Résumé: Aggregating the traffic to different forwarding equivalence class (FEC) is an indispensable and significant phase for layer-3 and layer-2 hybrid switching. Regarding existed schemes mainly focusing on high efficiency of network resource but taking little consideration on user's demand, we put forward a new scalable framework for traffic partitioning based on some generalized concepts and optional priority serving mechanism to satisfy both users and networks' requirement. In this letter, the design of the conceptual framework regarding the key technologies and corresponding adaptive algorithms are presented. Simulation using real Internet traces shows that our adaptive adjustment can guarantee delivering bound, the maximum delay of concerned packets while consuming bandwidth around the average traffic rate.
