Network traffic is mapped to the desired Class of Service through the classification amd marking of packets. Traffic types are identified by:
- Source and/or destination network/hosts IP Addresses
- Source and/or destination Protocol Ports
- Traffic with premarked IP Precedence or DSCP bits.
After the traffic is classified, the TOS byte must be marked with the appropriate DSCP or IP Precedence values. Using these tools, you can customize your Wide Area Network to provide the best performance based on your application requirements. When you utilized managed service from your carrier, they take care of the classification of date based on a survey that is provided to the customer.
