Can an SDP be used across regions?

No. An SDP can be used only in the same region. If you need to use an SDP for EIPs in multiple regions, you need to subscribe to an SDP in each region.

When an SDP is purchased, how can I add EIPs to the deduction range of the SDP?

You do not need to perform any configuration. After you subscribe to an SDP, the traffic charge of all EIPs in the region is automatically deducted from the SDP.

When EIPs are added to the shared bandwidth and an SDP is purchased, how are the EIPs charged?

After an SDP and EIPs that are added to the shared bandwidth are purchased at the same time, the bandwidth charge is deducted first from the shared bandwidth rather than the SDP. If you hope to use the SDP, remove the EIPs from the shared bandwidth.

If some EIPs in a region want to be charged by traffic separately, can the traffic charge of the EIPs not be deducted from the SDP?

For the EIPs that are charged by traffic in a region where an SDP is purchased and are not added to the shared bandwidth, the traffic charge is deducted from the SDP with no separate billing available. In the current version, EIPs can be added to and billed from the shared bandwidth.

Will the network service be stopped after an SDP is used up?

No. After an SDP is used up, the traffic charge generated by EIPs is charged according to the traffic billing rules.

If the capacity of a purchased SDP is insufficient, can I expand the capacity?

An SDP does not support change of the configuration. If the capacity of an SDP is insufficient, you can buy a new SDP.

When multiple SDPs are purchased, what is the order of the SDPs for use?

The traffic charge is deducted from SDPs in an order whichever is expired earlier. The order cannot be adjusted.

If there are multiple SDPs, how do I set a remaining reminder for the total remaining volume of all SDPs?

You do not need to configure a remaining reminder for the total amount of all SDPs. You can only enable the remaining reminder for the last SDP that expires.

After an SDP is purchased, why is the IP still charged?

For EIPs that are charged by traffic, the billing items include the traffic charge and the IP address retention fee (charged by hour). An SDP is used to deduct only the traffic charge generated by EIPs rather than the public IP address retention fee.
