An origin pool is a group of origin servers. You can assign different weights to origin servers and integrate the load balancing feature to configure flexible traffic steering policies.
Overview
DCDN can steer traffic among origin servers in a pool based on their weights. Origin pools can be referenced by DCDN-covered domains and TCP/UDP acceleration applications. By integrating origin pools with load balancing, you can flexibly and intelligently steer traffic to reduce origin strain and boost your service availability.
