On the existence of experimentally-driven research methodology

Anastasius Gavras
2010 Zenodo  
This white paper attempts to scope the area of experimentally driven research by proposing a methodology and related terminology that should help research in the ICT domain to understand how this methodology  ...  This white paper is intended as the first step in a controversial debate that should take place in the community of FIRE projects (Future Internet Research and Experimentation) and other interested stakeholders  ...  Large-scale trials and pilots The infrastructure for conducting large-scale experiments and testing is currently constructed via federation of testbeds.  ...

Large-Scale Deployment in P2P Experiments Using the JXTA Distributed Framework [chapter]

Gabriel Antoniu, Luc Bougé, Mathieu Jan, Sébastien Monnet
2004 Lecture Notes in Computer Science  
The interesting properties of P2P systems (high availability despite peer volatility, support for heterogeneous architectures, high scalability, etc.) make them attractive for distributed computing.  ...  However, conducting large-scale experiments with these systems arises as a major challenge. Simulation allows only to partially model the behavior of P2P prototypes.  ...  We also thank Bernard Traversat, Senior Architect of Project JXTA at Sun Microsystems, for his useful comments, as well as the reviewers, for their suggestions.  ...

Practical Evaluation of Large Scale Applications [chapter]

Tiago Jorge, Francisco Maia, Miguel Matos, José Pereira, Rui Oliveira
2015 Lecture Notes in Computer Science  
This stems not only from the inherent complexity of writing and reasoning about distributed software, but also from the lack of tools for testing and evaluating it under realistic conditions.  ...  Designing and implementing distributed systems is a hard endeavor, both at an abstract level when designing the system, and at a concrete level when implementing, debugging and evaluating it.  ...  Test beds such as PlanetLab [3] or a cloud infrastructure allow to perform very large scale deployments, but system observability and reproducibility of testing conditions on normal and faulty conditions  ...

Minha: Large-Scale Distributed Systems Testing Made Practical

Nuno Machado, Francisco Maia, Francisco Neves, Fábio Coelho, José Pereira, Michael Wagner
2020 International Conference on Principles of Distributed Systems  
Testing large-scale distributed system software is still far from practical as the sheer scale needed and the inherent non-determinism make it very expensive to deploy and use realistically large environments  ...  Our experiments with two distributed systems show the usefulness of Minha in disclosing errors, evaluating global properties, and in scaling tests orders of magnitude with the same hardware resources.  ...  We believe that Minha opens a number of interesting research opportunities in the field of distributed systems testing and debugging.  ...

Experimental evaluation of distributed middleware with a virtualized Java environment

Nuno A. Carvalho, João Bordalo, Filipe Campos, José Pereira
2011 Proceedings of the 6th Workshop on Middleware for Service Oriented Computing - MW4SOC '11  
The correctness and performance of large scale service oriented systems depend on distributed middleware components performing various communication and coordination functions.  ...  We address this challenge with MINHA, a system that virtualizes multiple JVM instances within a single JVM while simulating key environment components, thus reproducing the concurrency, distribution, and  ...  For instance, ModelNet [15] simulates a WAN in a LAN to evaluate large scale distributed programs.  ...

Controlling IP Falsifying Using Realistic Simulation

Govindavaram Madhusri, Chakunta Venkata Guru Rao
2013 International journal of network security and its applications  
However, this technique does not allow large number of networks, which is a common misapprehension for those unfamiliar with the practice.  ...  The study of Internet-scale events such as worm proliferation, distributed denial-of-service attacks (DDoS), flash crowds, routing volatilities, and DNS attacks depend on the formation of all the networks  ...  Even distributed versions of network simulators such as GTNetS and PDNS, designed for large-scale events, have limited scalability because each packet and its handling are simulated in minute detail.  ...
