Another function of the transport layer is to provide optional flow control Flow control is used to ensure that networking components don t send too much information to the destination, overflowing its receiving buffer space and causing it to drop some of the transmitted information Overflow is not good because the source will have to resend all the information that was dropped The transport layer can use two basic flow control methods:

Ready/Not Ready Signals With ready/not ready signals, when the destination receives more traffic than it can handle, it can send a not ready signal to the source, indicating that the source should stop transmitting data When the destination has a chance to catch up and process the source s data, the destination responds back to the source with a ready signal Upon receiving the ready signal, the source can resume sending data Two problems are associated with the use of ready/not ready signals to implement flow control First, the destination may respond to the source with a not ready signal when its buffer fills up While this message is on its way to the source, the source is still sending information to the destination, which the destination will probably have to drop because its buffer space is full The second problem with the use of these signals is that once the destination is ready to receive more information, it must first

send a ready signal to the source, which must receive it before more information can be sent This causes a delay in the transfer of information Because of these two inefficiencies with ready/not ready signals, they are not commonly used to implement flow control Sometimes this process is referred to as stop/start, where you stop transmitting for a period and then start retransmitting
Windowing Windowing is a much more sophisticated method of flow control than using ready/not ready signals With windowing, a window size is defined that specifies how much data (commonly called segments at the transport layer) can be sent before the source has to wait for an acknowledgment (ACK) from the destination Once the ACK is received, the source can send the next batch of data (up to the maximum defined in the window size) Windowing accomplishes two things: First, flow control is enforced, based on the window size In many protocol implementations, the window size is dynamically negotiated up front and can be renegotiated during the lifetime of the connection This ensures that the most optimal window size is used to send data without having the destination drop anything Second, through the windowing process, the destination tells the source what was received This indicates to the source whether any data was lost along the way to the destination and allows the source to resend any missing information This provides reliability for a connection as well as better efficiency than ready/not ready signals Because of these advantages, most connection-oriented transport protocols, such as TCP/IP s TCP, use windowing to implement flow control The window size chosen for a connection impacts its efficiency and throughput in defining how many segments (or bytes) can be sent before the source has to wait for an ACK Figure 2-2 illustrates the importance of the size used for the window The top part of the figure shows the connection using a window size of 1 In this instance, the source sends one segment with a sequence number (in this case 1) and then waits for an acknowledgment from the destination Depending on the transport protocol, the destination can send the ACK in different ways: it can send back a list of the sequence numbers of the segments it received, or it can send back the sequence number of the next segment it expects The ACK from the destination has a number 2 in it This tells the source that it can go ahead and send segment 2 Again, when the destination receives this segment, since the window size is 1, the destination will immediately reply with an acknowledgment, indicating the receipt of this segment In this example, the destination acknowledges back 3, indicating that segment 3 can be sent, and so on and so forth
