and multicast frames, the hash function is calculated on the source MAC address. Dynamic source MAC rewriting may be performed to prevent port flapping or out-of-order arrival of frames. Establishing one link as a master and communicating among links allows for load balancing and link failure detection.
