with the weighted polling method, the weighted stochastic method is also based on the configuration of the backend machine, and the load of the system is assigned different weights. The difference is that it is randomly requested by weight on the backend server, rather than in order.6. Minimum connection number methodThe minimum number of connections algorithm is more flexible and intelligent, because the configuration of the backend server is not the same, the processing of the request is fast
