Overview:

This paper describes a proportional differentiated services architecture based on MPLS constraint based routing for traffic engineering. Three classes are defined: Gold, Silver and Bronze. The Gold class gets the best service and, whenever possible, the double of the bandwidth of the Silver class. The Bronze class is a best effort class that gets the unused bandwidth from the other classes. The simulation results show that the proposed mechanisms avoid priority inversions for all load patterns. Additionally, the traffic engineering MPLS mechanisms improve the total goodput, by using alternative paths.
