196  * after changing the network size.
197  *
198  * It is recommended to set the correct network size because some Wi-SUN network configuration parameters are
199  * adjusted based on the selected network size. A network configured for a small amount of devices may not work
200  * optimally for large number of devices. This is because the network bandwidth is divided with all the devices in
201  * the network. Enough bandwidth must be reserved for application data usage as well as the Wi-SUN network
202  * operations. In addition, the application should adapt to the network characteristics by using the InternetSocket
203  * methods get_stagger_estimate_to_address() and get_rtt_estimate_to_address().
204  *
205  * The network size is measured as hundreds of devices that are expected to join to the network. For example,
206  * for a 400-device network set network size to 4.
207  *
208  * The Wi-SUN stack will automatically adjust timing and RPL configuration values based on the selected network
209  * size and data rate. If a customized timing or RPL values are needed, the APIs below should be invoked after
210  * changing the network size:
211  * - set_timing_parameters() to set timing settings to the Wi-SUN interface.
212  * - rpl_parameters_set() to set RPL settings to the Border Router interface.
213  *
214  * By default the Wi-SUN stack is configured to use a few hundreds of devices.
215  *
216  * The network size should be set to 0 when running certification tests.
