Abstract:
1. A method comprising: passing packets between first and second wireless mesh networks, at least in part via first and second mesh bridge nodes respectively associated with the first and the second wireless mesh networks, to form a multi-mesh network; accumulating route cost information at least in part during the packet passing, the accumulating being performed at least in part via the mesh bridge nodes, the accumulated route cost information corresponding to cost of forwarding a respective packet through each wireless mesh network the respective packet has traversed up to when the accumulated route cost information is updated, the accumulating route cost information comprising stripping route cost information specific to a just-traversed wireless mesh network from the respective packet and appending to the respective packet respective route cost information for the just-traversed wireless mesh network; and forwarding at least some of the packets, at least in part via the mesh bridge nodes, according to efficient routes based at least in part on the accumulated route cost information.
