TCP Flow Control

• TCP inherently supports flow control to prevent buffer overflow at the receiver
  
  
  • Useful for fast sender transmitting to slower receiver
    
    
• Receiver advertises a window (wnd) in acknowledgements returned to the sender
  
  
• Sender cannot send more than wnd unacknowledged bytes to the receiver
