    It's important that you understand the connection-oriented portion of the Transport layer. Before a transmitting host starts to send segments down the model, the sender's TCP process contacts the destination's TCP process to establish a connection. What is created is known as a__________ _________.
  • 17. 
    ______ _________ provides a means for the receiver to govern the amount of data sent by the sender.  It prevents a sending host on one side of the connection from overflowing the buffers in the receiving host — an event that can result in lost data.
  • 18.
