Remote server vulnerability exploit is one of the most troublesome threat to the Internet security. An effective defense against the remote vulnerability exploit is code randomization, which randomizes the program code address to disrupt the malicious payload execution. Unfortunately, code randomization is particularly susceptible to address exposure vulnerabilities; the leak of a single code or data...
Big volume of bioinformatics data needs high processing powers. BIG-BIO is one of the solutions for addressing these challenges. BIG-BIO is a big data analyst MapReduce Hadoop Cluster for Bioinformatics applications. BIG-BIO is tested by implementing the bioinformatics wordcount problem and its applications using MapReduce programming pattern. BIG-BIO counts the number of occurrence of each word in...
In cloud computing, multiple servers are consolidated into a physical machine in order to reduce the cost of deploying the servers. Guaranteeing the service level objective (SLO) of each server is one of the most important factors in a virtualization system. Particularly, isolating the I/O resources among VMs competing for a shared storage system is challenging. Recently, use of flash based Solid...
As the Internet of Things evolves, many devices that were not previously considered suitable for this trend can now be used as a part of smart interconnected systems. This paper describes the process of adapting a Cisco IR829GW router to be used as both a Cisco IOS platform (for complex networking needs) and an embedded device running Yocto Linux distribution for Internet of Things application deployment...
Linux Server Operating system is widely used in electric power SCADA systems in China. In order to study the performance difference between different distribution Linux Server operating systems so that we can select an appropriate distribution to use, the paper compares four secure Linux server operating system's performance using lmbench benchmarking methodology. The experiments showed that lmbench...
Communication plays a major role in the day to day activities of the world. Communication can be a gesture, phone call or by e-mail. This why most of the governments pay more attention to communication patterns and what people communicate with each other. In modern day information technology plays a major role in private and public sector events. It's better to be having implement security in to the...
File is a super abstraction of hypothetically huge volume of information stored in containers (disk blocks) which is persists for very long time (memory abstraction). File is linear Array of bites and blocks of bytes accessed by multiple clients which is controlled by File system. File System function is disk seek, read maximum information from container and maps file names and offsets to disk blocks...
For the least connections algorithm currently used cannot solve the problem of inaccurately reflecting the load capacity of servers caused by the situation that the difference of resources consumed by different requests is very big, this paper designs a new algorithm named UCM algorithm. It means use the unused rate of the CPU and Memory as the actor to calculate the weight of the server, and introduces...
Cloud computing is now leading-edge Internet technology and virtualization technology is one of the important part of cloud computing system. Virtualization, in computing, refers to the act of creating a virtual (rather than actual) version of something, including but not limited to a virtual computer hardware platform, operating system (OS), storage device, or computer network resources. Docker is...
This paper addresses the performance and service comparison of two different Cloud Computing platforms: Amazon AWS and Microsoft Azure. Platforms are tested in similar virtual environments, namely for micro instances. Performance is measured by the collection benchmark program called Phoronix Test Suite 3, and the results are presented for Apache and Dbench benchmarks.
The Minos+ experiment is an extension of the Minos experiment at a higher energy and more intense neutrino beam, with the data collection having begun in the fall of 2013. The neutrino beam is provided by the Neutrinos from the Main Injector (NuMI) beam-line at Fermi National Accelerator Laboratory (Fermilab). The detector apparatus consists of two main detectors, one underground at Fermilab and the...
Computer security, school security policy and school computers usability should be important for all school computers and network resources users. But instead of implementing security policy, users often unintentionally compromise computer functionality and security out of ignorance or negligence. Since Windows is the default operating system in the majority of Croatian schools, students often have...
Virtualization finds wide application in information and communication technology. Some of these applications can be used in education, to simplify the administration and teaching performance while saving money. In the last few years, computer technology has progressed sufficiently thus facilitate the development of virtual machines that provide a completely new method of using computers and their...
High Performance Distributed Computing has created a new approach to science. High performance can be achieved by distributing the task over different machines, using a better algorithm, using faster computers or by using an MPSoC (Multiple Processor System on Chip). In MPSoC multiple CPUs are connected with each other to accomplish a task as a whole. Each CPU assigned a different task. In this paper...
The transition mechanisms for the first phase of IPv6 deployment are surveyed and the most important DNS64 solutions are selected. The test environment and the testing method are described. As for the selected DNS64 implementations, the performance of both BIND9 and TOTD running under Linux, OpenBSD and FreeBSD are measured and compared. The stability of all the tested DNS64 solutions was analyzed...
Demand Response (DR) is often regarded as the killer application of the emerging smart grid. The ever-growing Internet population and energy consumption makes data centers auspicious candidates with great potential for DR. Besides commercial data centers and large server farms, small data centers scattered in academic or research environments consume considerable amount of energy. Unlike commercial...
The evolution of the information and communication Technologies and the considerable growth of on-line education have increased the use of different media and resources in the structuring of the model of a course. The adequate choice for the structure of courses is fundamental to the motivation and comprehension of the context by the students. The present article relates the experience and validation...
Source code compiling is a non-trivial task that requires many computing resources. As a software project grows, its build time increases and debugging on a single computer becomes more and more time consuming task. An obvious solution would be a dedicated cluster acting as a build farm, where developers can send their requests. But in most cases, this solution has a very low utilization of available...
In this paper, we propose a Network Virtual Platform (NetVP) to develop and verify network accelerator like an IPsec processor. The NetVP provides on-line verification mechanism and is suitable for ESL top-down design flow, supporting developments of un-timed as well as timed models. System development using this NetVP is efficient and flexible since it allows the designer to explore design spaces...
Along with the improvement and development of Linux operation system, using Linux technology to set up the network server has become the development direction of network server. Start from the LVS general architecture, the IPVS software's principle of work analyzed, three kind of IP load equalization technology discussed, According to user ¡®s requirement of construction of high performance, high...
