Load balancing

My project is based on client - server programming. Description: Multiple clients should connect to a main server. Main server will redirect to another sever which will respond to the client request. Once the request is redirected to another server there should be a direct connection between the server and the client without any involvement of the main server. once the client requested is completed the client should acknowledge the main server that the request is completed. +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Note: Before the main server redirects to another server. The main server should ping the server and wait for the sever to ping back. Once the sever pings back, the main server should establish a connection between the server and the client. Note 2: The main sever should distribute the clients to another servers in such a way that all the clients get equally distributed among the servers present under the main server.
