New Method of Measuring TCP Performance of IP Network using Bio-computing

The measurement of performance of Internet Protocol IP network can be done by Transmission Control Protocol TCP because it guarantees send data from one end of the connection actually gets to the other end and in the same order it was send, otherwise an error is reported. There are several methods to measure the performance of TCP among these methods genetic algorithms, neural network, data mining etc, all these methods have weakness and can't reach to correct measure of TCP performance. This paper proposed a new method of measuring TCP performance for real time IP network using Biocomputing, especially molecular calculation because it provides wisdom results and it can exploit all facilities of phylogentic analysis. Applying the new method at real time on Biological Kurdish Messenger BIOKM model designed to measure the TCP performance in two types of protocols File Transfer Protocol FTP and Internet Relay Chat Daemon IRCD. This application gives very close result of TCP performance comparing with TCP performance which obtains from Little's law using same model (BIOKM), i.e. the different percentage of utilization (Busy or traffic industry) and the idle time which are obtained from a new method base on Bio-computing comparing with Little's law was (nearly) 0.13%.

Menelaah Lalu Lintas Jaringan Internet Relay Chat (IRC) Yang Berbahaya guna Identifikasi Komunikasi Botnet “Plague”

The research presented in this article aims to identify “plague” botnet communication pattern, with the aid of Wireshark Packet Analyzer as proof of concept (PoC) towards unique communication pattern analysis between infected host and botnet. The research is conducted on public IRC (Internet Relay Chat) network, specifically at the opened domain for botnet research, that is, irc.accesox.net. COMODO Internet Security also used for determining files downloaded by the botnet to identify whether there any malware or not. The observation is done on 60 captured packets, which then the TCP stream excerpt and the protocols hierarchy statistic from those packets being analyzed. Based on the analysis of TCP stream excerpt and the protocols hierarchy statistic, the communication pattern between bot, botmaster, and infected host are known. Wireshark could show the data inside the TCP stream excerpt and all captured protocols. The conducted analysis on TCP stream excerpt and protocols hierarchy statistic is based on RFC 2812 (Internet Relay Chat: Client Protocol – IETF Tools). The analysis on TCP stream excerpt and protocols hierarchy statistic yield botnet activity information for the next step of the analysis of botnet attack, which is dataset and prediction model building. The prediction model can then be implemented to predict whether network traffic is safe or harmful.       Keywords: botnet, COMODO internet security, Internet Relay Chat (IRC), RFC 2812, Wireshar

A WebRTC Video Chat Implementation Within the Yioop Search Engine

Web real-time communication (abbreviated as WebRTC) is one of the latest Web application technologies that allows voice, video, and data to work collectively in a browser without a need for third-party plugins or proprietary software installation. When two browsers from different locations communicate with each other, they must know how to locate each other, bypass security and firewall protections, and transmit all multimedia communications in real time. This project not only illustrates how WebRTC technology works but also walks through a real example of video chat-style application. The application communicates between two remote users using WebSocket and the data encryption algorithm specified in WebRTC technology. This project concludes with a description of the WebRTC video chat application’s implementation in Yioop.com, a PHP-based internet search engine

Students and instant messaging: a survey of current use and demands for higher education

Instant messaging (IM) is the term used to describe the technology through which ‘users can set up a list of partners who will be able to receive notes that pop up on their screens the moment one of them writes and hits the send button’. While early use could be described as mainly for fun, IM today is a serious communication medium. Remarkably, it seems that educational institutions have been doing very little with it, while several studies indicate that it could indeed be a valuable tool in education. As a first step towards a better understanding of the educational use of IM, we want to gain insights in how students currently use IM and what opportunities they themselves see for the medium. To that end we conducted a survey among students of the Fontys University of Applied Sciences in The Netherlands. A large majority of the participating students indicated using IM for their studies. Also, when asked about their demands for a possible educational implementation, the majority were positive
