It is possible to select your ad server partners.
Publishers wishing to register their inventory to Broadsign Reach must contact Support. A Support representative will walk you through our Master Service Agreement. Once signed, we will proceed with adding your inventory to Broadsign Reach.
The ad serving partners with which you have an agreement are displayed in Splash > Configuration > Player Configuration, under the Ad Server Configurations tab. For example, if you have an agreement only with Broadsign Reach, only this ad serving partner is displayed. If you do not have any agreement with Broadsign Reach, no partner is displayed.
You can edit ad serving partners by clicking the 
button beside each of them.
You can enable one, both, or none.
If you enable both ad serving partners, you can prioritize one over the other.
When prioritizing: if the first ad server has nothing to offer, then Splash will go to the second ad server. If this ad server has nothing to offer, Splash will skip this slot in the loop.
It is not necessary to restart the player once ad serving has been enabled but it can be good opportunity to do so.
Splash has an exponential throttle on all ad serving connections. In the event of two consecutive unfilled ad requests, there is a throttle of two seconds. If the next call (in two seconds) is unfilled, the next call will be in four seconds. The throttle duration increases exponentially up to a maximum of two minutes. As soon as an ad request is filled, the throttle is disengaged entirely and the fill is evaluated using the above logic.
If you are observing requests at two-minute intervals, it means that the inventory offered is not being bought. However, the frequency will increase once a buyer is bidding on it. The purpose of the dynamic throttle is to find the balance between surfacing sufficient buying opportunities and not wasting bandwidth and processing resources for everyone in the programmatic chain (including on your network).
