The dramatic success and scaling of the Internet was made possible by the core principle of keeping it simple in the middle and smart at the edge (or the end-to-end principle). However, new applications bring new demands, and for many emerging applications, the Internet paradigm presents limitations. For applications in this new generation of Internet services, structured overlay networks offer a...
This article describes the problems of the modern network scanning, existing software solutions and areas of its applications. The structure of high-performance network scanner is given. There are outlined the main features of the new network scanner, its usage area and improved characteristics.
“Power Packets” are one of useful ideas of power distribution for a highly-efficient and comfortable society with a low environmental impact and energy efficient systems. It has yet to be shown that it is feasible to generate physical electric power packets and control them with computers. This study aims to organize the past achievements from the point of view of our studies. This study offers a...
Named Data Networking (NDN) is a promising future network architecture. In NDN, caching is widely deployed to improve content delivery. A lot of caching strategies have been proposed to improve caching performance, such as complicated cooperative caching and non-cooperative caching. No-cooperative Probability caching is proposed to increase the content variety across caching nodes, although it enjoys...
Network Address Translation has often been described as an aberration in the evolution of the Internet, and one that will be removed with the completion of the transition of IPv6. This is an opinion in support of NATs, arguing that they are an important step in the evolution of the Internet and may well play a lasting role in this environment.
ISPs face difficulties in optimizing interdomain routing due to the single path routing constraint of BGP. A single best path makes it difficult to optimize routing and is unable to satisfy various application requirements of customers. In this paper, we present a new routing architecture for ISP edge network which breaks this constraint and allows the operator to flexibly assign interdomain paths...
Routers in Content-Centric Networking (CCN) may locally cache frequently requested content in order to speed up delivery to end users. Thus, the issue of caching strategies arises, i.e., which content shall be stored and when it should be replaced. In this work, we employ, and study the feasibility of, novel techniques towards intelligent control of CCN routers that autonomously switch between existing...
Named Data Networking (NDN), a revolution of the IP architecture, provides an information-centric paradigm to transmit video traffic which occupies most of the Internet traffic. However, the data caching schemes exploited by the current NDN can easily result in the unfair distribution of cache space, which is not suitable for performance isolation when there are multiple network users and the cache...
In this paper, we propose a decentralized mobility support architecture, with micro-level name resolution, for information centric networking (ICN) to better manage host mobility, and respond quickly to handover events to avoid data loss. Proposed architecture utilizes localized anchors, carrying new data structures, during packet forwarding to aggregate mobile flows and provide a combination of stateful...
With the widespread availability of connected smart devices, Internet of Things (IoT) is becoming the world's largest computing platform. These large-scale, heterogeneous and resource-constrained devices bring many significant new challenges to the design of efficient and reliable IoT systems. Security is one of the most crucial ones that need to be effectively addressed for the wide adoption of IoT...
In this paper, we present ICN-FC, which is an Information-Centric Networking (ICN) based framework for efficient functional chaining (FC). The key enabling techniques for ICN-FC includes naming semantics, Interest & Data processing and an efficient FC forwarding strategy. By using the proposed solutions, a functional chaining request, which consists of the name of raw data and an ordered set of...
A data-centric network architecture, Named Data Networking (NDN) has been developed to meet applications' growing demands of network effciency and resilience. Currently, the deployment of NDN in real network environments requires careful system design to not only enable NDN but also support IP traffc, considering IP network has been prevalent for decades and almost all the equipments and applications...
Over the past several years, Software Defined Networking (SDN) has emerged as a new and promising paradigm for the management of computer networks. While we have seen many use-cases and deployments of SDN in data center networks, wide-area networks still heavily rely on legacy routing and traffic engineering technologies. Rapidly increasing traffic demands (mainly due to increasing usage of video...
In the current development of renewable energy production, microgrid control is a stringent issue nowadays. This practical approach should benefit of the newest automation and IT&C techniques. The paper addresses, in a particular manner, the main control systems strategies and techniques adapted for the microgrid processes: hierarchical control, model predictive control, multi-agent systems, average-consensus...
The Internet of Things (IoT) enables several heterogeneous devices, sensors, wearables, appliances and many other objects to inter-communicate and provide support for heterogeneous services. An IoT network needs to enable exchange diverse data types including multimedia and sensor data and be capable of handling a large number of IoT objects offering services at high quality levels. This paper proposes...
The emerging technologies in IoT unveils various devices for the convenience of users, but comes with the price of streaming and processing a large amount of data for delivering useful and presentable results. Especially the multimedia content can be estimated as the most expensive to compute and distribute in IoT environments due to the data size and complexity of algorithms. This may cause bottlenecks...
Building the Internet of Things requires deploying a huge number of objects with full or limited connectivity to the Internet. Given that these objects are exposed to attackers and generally not secured-by-design, it is essential to be able to update them, to patch their vulnerabilities and to prevent hackers from enrolling them into botnets. Ideally, the update infrastructure should implement the...
The continuous discovery of exploitable vulnerabilitiesin popular applications (e.g., web browsers and documentviewers), along with their heightening protections againstcontrol flow hijacking, has opened the door to an oftenneglected attack strategy—namely, data-only attacks. In thispaper, we demonstrate the practicality of the threat posedby data-only attacks that harness the power of memorydisclosure...
The WTFast's Gamers Private Network (GPN®) is a client/server solution that makes online games faster. GPN® connects online video-game players with a common game service across a wide-area network. Online games are interactive competitions by individual players who compete in a virtual environment. Response time, latency and its predictability are keys to GPn® success and runs against the vast complexity...
The main design principle of Information-Centric Networking (ICN) is the name based routing, that makes users able to ask for a data object by only using its name, and makes the network deliver data to users from a nearby cache if in-network caching is available. Software-Defined Networking (SDN) decouples the control layer from the data layer, so that the complexity, and network control and management...
