A team from INRIA, France and the University of Tokyo presented a Direct Code Execution (DCE) demonstration at the 17th ACM International Conference on Modeling, Analysis and Simulation of Wireless and Mobile Systems (MSWiM) in Montreal on September 22. Entitled “Realistic Evaluation of Kernel protocols and Software Defined Wireless Networks with DCE/ns-3,” the demonstration showcased 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; and (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. DCE is a framework enabling the execution of real application and Linux kernel code within an ns-3 simulation context, allowing for a high degree of implementation realism and debugging capabilities. Full support for SDN is planned for the next DCE release.
