QoS architectures define how routers process packets to ensure QoS service guarantees enforced. Existing QoS architectures such as Integrated Services (IntServ), Differentiated Services (DiffServ), and Dynamic Packet State (DPS) share one common property that the packet structure and the function of the routers are closely connected. Packets of one data flow are treated the same all the time at different routers. The authors propose to decouple such connection between packet structures and router functions. In their solution, packets carry as much information as possible, while routers process packets as detailed as possible until their load burden prohibits.
