Broadband Convergence Network (BcN) can provide a range of quality guaranteed broadband multimedia services through packet-based converged transport network. For providing new emerging application services in due season over BcN, it is important for network designers or planners to develop a new design methodology for BcN, which differs from legacy design processes applied to a single service network. This paper thus introduces a new design concept and detailed design processes for KT-BcN. We also present a design example of BcN control network using a design system that we have developed.

최근 많은 TV방송사들은 다채널의 경쟁에서 우위를 지키기 위해 채널브랜드 전략의 일환으로 네트워크디자인(Network Design)에 매우 높은 관심을 가지고 있다. 네트워크디자인이 1997년 국내에 도입된 이래 주요 케이블채널 및 위성채널들은 앞 다투어 네트워크디자인을 방송에 반영하기 시작했다. 그러나 그 연구와 정보가 부족한 이유로 현장의 네트워크디자인 제작은 많은 어려움을 안고 있다. 성공적인 네트워크디자인 실행을 위해서 스타일가이드는 일관된 기획 및 구체적인 제작을 위한 필수적인 과정으로 매우 중요하게 인식되고 있다. 본 논문은 TV채널 이미지 제고를 위한 네트워크디자인의 이론적 체계를 마련하고자 네트워크디자인 스타일가이드를 연구하였다. 먼저 네트워크디자인 개념과 네트워크디자인 스타일가이드의 필요성을 논하였다. 그 다음, 네트워크디자인 스타일가이드의 사례연구를 통하여 주요 구성요소를 체계화하였고 각 요소의 개념을 정의하였다.

This paper describe the optimal design of geodetic network by analytical technique based on the quality criteria of network. We described an example of geodetic network design taking into account the precision, reliability and strength that are the main criteria of network design. The main goal of this paper is to evaluate the criteria to design the geodetic network coinciding with the criteria of geometrical strength and high reliability. From this study, the result shows relatively weaker strength in marginal part than the center of network. This indicated that the precision of observation in marginal part is relatively lower than the center.

This paper highlights new IP network design and internetworking scenarios overlayed on the existing ATM technology network. It describes the proper network configurations to solve the IP/ATM internetworking probrems on the AISN(Advanced Information Superhighway Network). The paper outlines that IP network can be constructed on ATM backbone network. The paper looks at how new design technology is to enhance the AISN in Korea. The paper concludes that new IP network design is applied to AISN and there is enough possibility that AISN can be developed to efficient NGI(Next Generation Internet).

Low earth orbit (LEO) satellite broadband network is a crucial part of the space information network. LEO satellite constellation design is a top-level design, which plays a decisive role in the overall performance of the LEO satellite network. However, the existing works on constellation design mainly focus on the coverage criterion and rarely take network performance into the design process. In this article, we develop a unified framework for constellation optimization design in LEO satellite broadband networks. Several design criteria including network performance and coverage capability are combined into the design process. Firstly, the quality of service (QoS) metrics is presented to evaluate the performance of the LEO satellite broadband network. Also, we propose a network stability model for the rapid change of the satellite network topology. Besides, a mathematical model of constellation optimization design is formulated by considering the network cost-efficiency and stability. Then, an optimization algorithm based on non-dominated sorting genetic algorithm-II (NSGA-II) is provided for the problem of constellation design. Finally, the proposed method is further evaluated through numerical simulations. Simulation results validate the proposed method and show that it is an efficient and effective approach for solving the problem of constellation design in LEO satellite broadband networks.

Concurrent Engineering (CE) is a popular method employed in product development. It treats the whole product design process by the consideration of product quality, cost, rate of progress, and demands of customers. The development of computer and network technologies provides a strong support to the realization of CE in practice. Aiming at the characteristics of CE and network collaborative design, this paper built network collaborative design system frame. Through the analysis of the network collaborative design modes based on CE, this paper provided a novel network collaborative design integration model. This model can integrate the product design information, design process, and knowledge. Intelligent collaboration was considered in the proposed model. The study showed that the proposed model considered main factors such as information, knowledge, and design process in collaborative design. It has potential application in CE fields.

This paper aims at the problem that design the network of Rig-star type with the minimum cost, which the Ring is composed of the selected nodes(concentrators) among the several candidate nodes on the network and other nodes(terminals) is connected to the Ring by star subnetwork. Especially, we consider the terminal reliability in network design problem. We develop the heuristic algorithm for network design problem to obtain the near optimal(best) solution for problem. We use an add-heuristic method and 2-exchange method in developing the heuristic algorithm.

The WK-recursive network proposed by Vecchia and Sanges[1] is widely used in the design and implementation of local area networks and parallel processing architectures. It provides a high degree of regularity and scalability, which conform well to a design and realization of distributed systems involving a large number of computing elements. In this paper, the routing of a message is investigated on the WK-recursive network, which is key to the performance of this network. We present an efficient shortest path algorithm on the WK-recursive network, which is simpler than Chen and Duh[2] in terms of design complexity.

The purpose of this study is to suggest an effective fashion design process using social network services(SNS) as a method to develop designs. Fashion design process was systemized through literature study. The characteristics of social network, and element and method of network formation were investigated, and then design processes using SNS were suggested through survey study. This was done by applying formation of network and its method in SNS with contents of fashion to stage of process to develop fashion design. The study results are as follows. First, Fashion design process using SNS is composed of 5 stages. Second, SNS types with contents of fashion were classified to five types: blog, community, connection of fashion web service and SNS, fashion SNS, and fashion SNS game. Among them, types where development of fashion design and product distribution was done by formation of network are connected type of fashion web service and SNS, fashion SNS type. Fashion design development can be done by compiling, having contests, and cooperative work. A method that can be used for making assessments and decision is voting and predicting the market. Third, Fashion design process using SNS is composed of the stages such as planning, compiling, analysis, decision, implementation, and formation of network. It was analyzed that by connecting stages of collection and evaluation of information through participation of users, new contents were produced and there was a structure that was cycled continuously.

An optimizer has been applied for the optimal design of pipe diameters in the pipe flow network problems. Pipe network flow analysis, which is developed separately, is performed within the interface for the optimization algorithm. A pipe network is chosen for the test, and optimizer GenOpt is applied with Holder-Mead-O'Niell's simplex algorithm after solving the network flow problem by the Newton-Raphson method. As a result, optimally do-signed pipe diameters are successfully obtained which minimize the total design cost. Design cost of pipe flow network can be considered as the sum of pipe installation cost and pump operation cost. In this study, a practical and efficient solution method for the pipe network optimization is presented. Test system is solved for the demonstration of the present optimization technique.
