This topic describes the billing of Anti-DDoS Premium instances of the Chinese Mainland Acceleration (CMA) mitigation plan.
An Anti-DDoS Premium instance of the CMA mitigation plan does not deliver protection capabilities. An Anti-DDoS Premium instance of the CMA mitigation plan must be used together with an Anti-DDoS Premium instance of the Insurance or Unlimited mitigation plan.
Overview
You can use an Anti-DDoS Premium instance of the CMA mitigation plan to reduce access latency for users in the Chinese mainland. If no attacks occur, an Anti-DDoS Premium instance of the CMA mitigation plan accelerates service delivery for users in the Chinese mainland. The CMA mitigation plan is offered in two versions: CMA and CMA 2.0.
CMA: If no attacks occur, an Anti-DDoS Premium instance of the CMA mitigation plan can use up to 100 Mbit/s of bandwidth to process service traffic.
CMA 2.0: If no attacks occur, an Anti-DDoS Premium instance of the CMA 2.0 mitigation plan can use up to 2 Gbit/s of bandwidth to process service traffic.
