我能在TCP/IP数据包发送之前得到它吗?

在同一台机器上运行一个客户机和一个服务器应用程序。它们与TcpClient和tcpplistener使用异步通信。

服务器应用程序在后台工作线程中执行一些数据处理。每次处理每个数据部分时，如果有任何客户端连接到它并已发送请求以获取已处理的数据部分，则尝试使用TcpListener发送它。

在BeginWrite函数调用后，服务器立即设置客户端标志以避免发送新数据，直到客户端发送另一个请求。当请求到达TcpClientDataReadAsyncCallback()时，一个标志被设置为客户端，以便后台工作器可以向该客户端发送数据

这是服务器和客户端的日志

00.37.41.412 client timed out RX operation

00.37.35.772是hh:mm:ss:ms

634538758557701309行尾的数字是请求/响应对象的时间戳，以便在日志中整理它们

正如您所看到的，一切都在适当的时候运行，直到191229字节的对象在发送之前到达。客户端在收到响应之前不发送新的请求。我不明白这怎么可能。
