Abstract
A network interface of a first mesh point device, the network interface including a memory and a medium access controller. In response to the first mesh point device receiving a frame, the medium access controller determines whether a mesh path for routing the frame from the first mesh point device to a second mesh point device is stored in the memory. In response to a mesh path not being stored in the memory, and prior to performing a mesh path discovery protocol, the medium access controller (i) determines whether the second mesh point device is one hop from the first mesh point device, and if so selects a one hop path for routing the frame to the second mesh point device, otherwise (ii) uses the mesh path discovery protocol to determine a mesh path for routing the frame to the second mesh point device.
