This document describes how to schedule traffic from CTCC, CUCC, and CMCC through smart scheduling.
With a CTCC/CUCC/CMCC Anti-DDoS Advanced instance, business traffic can be forwarded according to the source ISP of DNS requests, which is a common traffic scheduling method. You can configure smart scheduling to schedule the traffic from CTCC, CUCC, CMCC, or other ISPs to the Anti-DDoS Advanced instances of CTCC, CUCC, CMCC, and other ISPs respectively.
- Before enabling smart scheduling, please connect your business to your Anti-DDoS instance.
- If you need to add the IP of your protected Tencent Cloud product to an Anti-DDoS Pro instance, please see Getting Started.
- If you need to connect your layer-4 or layer-7 business to an Anti-DDoS Advanced instance, please see Anti-DDoS Advanced documents Port Connection or Domain Name Connection.
- To modify the DNS resolution, you need to purchase a domain name resolution product.
- Log in to the Anti-DDoS console, select Anti-DDoS Advanced (New) -> Smart Scheduling on the left sidebar to view the policy list, and click New Scheduling Policy to automatically generate a CNAME record.
- Click Add Anti-DDoS instance of the CNAME record to enter the smart scheduling editing page.
- The TTL value defaults to 60 seconds and ranges from 1 to 3,600 seconds. The default scheduling mode is Priority.
- Click Add Anti-DDoS IP, tick the target Anti-DDoS instance and IP, and click OK.
- After the instance is selected, DNS will be enabled for its protective line by default. At this point, you can set the line priority.
- The priority of the three ISPs must be the same to guarantee that DNS requests can receive responses according to source ISPs.
- For smart scheduling configurations, please see Configuring Smart Scheduling.
