The NEC SL1100 supports two methods formarking the ToS byte: IP precedence DSCP (Diffserv)IP PrecedenceIP Precedence uses the first 3 bits of the ToS field to give eight possibleprecedence values (0~7). Under normal circumstances the higher the numberthe higher the priority. However this is left to the network administrator forsetup. The administrator may assign this in exactly the opposite manner withthe lower values having a higher priority. Below are the eight common valuesfor IP precedence. 000 is an IP precedence value of 0, sometimes referred to as routine orbest effort. 001 is an IP precedence value of 1, sometimes referred to as priority. 010 is an IP precedence value of 2, sometimes referred to as immediate. 011 is an IP precedence value of 3, sometimes referred to as flash. 100 is an IP precedence value of 4, sometimes referred to as flashoverride. 101 is an IP precedence value of 5, sometimes called critical. 110 is an IP precedence value of 6, sometimes called internetworkcontrol. 111 is an IP precedence value of 7, sometimes called network control.
