Abstract
The server side Transfer Control Protocol is modified so that the server returns a SYNACK message with the window size equal to zero if the server is busy. When a client sends a TCP connection request and receives a synchronization acknowledgement message with the window size equal to zero, the client knows that the server received the connection request and that the server is busy. The client may then send an acknowledgement message to complete the three-way synchronization handshake, thus successfully completing the connection. Thereafter, the client side TCP may probe the server side TCP until a window update message is received from the server. When the server sends a window update message to set the window size to a non-zero size, the client knows that the server is no longer busy and the client application may then use the TCP connection.
