WebQoS Data Fields. Quality of service decisions are based on the contents of the following packet fields: CoS (three bits): Class of service (CoS) is a 3-bit field in Ethernet frame headers using VLAN tagging. The field specifies a priority value between zero and seven. Class of service operates at Layer 2.
