SpeedNet Client Tool

IP Routing Window,

Ad Hoc Routing Tab

Figure 71. The Ad Hoc Routing IP configuration window.

The 

IP Routing

 window provides a list of tabs that can be used to confi gure the routing 

performance of a SpeedNet Radio. Selecting a tab will provide a list of confi gurable options.

The 

Ad Hoc Routing 

tab, shown in Figure 71, is used to enable, disable, or configure 

the embedded ad hoc (mesh) routing protocol. The embedded ad hoc routing protocol 
is a customized version of Ad-hoc On-demand Distance Vector (AODV). The following 
parameters can be configured:

•  Off

—Selecting 

Off

 will disable the automated mesh networking protocol. When

disabled, static routes must be entered manually on the 

Routes

 tab for all endpoints 

this radio needs to reach. No combination of automatic AODV routing and static 
routing is supported

•  AODV

—Selecting 

AODV

 will enable the embedded mesh networking protocol

allowing network routes to be created and maintained automatically to the best 
next hop neighbor from the SpeedNet Radio. All radios in the network must enable 
AODV to use the feature. Selecting 

AODV

 is recommended for ease of confi guration,

robustness to radios going down, and ease of adding radios to the mesh. The
remaining confi guration options on the 

Ad Hoc Routing

 tab pertain specifi cally to 

the mesh networking protocol

•  Active Route Timeout

—The 

Active Route Timeout

 parameter determines how 

long a SpeedNet Radio should wait for an inactive data communication route to be 
removed from the route table. Each time an IP packet is sent over a specifi c route, a 
timer begins counting down. If the timer expires before another packet is sent, the route 
is considered inactive and is removed from the radio’s route table. The 

Active Rout

e 

Timeout

 value determines the length of this timer. In SCADA polling applications, a 

timeout value greater than the polling interval is recommended. Note that a route is 
defi ned by the IP address of the two endpoints. A given pair of SpeedNet Radios may 
have several separate routes between them, for example serving different devices on 
the radios’ Ethernet ports. As such, activity on one route between two radios does 
not preserve other routes between the two radios for traffi c with different source/
destination IP addresses. The value of this parameter is measured in minutes and the 
recommended value is 30 minutes
