  • Gigabit Ethernet was advented as Internet's activation from owing to Internet user and the development of its various application and as inevitability the high-speed network as its demand for more and more the bandwidth by much application using the network. This Gigabit Ethernet makes an alternative plan to solve the request traffic by Internet user, because it holds several merits as providing great capacity with the network in the existing Ethernet environment and as displaying highly efficient ability This paper researches into a concept and characters about Gigabit Ethernet technology and raises the stability and efficiency of Gigabit Ethernet with regard of competing against FDDI technology and using Traffic analysis.

  • This paper describes the implementation of an internet-based servo-control system with novel direct internet control architecture which is insensitive to the inherent internet time delay. The servo control system can be controlled by using a PC provided at a local site. However, a large internet time delay may make some control inputs distorted. Moreover, since it is acted by the number of the internet nodes and loads, this delay is variable and unpredictable. This system consists of servo mechanism and Ethernet control adapter. Intention of this paper is to reduce the expenses, to manage effectively for plant and to increase the productivity through linking each plant of several factories by TCP/IP and Ethernet, and then many control plants and manager minimize the needed work. Experiments are partially fulfilled using the Labview and Matlab.

  • Nowaday, the wideband multimedia service, high speed and great capacity internet service etc. are increasing, so the network construction with the base of optical subscriber network is necessary. As efficient and economic optical subscriber networks are developed, so efficient network construction is possible. The most technology of them is WDM(Wavelength Division Multiplexing)-PON technology of ONU(Optical Network Unit) jointing method using PON(Passive Optical Network). In this paper, we have studied on a method for automatic optimization of data modulation current as optical power when the data is transmitted.

  • Based on the rapid development of IT technology and deployment of the Internet through high speed networks, network environments have been changed from office oriented environment based on business industries and public institution even to the interconnection to digital electronics in the home network. Home network based applications are very diverse and the remote monitoring and control areas have been studied. In this paper, we present the design and implementation of real time remote video monitoring system which provide the moving pictures on the web page through the Internet using JMFI. In addition, we present the design of remote light control system based on Zigbee.

  • As to the recent advances in computer technologies and high-speed networks, telecommunication services and provision of multimedia services will be provided on the basic of a new software architecture adapting networking infrastructure on open information networking architecture. In this paper, the video conference services has been selected as a target service example because it is expected to become one of the most important services on the full service network. In fact, it can be viewed as the basis for providing telecommunication services such as video telephony and video conferencing. This paper presents the prototyping of TINA (Telecommunication Information Networking Architecture) based desktop video conference system using the concepts of session management. The prototyping of desktop video conference system aims at assessing TINA concepts and refinement of the mapping between session graph and connection graph, and provides object modeling methodologies towards distribution and objected-orientation.

  • The Internet is emerging as a powerful tool in the area of information and communication technology. The WWW has been especially contributed to increase the internet demand because of its browser which has "Graphic User Interface". Nowadays number of hosts that supply harmful information such as pornographic materials, and the infringement of human rights is rapidly increased. Access to such materials is very easy. Therefore security system which will protect young users from access to harmful host is needed. This paper presents implementation of user system has database about harmful hosts at the Internet and monitors that the user traffic over LAM get touch with the hosts. The system can not make the user access the harmful host because it can over LAN. The performance analysis on the developed system monitoring the traffic over LAN of Andong university is carried out. The performance analysis of monitoring results satisfies with preventing users from the connection to the internet harmful sites.
