QUALITY OF SERVICE
QoS (Quality of Service) is a traffic class rule to classify the upstream traffic, assign queuing priority and optionally
overwrite the IP header TOS byte. This is to ensure that the delay-sensitive traffic has higher priority to go to Internet.
IP Precedence and IP TOS (Type of Service) marking, once enabled, will overwrite the correspondent TOS byte in the
IP haeder. These features, along with Differentiated Service Configuration, are valid only when your ISP has implement
these services.
