     Flow control is the mechanism that determines when to send a Data
     or expedited messages. Flow control is performed separately for
     normal and expedited data. During transport connection formation,
     each end of the connection determines the kind of flow control
     policy it expects when acting as a data receiver. It is not
     required that both end operate with the same flow control policy.
