Abstract

We sketch a gradually deployable QoS architecture which is exclusively based on congestion control; our idea is not to prioritize traffic at all within the network, but to rely upon a framework that is fully distributed and comprised of building blocks that provide the right degree of isolation.

Zusammenfassung

Wir skizzieren eine QoS-Architektur, die ausschließlich auf Staukontrolle basiert; unsere Idee ist, Verkehr überhaupt nicht innerhalb des Netzwerks zu priorisieren, sondern sich auf ein Framework zu stützen, das völlig verteilt ist und aus Bausteinen besteht, die den richtigen Grad der Isolierung bieten.
