Flow control may be classified into three types by transmission priority:
Condition 1: Precedence not determined by TOS.
Condition 2: TOS is rewritten; converted TOS determines precedence.
Condition 3: Precedence determined by input IP packet TOS.
Condition 4: Determines the EXP and priority level.
Condition 5: Determines the priority level by EXP.
Flow control is further classified using the following three conditions:
Condition 1: No reserve bandwidth management.
Condition 2: Detected flows that violate bandwidth reservation are discarded.
Condition 3: When a detected flow violates bandwidth reservation, its priority
is lowered.
