최근 네트워크 환경은 광대역화 되고 있고, VOD 서비스를 제공받는 사용자의 단말기들은 용도나 취향에 따라 다양화 되고 있다. 기존의 NVOD 서비스들은 단말기에 일정 저장 공간을 요구하거나 단말기의 네트워크 전송률은 고려하지 않았다. 본 논문에서는 광대역통합망에서 다양한 단말기의 저장 공간과 네트워크 전송률에 따라 적응가능한 NVOD 서비스방법을 제안한다. 따라서 제안된 방법을 이용해서 필요에 따라 다양한 환경의 단말기를 개발할 수 있고, 모든 단말환경에 적용할 수 있기 때문에 활용도가 매우 높을 것으로 기대된다.

In this paper, we propose a real-tim measurement management system UI development linked the Water treatment facilities broadband Convergence Network. The sensor and the image data received by the server develop a program to interact with Web through water treatment facilities broadband convergence network. So, Separately develop UI capable of independently operating. Building a web server for remote monitoring of the transmission sensor and the image data. And Monitoring and control is possible the sensor data and image data through the Web-based UI. We can grasp the current state such as measurement time, concentration and depth of interface through the proposed real-time measurement management system UI development liked the water treatment facilities broadband convergence network. So, we can check in whether the normal operation of water treatment facilities and whether the casualties such as fire and security. As well as real time to see the information at a glance due to UI development can be raal-time monitoring of real-time measurement management system.

최근 정보통신 환경은 통신, 방송, 인터넷이 통합되는 디지털 융합 서비스 제공 형태로 급속히 변화하고 있다. 이에 따라 통신환경이 개방형 네트워크 형태의 광대역통합망으로 변화하였다. 이런 광대역 통합망에서는 Open API(Application Program Interface)에 의하여 third-party 애플리케이션의 제공을 가능하게 한다. Open API에는 대표적으로 Parlay API가 있으며 Parlay API와 웹 서비스를 접목시키고 한단계 더 추상화한 Parlay X API가 있다. 웹 서비스의 요소중의 하나인 UDDI는 웹 서비스를 쉽게 검색, 공유 및 재사용 할 수 있도록 하는 환경을 가져오게 된다. 본 논문에서는 웹서비스기반의 개방형서비스 게이트웨이를 위한 효율적인 UDDI 레지스트리 구축방안에 대해 제안하였다.

The billing manabement techniques for multiple services in the B-ISDN network have been rarely developed. In fact, the management techniques including billing manabement only focus on a single service environment. In this paper, we propose a billing management system architecture for the multiple services in a Broadband access network. The architecture is based in OSI system management infrastruture and TMN Q3 interface to exchange and process the billing information from access node that is an ATM Cross connecter. The system is designed to actively adopt the rapidly changing service environments and B-ISDN network management techniques. Futhermore, this system supports multiple services providers by real-time collector and charging functions for their requirements compared to the previous methodologies tat only use the statistical data.

Recently, environment facilities are able to manage real-time data collection and record management through integrated broadband modem LAN switching technology. Therefore, it need more stable and efficient facility management. So, we required practical use of environmental facilities convergence based on broadband integrated modem. In this paper, we proposed an integrated broadband modem LAN switching technology which can applicable to the environment facility. Also, we presented integrated broadband modem of design plan and communication system. And it received data inside of environment facility using the two communication methods(IEEE802.11x and IEEE802.15.4x). Then, our proposed integrated broadband modem LAN switching technology will prioritize processing data when emergency happen through collecting data, analysis data and processing. Lastly, we proved usefulness by experiment and simulation analysis.

Broadband Convergence Network (BcN) is the network which unifies telephone network, the Internet and broadcasting networks. Threats to each network can bring serious problems in BcN environment since the whole network can be damaged by various types of attack. The purpose of this study is to suggest the prototype of intrusion-tolerant network design of BcN to guarantee the continuous operation of BcN services against malicious attacks. First, BcN service components, selected by analysis of service time and coverage importance, are classified into three groups by their type: server type, gateway type and hybrid type. Second, the necessity of applying intrusion tolerance on BcN services is deduced by possible attack scenarios on BcN. Finally, we suggest the intrusion-tolerant network design suitable to BcN, using hardware redundancy and secure policies. Also, we present that the suggested network design can increase the intrusion tolerance of BcN.
