specifies how the datagram should be handled. The field could be divided into the following six
subfields:
 PRECEDENCE (3 bits)
 D-Type (Delay Priority, 1 bit)
 T-Type (Throughput Priority, 1 bit)
 R-Type (Reliability Priority, 1 bit)
 M-Type (Monetary Cost Priority, 1 bit)
 UNUSED. PRECEDENCE 3-bits can arrange eight types of priorities corresponding to the 0~7
priority in the following priority diagram. TOS Throughput Priority Mapping works while T-TYPE
in the TOS field of the IP header of the packets received by the switch is configured.
