request is sent, and then send the request to the server. Client-Based Load Balancing features: Implemented by the internal program of the client, without the need for additional hardware and software investment of the Server Load balancer. The program must solve the problem of Service Server unavailability, And the Server failure has little transparency to t

initiate the request to the server.Based on the characteristics of client load balancing: Implemented by the client internal program, no additional load balancer hardware and software inputs are required. Internal procedures need to address the issue of unavailability of the business Server, and server failures are less transparent to the applicatio
