CDT Resource Plan - prepaid traffic package - Cloud Data Transfer

A CDT Resource Plan is a prepaid data transfer package that offsets CDT traffic at a lower cost with customizable specifications.

Product Overview

Features

Flexible specifications: Customize your plan size from 50 GB to 102400 GB in 1 GB increments.
Immediate activation, automatic offset: Once activated, the plan automatically offsets CDT traffic.
Lower costs: CDT Resource Plans generally offer lower unit prices than pay-as-you-go CDT billing.

For example, a customer used 1020 GB of CDT public BGP (multi-line) traffic in mainland China regions in June, with the first 20 GB covered by the free quota. Using pay-as-you-go CDT billing, the cost would be (1020 GB – 20 GB) × USD 0.118/GB = USD 118. The official discounted price for a 1000 GB CDT Resource Plan (Mainland China General) is USD 108.56, saving USD 9.44.
Fully compatible with tiered pricing: Offsets all CDT public traffic tiers beyond the free quota.

Purchase a CDT Resource Plan

Before purchasing, confirm in the CDT console that your products have been upgraded to CDT billing mode.

CDT provides a monthly free quota of 220 GB public traffic (20 GB/month for mainland China regions, 200 GB/month for regions outside the Chinese mainland), which offsets public traffic for ECS, Elastic IP Address, and Classic Load Balancer. Traffic beyond this quota uses tiered pricing.

If I have both CDT Resource Plans and General Data Transfer Plans, what is the offset order?
