Managing Traffic with ALTQ

ALTQ is a package for traffic management. ALTQ includes a queueing framework and several advanced queueing disciplines such as CBQ, RED, WFQ and RIO. ALTQ also supports RSVP and diffserv. ALTQ can be configured in a variety of ways for both research and operation. However, it requires understanding of the technologies to set up things correctly. In this paper, I summarize the design trade-offs, the available technologies and their limitations, and how they can be applied to typical network settings.
