Overview:

Recent studies have demonstrated the utility of alternate paths in improving connectivity of two end hosts. However studies that comprehensively evaluate the tradeoff between its effectiveness and overhead are lacking. This paper carefully characterizes and evaluates the trade-off between the efficacies of alternate path routing in improving end-to-end delay and loss, and the overheads introduced by alternate routing methodology. This would help to test the scalability of an overlay network. The authors collected ping data on PlanetLab and studied the above trade-off under different parameter settings such as path sampling frequency, overlay-connectivity, number of overlay hops etc.
