4.10.2.7 Mapping IP TOS Priority
The Type of Service (TOS) octet in the IPv4 header is divided into three parts; Precedence (3 bits), TOS (4 bits), and MBZ (1
bit). The Precedence bits indicate the importance of a packet, whereas the TOS bits indicate how the network should make
tradeoffs between throughput, delay, reliability, and cost (as defined in RFC 1394). The MBZ bit (for "must be zero") is currently
unused and is either set to zero or just ignored.
