algorithm, added a program for collecting dynamic weights and fed back it to the Load balancer's scheduling system in real time. Practice has proved that the use of dynamic balancing has improved the overall throughput of the cluster system, especially when the performance of each node in the cluster is different and the network service programs provided by the cluster have diversified resources, the negat

if it fails, returns Invalid_socket. The first parameter of the function specifies a stream socket in the listening state; the operating system uses the second parameter to return the address structure of the newly created socket, and the operating system uses the third parameter to return the length of the address structure of the newly created socket. The following is an example of a call to accept:struct sockaddr_in serversocketaddr;int Addrlen;Addrlen=sizeof (SERVERSOCKETADDR);Serversocket=
