DTUS065 rev A.7 – June 27, 2014
Advanced mesh settings tab (only in 802.11s mode):
Path refresh time:
When data is sent through a previously discovered path which is due to
expire soon (i.e., in less than the “path refresh time” parameter), an early
discovery is started, so that the path will be already renewed when it should
have expired. This removes data latency due to expired path renewal.
“path refresh time” must be less than “active path timeout”.
Min discovery timeout:
When a path discovery request is sent, it will be resent if no response is
received after “min discovery timeout”. This discovery timeout is doubled
after each successive timeout for the same path. This value must be greater
than twice the “network diameter traversal time”, so that the timout covers
both a request and its response crossing the largest possible path in the
network.
Active path timeout:
This is the delay during which a path is considered valid, i.e. it can be kept
in cache tables and used before a renewal becomes mandatory. The target of
a path discovery inserts this value in its response to the requester. The
requester can use the path during this time at most, after which it must renew
the discovery (in case the target has moved).
Network diameter traversal time:
This is an estimate of the time needed for an HWMP frame to propagate
across the mesh.
Rssi threshold:
This is the threshold (in dBm) below which a plink will be closed if already
established or not allowed to start the peering process if not. Enter 0 to
disable this feature.
