Latency Tuning

Considerations for using latency-related command options
There are several considerations for using these latency-related command options:
 Changing the options from their defaults may violate RFCs.
 Decrementing the values for these options increases the amount of network activity, for
example, there will be increased retransmissions.
 For a peer-to-peer application, you need to consider both sides of the connection and
how options are set. For example, if the setting for the rto_min option for the Digi
device is set to a value that is less than the setting for the delayed_ack option for the
other side of the connection, then there will be a forced retransmission of every packet
of data. For a master-slave application, this consideration does not apply.
Step 5: Optimize the application layer
Optimizing the application layer may include, but is not limited to, these recommendations:
 Avoid having more than one application/network node generating time-sensitive traffic
in the network Have one traffic generator in a master-slave setup on the network.
 Avoid running other (management) applications, such as email, image or mp3
downloading while time-sensitive traffic is running.
 Check whether the application itself has timers that cause retransmissions of data.
 Use firewalls.
