Multicast protocols are efficient methods of group communication such as video conference, Internet broadcasting and On-Line Game, but they do not support the various transmission protocol services like a reliability guarantee, FTP, or Telnet that TCPs do. The Purpose or this Paper is to find a method to utilize multicast routers can simultaneously transport multicast packets and TCP packets. For multicast network scalability and error recovery the existing SRM(Scalable Reliable Multicast)method has been used. Three packets per TCP transmission control window site are used for transport and an ACK is used for flow control. A CBR(Constant Bit Rate) and a SRM is used for UDP traffic control. Divided on whether a UDP multicast packet and TCP unicast packet is used simultaneously or only a UDP multicast packet transport is used, the multicast receiver with the longest delay is measured on the number of packets and its data receiving rate. It can be seen that the UDP packet and the TCP's IP packet can be simultaneously used in a server router.

'Jump' control is one of several game controls using mainly in 2D game, and 'Jump' control is also very important in 3D game that has been developed steadily due to the advance of programing technology. 3D MMORPG among some kinds of 3D games is the most popular as on-line game in domestic game market these days. This study will give domestic game developers ideas and solutions through analyzing and testing problems caused by applying 'Jump' control technique as control interface of 3D MMORPG game.

Game program manufacture had been classed by 3D or on-line game etc. simply. But, atomized game programmer's kind now. So, Artificial Intelligence game programmer's role is important. This paper used reinforcement learning algorithm for Jul_Gonu board characters to learn, and so they can move intelligently. To compare a learned character to an random one, a board game was created, and then they fought against each other. As a result, learned character‘s ability was far more improved.

An on-line game is growing of very fast through characters of the interactive Computing and internet environment. In addition, an edu-game combing the advantages of the game and the education increase gradually. The paper proposes an edu-game system for providing knowledge through the hierarchical structure. The system differs from existing ones that combine a game and an on-line education. There are three different goals as follows. First, the paper proposes three-level of knowledge hierarchies. The method enables users to understand more easy and systematic and interesting education. Second, the graphic interface of a puzzle type is able to contact more conveniently and it provides beauties and functionalities. Third, Among them, specifically the knowledge hierarchy is not forced to users and the method also can study in detail and users can enjoy systematically e-education by using the general type of a puzzle game.

The object of this research is to analyze the impact of the four dimensions of on-line game attributes, challenge, social interaction, entertainment and actuality, on customer satisfaction and loyalty. At the same time, mediating effects of switching barriers, such as switching cost and attractiveness of alternatives on the relationships between customer satisfaction and customer loyalty are also analyzed. The results showed that the challenge, social interaction, entertainment had significant effects on customer satisfaction. Customer satisfaction also effected customer loyalty. Another important result is that switching cost and attractiveness of alternatives played an intermediating role between customer satisfaction and customer loyalty.

Difference of individual character is defined Cerebral Hemispheric Model(CHM) to develop individual intellectual abilities in this paper. Component of preferred online-game is surveyed in accordance with individual character, and investigated for possible applications. An individual is classified with 2 modes of CHM that take charge of intellectual abilities; abilities is character, taste, personality decision-making and behavior patterns; that is closely related to creativity. Difference of game component could be investigated with correlation table of cerebral preference patterns (CPP) that was drawn up with survey. Individual brain preferences (IBP) became clear through preference of individual in the investigation, and suggested concept guide-line to develop other brain preferences. Thus, this study is able to realize from education game to a great variety of contents that base on the development of thinking-faculties as optimization of user preference, can be the basic data of self-development, to improve intellectual faculties as development of individual thinking preference.

Recently, online-game industry has been rapidly expanding in these days. But, the various game service victimized cases are generated by the bots program. Particularly, the abnormal collection of the game money and item loses the inherent fun of a game. It reaches ultimately the definite bad effect to the game life cycle. In this paper, we propose a Bots detection method by observing the playing patterns of game characters with game log data. It analyzed behaviors of human players as well as bots and identified features to build the model to differentiate bots from human players. In an experiment, by using the served online-game, the model of a user and bots were generated was distinguished. And the reasonable result was confirmed.

Supporting the interactive relation between gamer and computer, and offering the game world information, the user interface in online games plays an important role for a gamer to lead game into the intended direction. The purpose of this study is to analyse a currently utilized online game with educational implications and to analyse its user interface design elements, in order to suggest the strategy how to reformative educational online games.

The purpose of this study is to analyze user-generated rules in online games and to define the way of players' identities are developed. This study focuses on the online game League of Legends, which originated from use map system. Based on rule theory, this study analyzes the characteristics of user-generated rules. As the result, this study proves that the main rule of online game is not the rules made by developers, but the emergent rules made by players. Through rule-detection and rule-selection process, user-generated rules change the game system. Therefore, the result of this study expects to show meaningful roles of players in game system.

In this paper we propose the methodology for 3D background image construction in computer games. This methodology was developed based on TIP (Tour Into the Picture) using a vanishing line Proposed by Kang et at. The methodology Proposed in this study can simply implement a 3D background for a computer game with a background model which is very complex or based on a real picture. Compared to the graphics technologies generally used, the proposed methodology does not need the process of modeling elaborate 3D information of a background, and hence can display the background even on a low grade personal computer using a small reference image. TIP technology was successfully applied to the implementation of a background model for a computer game and was found to be appropriate especially for real time games.
