With the rapid development of the Internet, especially in recent years, the development of mobile Internet is increasingly rapid. Message push, which is an important way for mobile client to publish information and make communication, plays a significant role in mobile Internet. MQTT protocol is one of the implementation technologies of message push in Android system with low power consumption and...
Nowadays, many school teachers start to execute E-testing in classrooms due to its time and labor-saving. It is not easy that teachers want to block access to the Internet for online cheating activities. Therefore, an offline E-testing system is needed. However, existing offline E-testing systems are always developed ad hoc for particular purpose and procedures. This paper presents a general-purpose...
The analysis of the threats of identity theft and infection of websites indicates that antivirals are ineffective for websites, because hosting does not conduct continuous monitoring for viruses on their servers due to large amounts of user data, and RAID cannot save data, because they only duplicate them, and in the case of infection with a virus they merely memorize a changed file. We have developed...
Online experiments are frequently used at internet companies to evaluate the impact of new designs, features, or code changes on user behavior. Though the experiment design is straightforward in theory, in practice, there are many problems that can complicate the interpretation of results and render any conclusions about changes in user behavior invalid. Many of these problems are difficult to detect...
As one of the basic data resources of Internet, IPv4 address is the most important identity for terminal users to access online resources. With the development of modern Internet, more and more intelligent applications need the terminal's geolocation information to supply high quality services. How to locate the geolocation of the source IP address has become a very important topic in Internet research...
CDNs are today the most scalable way of distributing content. Thanks to CDN interconnection even smaller operators can achieve global footprint. The main cost of this operation is the added latency because requests have to traverse multiple autonomous networks. The work in this article was able to quantify the real impact of this phenomenon and to point to its drawbacks and potential solutions.
Gathering and analyzing statistic information is essential for every college or university, which cares about their students. This paper aims at giving theoretical overview of modern web page development and statistics gathering methods, analyzing present state of TUKE and designs a new statistics system, where emphasis is placed primarily on comfortable work of students with the system.
Stored SQL injection (SQLI) and Stored Cross Site Scripting (XSS) are the top most critical web application vulnerabilities in present time. Previous researches have shown that black-box scanners have relatively poor performance in detecting these two vulnerabilities. In this paper, we analyze the performance and detection capabilities of latest black-box web application security scanners against...
As most of the malware nowadays use Internet as their main doorway to infect a new system, it has become imperative for security vendors to provide cloud-based solutions that can filter and block malicious URLs. This paper presents different practical considerations related to this problem. The key points that we focus on are the usage of different machine learning techniques and unsupervised learning...
The sensor node signal interface is the channel for sensor connecting to sensor node. Therefore, in order to verify the conformance between sensor network signal interface and signal interface standard, the design and implementation of WSN signal interface conformance test system based on web wsa presented. The test content included the signal interface description file, signal type supported by interface,...
In this article we present our first approach in using Passive Testing (used in protocol and software conformance checking) and Process Mining (used in enterprise workflow analysis) techniques for analyzing DNS operation traces.
Network monitoring system is an important task for network administrator to monitor states of the operation of network devices, servers, network services, or network traffics. This task is often solved by setting-up a monitoring server and implement agents at monitored objects. This paper presents a solution to monitor Hot-IPs in high speed network at ISP side. It does not need to specify which objects...
The Internet Engineering Task Force (IETF) standardized and published the IPv4 protocol in September 1981. After almost 30 years, the remaining IPv4 addresses have been distributed by Internet Assigned Numbers Authority (IANA) in February 2011. Due to the exhaustion of IPv4 addresses, the transition from IPv4 to IPv6 is required definitely. The IPv6 protocol and address will gradually replace IPv4,...
Quality of Experience (QoE) is a measure of a customer's experiences with a service (web browsing, TV broadcast, call to a Call Center). QoE focuses on the entire service experience, and is a more holistic evaluation than the more narrowly focused UX (user experience, focused on a software interface) and CX (customer experience, support focused). Measuring the bottleneck link bandwidth along a path...
The paper presents results from the SEE TV-WEB project, which is tackling the problem of the digital divide by extending the HbbTV standard solution for provisioning of advanced services. Excellent coverage of DTT networks compared to the broadband Internet access and a large number of users being accustomed to the TV as the main device enable tackling of the digital divide. Many benefits of such...
We propose two robust methods for anomaly detection in dynamic networks in which the properties of normal traffic evolve dynamically. We formulate the robust anomaly detection problem as a binary composite hypothesis testing problem and propose two methods: a model-free and a model-based one, leveraging techniques from the theory of large deviations. Both methods require a family of Probability Laws...
Interoperability testing is an important part of the lifecycle of a protocol. Interoperability tests not only help to reduce implementation bugs, but they also often improve the accuracy of a protocol specification. In a pursuit to improve Network Configuration (NETCONF) interoperability and foster it for community-based education, we have developed and deployed a NETCONF Interoperability Lab. The...
The SIP(Session Initiation Protocol) is the core control protocol of the Next Generation Networks(NGN), which is used for initiating, modifying and tearing down multimedia sessions on IP data network. Because the SIP server is the core facility of NGN, its realization is especially important. One way to realize the SIP server is the proxy server, which mainly provides routing service. Namely, it ensures...
The paper describes the developed multiaccess internet application for collective realization of listening tests which are very important for evaluation of the synthetic speech quality used in text-to-speech systems or human-machine interfaces. This application together with testing speech and image corpora are stored on the server PC, where the listening tests are also executed. The application communicates...
Nowadays public transportation is needed given the current increasing transportation needs in the community because of the density of private vehicles that causes congestion everywhere. Given these reasons, currently people prefer to use public transportation to get to a location or perform daily life activities. But the problem is lack of information of public facilities and routes of available public...
