ModelNet-TE: An Emulation Tool for the Study of P2P and Traffic Engineering Interaction Dynamics

Free registration required

Executive Summary

In the Internet, P2P application performance may be determined by the interaction of two independent dynamics: on the one hand, by the end-to-end control policies applied at the P2P application layer (L7); on the other hand, by Traffic Engineering (TE) decisions taken at the network level (L3). To study L7/L3 interaction in realistic settings, the authors present a framework for the emulation of TE capabilities. More specifically, they augment the ModelNet network emulator with multi-path capability: their ModelNet-TE implementation is general enough to deploy other TE algorithms in the ModelNet-TE core.
