Towards More Realistic Network Simulations: Leveraging the System-Call Barrier

Abstract. Network simulations play a substantial role in evaluating network protocols. Simulations facilitate large-scale network topologies and experiment reproducibility by bridging the gap between analytical evaluation and real-world measurements. A recent trend in discrete event network simulations is to enhance simulation realism and reduce duplicate implementation efforts by maximizing code reuse. Despite such efforts, it is not yet possible to run arbitrary network applications in stateof-the-art network simulators. As a consequence, researchers are required to maintain separate protocol implementations: one for real-world measurements and one for simulations. We review existing approaches that maximize code reuse in simulations, compare their limitations, and propose a novel architecture for protocol simulation that overcomes those restrictions.

“…It has much more Layer 3 and 4 facilities than the default ns-3 protocol stack, and allows program running on it to have direct access to the MAC Layer, which is required by CarGeo6. To explain in a technical way, DCE runs several Library Linux Operating Systems [12,13] in a single process, and connect its networking and timing backend to ns-3 facilities. The user programs can be executed in the simulated library OS efficiently.…”

International audienceVehicular Ad-hoc Network (VANET) is a type of Mobile Ad-hoc Network (MANET) which is specialized for vehicle communication. GeoNetworking is a new standardized network layer protocol for VANET which employs geolocation based routing. However, conducting large scale experiments in GeoNetworking softwares is extremely difficult, since it requires many extra factors such as vehicles, stuff, place, terrain, etc. In this paper, we propose a method to reproduce realistic results in simulation with the same software implementation. The key idea of the method is to calibrate simulator with the results of real world testbed experiments. After the simulator was calibrated, some extended experiments were carried out. Through these experiments, the fundamental functions of the GeoNetworking implementation (BTP, Greedy Forwarding, etc.) are verified, while an issue in algorithm was discovered and analyzed

“…Today, two complementary approaches are widely used to evaluate the performance of networking protocols: simulators and emulators. Recently, Direct Code Execution (DCE) [1,6,11] has been proposed. This framework benefits from the pros of both simulation and emulation, while limiting the main Permission to make digital or hard copies of all or part of this work for personal or classroom use is granted without fee provided that copies are not made or distributed for profit or commercial advantage and that copies bear this notice and the full citation on the first page.…”

We propose to demonstrate Direct Code Execution (DCE), a framework that enables to execute nearly unmodified applications and Linux Kernel code jointly with the ns-3 simulator. DCE allows therefore fully deterministic reproducibility of network experiments. DCE also supports larger scale scenarios than real-time emulators by using simulation time dilatation. In this demonstration, we will showcase two main scenarios: (1) a basic example describing how to integrate in DCE the Data Center TCP (DCTCP) Linux kernel patch, and then how to customize this protocol and run it on different scenarios; (2) a more advanced use case demonstrating how to benefit from DCE to build a rich and realistic evaluation environment for Software Defined Wireless Networks based on Open vSwitch and the NOX SDN controller.
