Abstract

Systems, methods, and apparatus are provided for emulating the performance effect on network traffic flow traversing a node in a communications network. According to one illustrative embodiment, a method of emulating traffic through a node is provided. The method includes generating foreground traffic through the node; simulating a first background traffic having a first weight at the node; simulating a second background traffic having a second weight at the node; determining an effect of the first and second background traffic on the foreground traffic; and making a forwarding decision with respect to the foreground traffic based on the effect.
