scheduler

The scheduling algorithm. Valid values:

• Wrr: The weighted round-robin algorithm is used. Backend servers with higher weights receive more requests than backend servers with lower weights. This is the default value.

• rr: The round-robin algorithm is used. Requests are forwarded to backend servers in sequence.

• sch: Source IP hashing is used. Requests from the same source IP address are forwarded to the same backend server.

• tch: Four-element hashing is used. It specifies consistent hashing that is based on four factors: source IP address, destination IP address, source port, and destination port. Requests that contain the same information based on the four factors are forwarded to the same backend server.
