“…Additionally, testbed orchestration and experiment execution are often tightly coupled. vBET [18] and LaasNetExp [24] are both closed source, preventing to extend those frameworks. VNEXT [25] and NEPTUNE [5] do not provide the automated setup of basic network services, like DNS or DHCP.…”

Abstract. Analyzing network environments for security flaws and assessing new service and infrastructure configurations in general are dangerous and error-prone when done in operational networks. Therefore, cloning such networks into a dedicated test environment is beneficial for comprehensive testing and analysis without impacting the operational network. To automate this reproduction of a network environment in a physical or virtualized testbed, several key features are required: (a) a suitable network model to describe network environments, (b) an automated acquisition process to instantiate this model for the respective network environment, and (c) an automated setup process to deploy the instance to the testbed.With this work, we present INSALATA, an automated and extensible framework to reproduce physical or virtualized network environments in network testbeds. INSALATA employs a modular approach for data acquisition and deployment, resolves interdependencies in the setup process, and supports just-in-time reproduction of network environments. INSALATA is open source and available on Github. To highlight its applicability, we present a real world case study utilizing INSALATA.

“…Laasnetexp consists of a server and 38 dual-core machines that can be configured to run different operating systems, such as various versions of Windows and Linux [46]. Each machine has four network interfaces per machine using multiple transport protocols with varying numbers of senders, receivers and 500 GB disks.…”

Assuring end-to-end QoS in enterprise distributed real-time and embedded (DRE) systems is hard due to the heterogeneity and transient behavior of communication networks, the lack of integrated mechanisms that schedule communication and computing resources holistically, and the scalability limits of IP multicast in wide-area networks (WANs). This paper makes three contributions to research on overcoming these problems in the context of enterprise DRE systems that use the OMG Data Distribution Service (DDS) quality-ofservice (QoS)-enabled publish/subscribe (pub/sub) middleware over WANs. First, it codifies the limitations of conventional DDS implementations deployed over WANs. Second, it describes a middleware component called Proxy DDS that bridges multiple, isolated DDS domains deployed over WANs. Third, it describes the NetQSIP framework that combines multi-layer, standards-based technologies including the OMG-DDS, Session Initiation Protocol (SIP), and IP DiffServ to support end-to-end QoS in a WAN and shield pub/sub applications from tedious and error-prone details of network QoS mechanisms. The results of experiments using Proxy DDS and NetQSIP show how combining DDS with SIP in DiffServ networks significantly improves dynamic resource reservation in WANs and provides effective end-to-end QoS management.

“…To obtain our traffic trace, the capture tools installed in the experimental platform "LaasNetExp" at LAAS-CNRS 2 are used. LaasNetExp [27] is a generic polymorphic platform for network emulation and experiments. From a specific machine, chosen to be the router for our network topology as in figure 2, incoming data and outgoing data are captured via the network analyser "Wireshark" [28].…”

We investigate the design of a second order sliding mode observer for detecting anomalies in TCP networks. More precisely, based on a fluid model of TCP network, we aim at designing an observer, whose state variables reconstruct some external signals which perturb the nominal behavior of TCP. The proposed methodology is validated via NS-2 simulations. Finally, an experimental setup is proposed to show the effectiveness of our approach.
