Client-specific mesh paths to root access points in a mesh network
During operation, a mesh network access point (MAP) may communicate, via multiple mesh paths in a mesh network with the one or more root access points (RAPs), uplink packets or frames to or from at least two electronic devices. Notably, at a given time, the MAP uses a first mesh path in the mesh paths to communicate a first subset of the uplink packets or frames associated with a first electronic device in the two electronic devices and uses a second (different) mesh path in the mesh paths to communicate a second subset of the uplink packets or frames associated with a second electronic device in the two electronic devices. Moreover, the MAP may dynamically distribute the first electronic device or the second electronic device over the multiple mesh paths, e.g., based at least in part on one or more communication-performance metrics of the mesh paths and/or the mesh network.
