Apparatus and method for enabling intserv quality of service using diffserv building blocks

摘要

A method and apparatus for enabling INTSERV guaranteed/controlled-load service using DIFFSERV building blocks are described. In one embodiment, the method includes the identification of packets from an incoming traffic stream that belong to one of a plurality of flows receiving a contracted quality of service (QoS). Once identified, it is determined whether each respective, identified packet conforms to a predetermined traffic specification for a respective flow to which the respective identified packet belongs. Next, each conforming packet is assigned to a queue from one or more available queues. Finally, packets are selected from each of the one or more queues for transmission in order to maintain performance of each selected packet to the predetermined traffic specification for the respective flow to which the respective packet belongs.
