| Cloud Interconnection Bandwidth Package | It is the chargeable item for cloud interconnectivity. The bandwidth set at the time of purchase is the maximum bandwidth limit, and the bandwidth set in this package can be freely allocated by the user to subordinate virtual channels. The total bandwidth of subordinate virtual channels cannot exceed the bandwidth value of this package. | Free up to 2Gbps, exceeding 2Gbps requires contacting technical support for an upgrade, incurring corresponding fees. | **When users choose the primary-backup scenario, since the two bandwidths in the primary-backup scenario must be of the same size, the fee charged will be twice the bandwidth package value filled in (free within 2G)**; for load scenarios, it is the bandwidth package value filled in. |
| Virtual Channel    | Corresponding virtual channel bound to the shared virtual port                                                                          | /                                                            | Currently in free trial, free duration of 6 months                                                                                  |
