AGGREGATING MULTIPLE WIRELESS CHANNELS

摘要

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.

主权项

1. A non-transitory machine readable medium having a set of instructions which, when executed by one or more hardware processors, causes performance of a set of operations comprising:
receiving, by a first device from a second device, data traffic over a particular wireless link of a plurality of wireless links that communicatively couple the first device and the second device, the data traffic indicating a particular MAC address as a source MAC address; storing, by the first device, an association between the particular wireless link and the particular MAC address; receiving, by the first device, a data packet to be transmitted to the particular MAC address; based on the stored association between the particular wireless link and the particular MAC address: selecting the particular wireless link, from the plurality of wireless links that communicatively couple the first device and the second device, to transmit the data packet to the second device; transmitting, by the first device to the second device, the data packet over the particular wireless link.
