Question 1

Briefly describe each of the eight levels of precedence.

Accepted Answer

There are eight levels of precedence. Level 0 is set for routine traffic that has no priority. Levels 1 through 5 are for prioritized traffic with a higher value, indicating a higher priority. Precedence Levels 6 and 7 are reserved for network and internetwork control packets.
One example of precedence use is Voice over IP (VoIP). The precedence for VoIP traffic may be set to Level 5 to support VoIP real-time delivery needs and to ensure minimum delay and best possible voice/sound quality.
