How to Fill in the Weight in the Origin Server Group?
When a weight is set for an origin server in the origin server group, all other origin servers must also have weights set. The weight can be an integer from 0 to 100. It is not supported to set weights for only some origin servers.
How Does It Work When an Origin Server in the Origin Server Group Has a Weight of 0?
When you set the weight of an origin server in the origin server group to 0, no traffic will be directed to that origin server. EO will route traffic back to other origin servers based on their weighted proportion out of 100.
How Does the Back-to-Origin Logic Work When Different Weights Are Configured for Multiple Origin Servers in the Origin Server Group and Intelligent Acceleration Is Enabled for the Corresponding Domain Name?
When using the combination of Smart Acceleration and origin server group weights, the following logic will apply: |
Configure Weights for Multiple Origin Servers in the Origin Server Group and Enable Intelligent Acceleration for the Corresponding Domain Name | Prioritize selecting the origin server based on weight, then Smart Acceleration will optimize the return link. |
Configure Weights for Multiple Origin Servers in the Origin Server Group without Enabling Intelligent Acceleration for the Corresponding Domain Name | Origin-pull by weight ratio. |
Multiple origin servers in the origin server group without configuring weights, enable intelligent acceleration for the corresponding domain name | Origin-pull from the optimal origin server selected by Smart Acceleration. |
Multiple origin servers in the origin server group without configuring weights, do not enable intelligent acceleration for the corresponding domain name | Poll each origin server in the origin server group, proportional origin return. |
What is the impact on existing connections when changing the origin server group configuration?
When you adjust the weight of an origin server in the origin server group from a value greater than 0 to 0 or directly delete an origin server, existing established return connections will not be affected. New connections will not be forwarded to the origin server with a weight of 0 or the deleted origin server.
What are the IP range restrictions when using IP as an origin address?
IPv4 address: 0.0.0.0/8, 9.0.0.0/8, 10.0.0.0/8, 11.0.0.0/8, 30.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16, 127.0.0.0/8, 255.255.255.255
IPv6 address: fe80::/10, fc00::/7, ::1, ::
The above subnet ranges are not allowed to be used as EdgeOne origin IPs. If you have any questions, please contact us. How to Configure Origin SNI
The origin SNI is set to be the same as the current origin Host by default and cannot be modified in the console.
