class selector

The tactics of the class selector are the key to winning the carnival.

Class Selector PHBs-which maintain backward compatibility with the IP Precedence field.

In order to maintain backward compatibility with network devices that still use the Precedence field, DiffServ defines the Class Selector PHB.

The negation pseudo-class accepts any simple selector: A type selector, universal selector, attribute selector, class selector, ID selector, or pseudo-class.

In the DS field, a range of eight values (Class Selectors) is used for backward compatibility with the IP precedence specification in the former TOS field.

If a packet is received from a non-DiffServ aware router that used IP precedence markings, the DiffServ router can still understand the encoding as a Class Selector code point.
