“…Xiaosong and Kai [Xiaosong and Kai, 2009] and Brinkmeier et al [Brinkmeier et al, 2009] studies highlight that the security state for P2P systems is worse unlike ClientServer system in which illegal or unauthorized data access can be prevented by a central authority (server) which provides level of access to the clients (users), monitors and maintain logs of all the data requests and transfers made by these authorized users. In contrast to Client-Server system, P2P systems are not considered secure because of the absence of a centralized authority that can vouch for security parameters.…”

“…Resilience is of significant importance for P2P streaming, since perceived media quality suffers noticeably upon failures [9]. In addition, P2P streaming applications are built on top of communication infrastructures and, therefore, failures in the underlay network also have an adverse impact on the performance of the streaming system.…”

“…Due to these network dynamics, re-routings might be necessary, leading to an increase in packet delay. Also the overlay network can become partitioned if a great number of links break down [9]. Furthermore, if neighbors are not selected properly, this can also have adverse effects on resilience.…”

Enabling resilient P2P video streaming: survey and analysis

et al. 2011

Peer-to-Peer (P2P) techniques for multimedia streaming have been shown to be a good enhancement to the traditional client/server methods when trying to reduce costs and increase robustness. Due to the fact that P2P systems are highly dynamic, the main challenge that has to be addressed remains supporting the general resilience of the system. Various challenges arise when building a resilient P2P streaming system, such as network failures and system dynamics. In this paper, we first classify the different challenges that face P2P streaming and then present and analyze the possible countermeasures. We classify resilience mechanisms as either core mechanisms, which are part of the system, or as cross-layer mechanisms that use information from different communication layers, which might inflict additional costs. We analyze and present resilience mechanisms from an engineering point of view, such that a system engineer can use our analysis as a guide to build a resilient P2P streaming system with different mechanisms and for various application scenarios.

“…It has also been used to find the most critical element in industrial symbiotic networks (Chopra & Khanna 2014), to identify which communities are more vulnerable in network systems and be able to prioritize resources to protect the critical elements (Rocco S. & Ramirez-Marquez 2011) and to study critical infrastructure connection and topology (Eusgeld et al 2009;Ouyang 2014). Likewise, it has been applied in analyzing vulnerabilities in process plants in particular cascading effects (Khakzad & Reniers 2015), to improve resilience in communication networks infrastructure (Brinkmeier et al 2009), and to improve resilience in air traffic management (Cook et al 2015;Dunn & Wilkinson 2015).…”

A framework to study the resilience of organizations: a case study of a nuclear emergency plan

Nowadays, building resilience is a key topic in many research fields such as Management, Engineering, Psychology or Ecology. The frequency increase of natural and anthropogenic disasters and the consciousness about their effects are among the reasons why resilience has gained importance and Governments are investing money in boosting the resilience of organizations, infrastructure, cities, individuals, etc. However, there is not much research on specific methodologies to design resilient organizations. A main goal of our research is to improve this aspect providing a framework to design resilient organizations. We explain how to design resilient organizations based on the Viable System Model principles. Then, we focus on an important aspect for being resilient: the communications. We use as a case study a Nuclear Emergency Plan from Spain to show the applicability of our framework. Since the communications in an organization can be modeled as a diffusion process in multiplex networks, and we did not find any suitable architecture to study them in the context of our case study, the architecture we design in this thesis is generic and allows us to model and simulate any kind of diffusion process in a dynamic multiplex network. iii Resumen El desarrollo de la resiliencia es un campo de investigación importante en ámbitos como el Management, la Ingeniería, la Psicología o la Ecología. La importancia del estudio de la resiliencia se ha visto desarrollada por el aumento tanto de desastres naturales como antropogénicos, así como por el desarrollo de conciencia acerca de sus efectos. Estas razones de peso han influido en que los Gobiernos estén invirtiendo recursos en la mejora de la resiliencia de organizaciones, infraestructuras, ciudades, individuos, etc. Sin embargo, a pesar de su importancia, el número de trabajos de investigación que se centran en el desarrollo de metodologías específicas para el diseño de organizaciones resilientes es reducido. El principal objetivo de esta investigación es mejorar este aspecto introduciendo un marco para el diseño de organizaciones resilientes. Para alcanzar este objetivo, se explica cómo emplear el Modelo de Sistemas Viables para el diseño de estas organizaciones. Nos hemos centrado en uno de los aspectos clave de la resiliencia: las comunicaciones. Para ello, se ha usado el caso de estudio del plan de emergencia de una central nuclear en España. Las comunicaciones en una organización pueden modelarse como un proceso de difusión en redes multiplex. Buscamos arquitecturas aplicables a nuestro caso de estudio. Sin embargo, no se ha encontrado ninguna que cumpliera con los requisitos que se necesitaban. Este hecho, nos ha llevado a proponer una nueva arquitectura, que además de permitir estudiar la difusión de información en una organización, permite estudiar otros procesos de difusión en redes multiplex. v I want to express my gratitude to: My thesis supervisors Dr. Adolfo López Paredes and Dr. Gabriel Wainer for being a guide during these years. Thanks for sharing your knowledge,...
