It supports two scheduling algorithms: weighted polling and weighted minimum connections.

• Weighted polling

The request is allocated according to the weight value set by the backend server. The higher the weight value, the more times it is allocated.

• Weighted minimum connections

In addition to the weight value to allocate requests, the number of connections to the back-end server is also considered. When the weight value is the same, the backend server with the smaller number of current connections will be assigned to the request.
