Class Based Queueing (CBQ) is a packet scheduling discipline that enables hierarchical link-sharing. Compared to other algorithms, it is modular and intuitive in a first approach, and so is implemented and used nowadays. In this paper, we adapt the discipline to schedule critical real-time flows mixed with other kinds of traffic, as is necessary in a DiffServ environment This requires that some guarantees must be provided deterministically, particularly on queueing delay bounds. Yet theoretical… CONTINUE READING
