Route Refresh Time
—Once a route has been established, periodic route updates are
broadcast to the wireless network. The
Route Refresh Time function
determines how
frequently route update messages are broadcast. If the
Route Refresh Time
setting
is too short, then there may be excessive overhead on the radio network in carrying
the route updates. If the
Route Refresh Time
setting is too long, then the network
may be slow to optimize routes when better routes become available (e.g. when a new
repeater is added or when temporary interference abates). The recommended value is
180 minutes.
•
LLP Timeout
—SpeedNet Radios normally attempts to find the path between nodes that
has the fewest number of hops. However, sometimes the shortest path is not always the
optimal one because of conditions such as RF interference, line-of-sight impediments,
multipath propagation, and network congestion. If the
Local Link Preference
setting is
enabled and a radio experiences an inability to deliver messages through a given
neighboring node, SpeedNet Radios will attempt to avoid that neighbor if alternate
neighbors are available to deliver the messages.
LLP can co-exist with the
Blacklisting f
eature introduced in SpeedNet Revision
2.4.7. Radios can be added to the blacklist and not used for routes. With LLP on these
neighbors won’t be used and LLP will search for alternate routes if the radio is unable
to deliver messages through a neighboring mode.
The LLP Timeout parameter specifies when a neighbor who had been put in the LLP
blacklist, is made available as a routing option. Setting the
LLP Timeout
function to 0
effectively disables LLP. When LLP is enabled, the recommended value for LLP Timeout is
1440 minutes (1 day).
