boost :: asio将binary_iarchive发送给多个客户端？

Question

我正在使用boost::asio::ip::tcp::iostream和序列化通过tcp发送自定义结构。

我的代码是：

//服务器

    while (!_exit)
        {
            boost::asio::io_service ios;
            boost::asio::ip::tcp::endpoint endpoint
                = boost::asio::ip::tcp::endpoint(boost::asio::ip::tcp::v4(), 4444);
            boost::asio::ip::tcp::acceptor acceptor(ios, endpoint);
            boost::asio::ip::tcp::iostream stream;

            // program stops here until client connects.
            acceptor.accept(*stream.rdbuf());

            connected = true;


            while (connected == true)
            {       
               try
            {
                boost::archive::binary_oarchive archive(stream);
                archive << data_out;

            }
                    catch (...) {

                        connected = false;
                    }
    }
}

//客户端

while (ShutdownRequested == false)
    {
        do {

            std::cout << "looking for connection..." << std::endl;
            stream.clear();

            stream.connect(ipline, portNum);

            std::this_thread::sleep_for(std::chrono::milliseconds(200));
        } while (!stream && ShutdownRequested == false);

        bConnected = true;

        while (bConnected == true && ShutdownRequested == false)
        {
            try
            {
                boost::archive::binary_iarchive archive(stream);
                archive >> data_in;
             catch (...) {

                bConnected = false;
            }

这很好用，但是我想扩展它，以便多个客户端可以同时连接。现在，第二个尝试访问的客户端被卡在"looking for connection..."上。

如何通过多个连接使它工作？
