As the developing of Beidou navigation positioning technology and the wireless Internet, the demand of the mobile phone location service is increasingly urgent. And the location information sharing between each other becomes an important research focus, and also the core of the current location based service (LBS) software. At present, all the related LBS software is based on C/S architecture, developed...
DNS is one of the important names in web-based information technology that allows users to be able to browse the desired information. DNS service has some similarities with a list of phone book that stores telephone numbers and addresses. To perform the function, the DNS service configured on a special machine that serves the request is a DNS Server. The reliability and accuracy of a DNS server in...
Content-Centric Networking (CCN) is a promising framework for the next generation Internet architecture, by exploiting ubiquitous in-network caching to minimize content delivery latency and reducing the network traffic. In this paper, we introduce a neighborhood aware mechanism for content caching, named Neighborhood Aware Caching and Interest Dissemination (NACID) that accounts for the popularity...
The Domain Name System (DNS) is a key part of the infrastructure of the Internet. Recent discussions have centered on the removal of the shared DNS resolver and the use of a local full-service resolver instead. From the viewpoint of the cache mechanism, these discussions involve removing the shared DNS cache from the Internet. Although the removal of unnecessary parts from a total system tends to...
To address the challenges raised by the Internet usage evolution over the last years, the Content-Centric Networking (CCN) has been proposed. One key feature provided by CCN to improve the efficiency of content delivery is the in-network caching, which has major impact on the system performance. In order to improve caching effectiveness in such systems, studying the functioning of CCN in-network storage...
This paper presents an architecture to provide endto- end per-user services with support to client mobility, designed according to the SDN and NFV paradigms. Our service platform dynamically configures and launches service requests when the client connects to the network, which are used by a multidomain orchestration system to arrange the required network configuration and computational resources...
Internet enabled medical devices offer patients with a level of convenience. In recent years, the healthcare industry has seen a surge in the number of cyber-attacks. Given the potentially fatal impact of a compromised medical device, this study aims to identify vulnerabilities of medical devices. Our approach uses Shodan to obtain a large collection of IP addresses that will be passed through Nessus...
The Internet of Things (IoT) ecosystem, is constantly growing and attracting interest for next generation information and communication infrastructures. In this paper we focus on the exploitation of IoT platforms for remote healthcare status monitoring within the context of the so called connected health applications. In this context users and most importantly healthcare service providers and first...
With the growing popularity of smart things and the omnipresence of wireless communications, the Internet continues to revolutionize from the Internet of hosts, the Internet of People, to the Internet of Things (IoT). Intelligent and scalable orchestration of massive IoT objects using a multitier architecture are critical to embrace the vision of IoT. This paper presents our vision and our initial...
This paper presents an economic e-Learning prototype for boosting up agricultural knowledge in rural regions of Thailand. The proposed prototype is designed on low-resource and mobility concepts. An e-Learning service is utilized for local self-learning and local staff to instruct contents. Due to the limitations and problems of ICT infrastructure, we design our system to function in two modes which...
Inter-domain link congestion can be caused by either under-provision or peer disputes. TSLP and M-Lab are two representative network-tomographic methods to detect congestion on inter-domain links. In this work, we propose a performancecost framework to evaluate and compare the two methods via a simulator built atop NS-3. Via detailed simulations, we obtained some insights on the two approaches and...
Accurate information about address and block usage in the Internet has many applications in planning address allocation, topology studies, and simulations. Prior studies used active probing, sometimes augmented with passive observation, to study macroscopic phenomena, such as the overall usage of the IPv4 address space. This paper instead studies the completeness of passive sources: how well they...
Serving user requests from near-by caches or servers has been a powerful technique for localizing Internet traffic with the intent of providing lower delay and higher throughput to end users while also lowering the cost for network operators. This basic concept has led to the deployment of different types of infrastructures of varying degrees of complexity that large CDNs, ISPs, and content providers...
Anycast-based services today are widely used commercially, with several major providers serving thousands of important websites. However, to our knowledge, there has been only limited study of how often anycast fails because routing changes interrupt connections between users and their current anycast site. While the commercial success of anycast CDNs means anycast usually works well, do some users...
HTTP constitutes a dominant part of the Internet traffic. Today's web traffic mostly consists of HTTP/1 and the much younger HTTP/2. As the traffic of both protocols is increasingly exchanged over encryption, discerning which flows in the network belong to each protocol is getting harder. Identifying flows per protocol is however very important, e.g., for building traffic models for simulations and...
Various methods have been proposed for creating and maintaining lists of potentially filtered URLs to allow for measurement of ongoing internet censorship around the world. Whilst testing a known resource for evidence of filtering can be relatively simple, given appropriate vantage points, discovering previously unknown filtered web resources remains an open challenge. We present a novel framework...
Coded caching is a technique that generalizes conventional caching and promises significant reductions in traffic over caching networks. However, the basic coded caching scheme requires that each file hosted in the server be partitioned into a large number (called the subpacketization level) of non-overlapping subfiles. From a practical perspective, this is problematic as it means that prior schemes...
User Generated Content (UGC) is projected to make up a significant part of the total Internet traffic in the future. As such, it will significantly contribute to the total cost for Internet traffic worldwide. Arguably, UGC is a suitable content type for which the Internet Service Providers (ISPs) can take initiative and enter the content delivery market. However, despite its significance, UGC content...
Linking the growing IPv6 deployment to existing IPv4 addresses is an interesting field of research, be it for network forensics, structural analysis, or reconnaissance. In this work, we focus on classifying pairs of server IPv6 and IPv4 addresses as siblings, i.e., running on the same machine. Our methodology leverages active measurements of TCP timestamps and other network characteristics, which...
The report addresses a remote molecular diagnostics system for studies of the edge plasma inT-10 tokamak at National Research Centre Kurchatov Institute. Web control of a monochromator and a CCD camera based on Internet technologies was used to monitor radiation. The structure and communications chart of the software components implemented in the system are described. A special web application has...
