We present the architecture and partial proof of concept implementation of distributed responder ARP (DR-ARP), a software defined networking (SDN) enabled enhancement of the standard address resolution protocol (ARP). It is intended to improve network security and performance by exerting much greater control over how ARP traffic flows through the network as well as over what actually delivers the ARP service. Using SDN to centralize this service improves the security and performance of ARP in a way transparent to the end hosts.

Many believe that Cloud will reshape the entire ICT industry as a revolution. In this paper, we aim to pinpoint the challenges and issues of Cloud computing. We first discuss two related computing paradigms - Service-Oriented computing and Grid computing, and their relationships with Cloud computing We then identify several challenges from the Cloud computing adoption perspective. Last, we will highlight the Cloud interoperability issue that deserves substantial further research and development.

The tradeoff between scalability and consistency has been addressed by deploying distributed applications in the cloud. However, cloud-based applications penalize performance with the unavoidable latency and jitter resulting from the geographical distance between clients and application servers. Fog computing architectures mitigate this impact by deploying state fragments and computing power on surrogate servers at the network edge. To improve performance, one must deploy each fragment of the application state at the most convenient surrogate and maintain an efficient coordination when manipulating state stored in multiple locations. This paper formalizes a two-tier view synchronous group communication model for Fog computing to improve performance of large scale mobile distributed applications and evaluates it using data derived from a real dataset.

Intelligently discovering knowledge and principles hidden in massive amounts of distributed and dynamic sources is a challenging issue, since the connectivity of sources and mobility of contents are frequent changing. For achieving intelligently discovering knowledge and principles in network environments, it requires a strong adaptive mechanism of distributed reasoning to discover the indirect and dynamic semantics in content-centric networking. In this paper, we propose a novel ad-hoc scheme for distributed reasoning by extending the name-based routing mechanism in content centric networking. The ad-hoc scheme of distributed reasoning is a native process of the content-centric networking. First, a two-stage reasoning mechanism is presented for reasoning query forwarding and knowledge reasoning. And then for guiding original or evolved queries to all right sources and supporting the knowledge integration in the way back, a recursive reasoning procedure and various reasoning rules are introduced.

Practical applications of quantum computers require millions of physical qubits and it will be challenging for individual quantum processors to reach such qubit numbers. It is therefore timely to investigate the resource requirements of quantum algorithms in a distributed setting, where multiple quantum processors are interconnected by a coherent network. We introduce an extension of the Message Passing Interface (MPI) to enable high-performance implementations of distributed quantum algorithms. In turn, these implementations can be used for testing, debugging, and resource estimation. In addition to a prototype implementation of quantum MPI, we present a performance model for distributed quantum computing, SENDQ. The model is inspired by the classical LogP model, making it useful to inform algorithmic decisions when programming distributed quantum computers. Specifically, we consider several optimizations of two quantum algorithms for problems in physics and chemistry, and we detail their effects on performance in the SENDQ model.

We examine longitudinal and lateral safety-critical scenarios as they arise in VANETs, in the presence of concurrency and unreliable inter-vehicular communications. The Fast distributed Agreement (FastDA) problem, as well as solutions to the longitudinal and the lateral instantiations of FastDA, are examined and informally specified. Analytical expressions of worst-case time bounds for reaching agreement are provided. We verify that stringent safety requirements are met through realistic examples drawn from various safety-critical scenarios.

Applications of Information-Centric networking (ICN) technology to future internet of things (IoT) and distributed edge/fog computing are widely discussed in various research committees. In this paper, we demonstrate a real-time video streaming scenario using CeforeSim, an NS-3 based ICN simulator. CeforeSim is based on Cefore, an open-source implementation of ICN, which is compliant with the CCNx packet format standardized by the IRTF ICN Research Group (ICNRG). The virtual interfaces provisioned in CeforeSim expedite seamless interaction between the simulated nodes and physical nodes that run the Cefore applications, thereby affording performance evaluations in various scenarios, such as handover of mobile nodes, large-scale sensor networks, and distributed edge/fog computing with the real environments.

Three practical meteorological applications with different characteristics are used to highlight the usability of a computer science workflow middleware called ASKALON by allowing easy access to distributedcomputing for atmospheric scientists. Utilizing Cloud and Grid computing, this paper shows use case scenarios fitting a wide range of applications from operational to research studies with real world examples from meteorological research. The paper concludes that distributedcomputing is easily usable for meteorological problems using ASKALON. This powerful tool allows simple and cost effective access to computing capacity from Grid and Cloud environments.

Content-Centric networking (CCN) is an alternative to host-centric networking exemplified by today's Internet. CCN emphasizes content distribution by making content directly addressable. Named-Data networking (NDN) is an example of CCN being considered as a candidate next-generation Internet architecture. One key NDN feature is router-side content caching that optimizes bandwidth consumption, reduces congestion and provides fast fetching for popular content. Unfortunately, the same feature is also detrimental to privacy of both consumers and producers of content. As we show in this paper, simple and difficult-to-detect timing attacks can exploit NDN routers as "oracles" and allow the adversary to learn whether a nearby consumer recently requested certain content. Similarly, probing attacks that target adjacent content producers can be used to discover whether certain content has been recently fetched. After analyzing the scope and feasibility of such attacks, we propose and evaluate some efficient countermeasures that offer quantifiable privacy guarantees while retaining key features of NDN.
