Trade Portal Site(TPS) is one of the essential tools which can make it possible for small and medium enterprises(SMEs) to perform international trade activity more efficiently using newest information and communication technology including the Internet. Therefore, Korean SMEs need to utilize TPS more actively to enhance their export competitiveness. In this context, this article analyzes the determinants of export performances of Korean SMEs in utilizing the service of TPS based on the Service Quality Model. As a result of an empirical research by using regressive analysis, various measures of service reliability such as reliability, empathy, and tangibilities have positive effects on SMEs export performance in utilizing TPS. These results provides many useful implications to the TPS managers, e-trade related government agency, along with managers of SMEs using TPS.

In this paper, we address TPS (Triple Play Service) based on E-PON and also develop QoS control function for both directions, which is disadvantage of E-PON. E-PON technology has the configuration suitable for TPS, but relatively the large delay characteristics in upstream, so if QoS control function must be supported to transfer the real time traffic for both directions, E-PON technology can support TPS efficiently. Therefore, in this paper, we address the diverse requirements of quality for TPS, and then develop TPS platform to verify the quality characteristics according to QoS characteristics of each element in real environment based on this. This result will be used to improve the quality of TPS that become conventional in near future. ISP will use this result as the basis in establishing quality reference and as the guidance in developing new system.

논문은 LG 데이콤의 TPS 서비스에서 사용되는 여러 단말의 초기 설치의 편의성을 최대한 보장하기 위한 자동 프로비저닝 시스템에 대한 연구이다. 이를 위해서 요구되는 단말기의 식별자와 암호화를 처리하기 위한 자동 프로비저닝 시스템의 수행 절차를 제안한다. 기본 구성은 홈게이트웨이를 이용한 홈네트워크를 구성하고 있다. 이를 기반으로 하여 IPTV 셋탑, WiFI 폰, PC 를 동시에 사용하기 위해서는 자동 프로비저닝 시스템에서 여러 단말기로 네트워크 접속에 필요한 정보(접속할 시스템의 주소(IP), 포트 및 환경 파일)를 전송하거나, 단말기가 직접 다운받을 수 있도록 한다. 이를 제공하는 시스템을 TPS 자동 프로비저닝 시스템이라 명하며, 이는 가입자의 개입없이 홈네트워크 환경과 멀티미어어 서비스 환경을 자동으로 설치함으로써 사용자의 편이성을 극대화하게 된다. 본 논문은 TPS 서비스와 디지털 홈 서비스의 근간이 되는 프로비저닝 플랫폼의 기술적 가능성을 검증함으로써 향후 관련 단말기 개발 및 개방형 서비스를 제공하기 위한 기초자료로 활용되고자 한다.

In this paper we propose a QoS policy, which is based on both DSCP and SPQ, appropriate to TPS users on optical subscriber network. Then we experiment and evaluate QoS policy through the test bed which emulates real optical subscriber network. In order to perform effective and real experiment on test bed we make test traffic equivalent to 400 TPS users and give it to test bed. The experimental result shows that no packet loss in real time service traffic such as voice, IPTV occurs during more than 4 hours. We think that our proposed QoS policy is a proper method which guarantees the service quality of real time services on optical subscriber network.

Recently, broadband access networks have been competitively deployed all over the world with the development of various multimedia services for such a network. ETRI(Electronics and Telecommunications Research Institute) built the FTTH(Fiber-To-the-Home) service center to develop a next-generation equipment and a high-quality service/platform as well as to promote domestic industry in the field of optical communication. The FTTH service center has a variety of test equipments such as FTTH standard testbed for a BMT(bench mark test), a network operation center, and IPTV service equipments. Also, ETRI deployed a new type of commercial optical access networks cooperating with ISP(Internet Service Provider). This paper presents the performance evaluation of FTTH E-PON(Ethernet Passive Optical Network) system as a platform for TPS(Triple Play Service) based on QoS(Quality of Service) and QoE(Quality of Expericence) issues. This FTTH E-PON system is successfully demonstrated as an optical access network system by commercial network service provider and the FTTH service center of ETRI.

IPTV is well known services of TPS (Triple play service). Since TPS supplies the bundle service, service providers can supply low-priced services for their subscribers. To supply high quality contents stably, it is an essential requirement to make payment for the services. According to the type of services, either CAS or DRM is used to protect the pay-contents service. Also IPTV uses or will use these security systems to protect the service. In this paper, we will describe security problems when a IPTV service provider chooses either CAS or DRM, and then propose a new security system to solve the problems.

The internet has dramatically changed a way of business management and competition in the business environment. Especially, it stimulated not only to evolve online floral distribution service but also to change a phase of competition among floral retail stores in industry. And that also led to keen competition among IT service providers as well. This study is to examine how floral retail stores have been evolved and competed with the radical situation of the floral distribution industry through IT service in the aspect of business and information technology. In addition, the Typhoon Positioning Strategy(TPS), a strategy for the IT service positioning, is introduced from IT service provider's perspective. For IT service providers to create high business value and continuous service providing, IT service should be positioned on the customers' "core business" and developed to the level of "solution." The Typhoon Positioning Strategy(TPS) is a strategy for the IT service positioning, indicating that IT service should be positioned according to a Business Process-Service model with the consideration of business development direction, IT service trend, and user's IT capability. That is, IT service providers should find out customers' "core business" area first to provide a right IT service to the company, and the IT service provided should meet to the level of business solution. The capability of the IT solution users is also an important factor to be considered for the advanced IT service. There are four principles of the Typhoon Positioning Strategy(TPS). Principle 1) IT service provided should be an IT solution Map suitable for customer business processes. Principle 2) IT service provided should be able to support customer core business. Principle 3) IT service provided should be a business solution. Principle. 4) IT service provided should be applied differently according to the level of customer's IT capability.

현재 통신 시장은 보다 편리하고 다양한 서비스를 찾는 소비자의 욕구와 맞물려 TPS(Triple Play Service) 방향으로 급속히 나아가고 있다. 인터넷 전화의 보급은 이미 보편적 서비스가 된 초고속인터넷 서비스와 연계하여 빠르게 확산되고 있으며, 2007년 들어 방송서비스까지 결합한 TPS에 대한 통신사업자간 경쟁이 본격화되고 있는 추세이다. 트리플 플레이 서비스(Triple Play Service;이하 TPS)는 초고속 인터넷과 인터넷 전화와 방송 서비스를 하나의 회선으로 제공하는 종합 인터넷 서비스로, 광대역 통합망(BcN; Broadband Convergence Network)의 핵심 서비스이다. 액세스 스위치(Access Switch) 단은 TPS로 인해 더욱 많은 역할을 담당할 것으로 전망되는데, 디지털 방송을 인터넷 프로토콜을 통해 전송하기 위한 멀티캐스트 기능과 혼재된 이종간의 디지털 신호를 각 서비스의 품질에 맞게 보장해 주는 QoS(Quality of Service) 기능이 무엇보다 중요하게 고려 되어야 한다. 본 논문에서는 TPS의 핵심일 수 있는 방송 서비스를 위해 액세스 스위치 단에서 제공해야 할 멀티캐스트와 QoS 기능 구현 방안에 대해 제시한다
