以替代方式使用多个插座通过C中的SCTP发送和RCV数据

Question

我正在使用SCTP编写C客户端服务器程序，因此在开始时，在客户端仅打开一个插座，用于发送和RECV，所有线程都使用。经过一定的条件后，我必须打开一个新的插座，现在我有两个插座，此时，两个插座都应通过所有线程以用于负载共享的所有线程来发送和接收。同样，随着插座的不增加，客户替代方案应将其用于负载共享。 有建议吗？使用选择，民意调查，普通插座等？

connSock = socket (AF_INET, SOCK_STREAM, IPPROTO_SCTP);
if (connSock == -1)
{
      perror("socket()");
      exit(1);
}

struct sctp_paddrparams params;
len = sizeof(params);

memset(&params, 0, sizeof(params));
if (getsockopt(connSock, IPPROTO_SCTP, SCTP_PEER_ADDR_PARAMS, &params, &len)) {
       perror("getsockopt");
       exit(1);
}
        
// set client address
struct sockaddr_in localaddr;
localaddr.sin_family = AF_INET;
char* client_ip = get_our_ip();
localaddr.sin_addr.s_addr = inet_addr(client_ip) ;
localaddr.sin_port = 0; 
bind(connSock, (struct sockaddr *)&localaddr, sizeof(localaddr));

// set server address
bzero ((void *) &servaddr, sizeof (servaddr));
servaddr.sin_family = AF_INET;
servaddr.sin_port = htons (port); 
servaddr.sin_addr.s_addr = inet_addr(server_ip); 

ret = connect(connSock, (struct sockaddr *) &servaddr, sizeof (servaddr)); 
if (ret == -1)
{
    perror("connect()");
    close(connSock);
    exit(1);
}

// ----> at this point only one socket is opened from client and all threads are using the same.

if(due_to_some_condition_got_new_server_ip){
// --> I have opened a new socket to connect to server_ip2. Now we 
// have 2 sockets opened, hence all threads should use sockets alternatively to send and receive data
