About DSCP
DSCP consists of 6 bits of IP packet header. It uses ToS field. This byte is also called
DSCP byte. Its position among the byte is as follows:
DS5 DS4 DS3 DS2 DS1 DS0 CU CU
DSCP priority: 6 bits (DS5-DS0)
Unused (CU): 2 bits
The values of DSCP priority are 64 (0~63). 0 is the lowest priority level, and the 63 is
the highest priority level. In fact, DSCP field is the superset of the IP priority field.
DSCP field is backward compatible with the IP priority. At present, the defined default
DSCP is 0. Class selector DSCP is backward compatible with the IP priority. The
values are 8, 16, 24, 32, 40, 48, and 56. Usually, EF (Expedited Forwarding) is used
for low delay service and the recommended value is 46 (101110).
AF (assured
forwarding) defines 4 service levels, and each service level includes three
descending levels. The following table shows the concrete values as follows:
