Fidelity is the quality of faithfulness or loyalty. Its original meaning regarded duty in a broader sense than the related concept of fealty. Both derive from the Latin word fidÄlis, meaning faithful or loyal.
Network nodes include end-hosts and routers. Fidelity in general is hard to define, but it is possible to compare two methods with respect to their relative fidelity. Fidelity could be based on the amount of detail accounted for in the network (e.g., routing, network congestion, etc.), or in end-hosts (e.g., stack processing, operating system overheads, etc.). Hardware testbeds have improved in scale with recent advancements, with network testbeds scaling to hundreds or more nodes (e.g., EmuLab[1, 2]). However, hardware testbeds cannot by themselves sustain fidelity with increasing scale. In fact, hardware testbeds resort to some form of network simulation underneath to improve fidelity when virtual
