SOAP is a protocol used for information exchange in distributed computing environment and SOAP defines mechanisms for message transferring between distributed system and remote procedure call/response process. This SOAP is able to be used independently on operating systems and program languages because it uses only a text-based XML for protocol. Therefor ebXML that is a standard for E-Commerce adopts SOAP for message exchange. In this paper, we developed Message Broker System based on SOAP. By this Message Broker System we can more easily exchange messages for B2B. Accordingly we can manage and integrate a lots of business partners.

XML message brokers have a lot of importance because XML has become a practical standard for data exchange in many applications. Message brokers covered in this document store many users. This paper is a study of the processing of twig pattern queries in XML documents using branching node streams in XML message broker structures. This work is about query processing in XML documents, especially for query processing with XML twig patterns in the XML message broker structure and proposed a method to reduce query processing time when parsing documents with XML twig patterns by processing information. In this paper, the twig pattern query processing method of documents using the branching node stream removes the twigging value of the branch node that does not include the labeling value of the branch node stream when it receives a twig query from the client. In this paper, the leaf node discovery time can be reduced by reducing the navigation time of nodes in XML documents that are matched to leaf nodes in twig queries for client twig queries. Overall, the overall processing time to respond to queries is reduced, allowing for rapid question-answer processing.

SOAP(Simple Object Access Protocol)은 분산 환경에서의 정보 교환에 사용되는 분산 컴퓨팅 프로토콜로 분산 시스템간에 메시지를 전달하는 방법, 원격 프로시저 호출／응답을 처리하는 방법이 정의하고 있다. 이러한 SOAP 는 텍스트 기반 XML을 프로토콜로 사용하고 있기 때문에 하드웨어 플렛폼, 운영체제, 프로그래밍 언어에 독립적으로 사용할 수 있다. 이러한 이유 때문에 전자상거래 표준인 ebXML 에서도 메시지 전송을 위해 SOAP을사용하고 있다. 본 논문에서 SOAP을 기반으로 한 메지지 Broker 시스템을 구현하였다. Broker 시스템을 통한 메시지 전송으로 많은 비즈니스 파트너를 통합관리 할 수 있을 것이다.

The Tunnel Broker is to provide dedicated servers and to automatically manage tunnel requests coming from the users. This approach is useful to stimulate the growth of IPv6 interconnected hosts and to provide easy access to their IPv6 networks. However, the existing tunnel broker is vulnerable to attacks of malicious users about network resources and services. Therefore, to solve the secure problem of tunnel broker, this paper presents secure IPv6 tunnel broker based on TSP(Tunnel Setup Protocol). The clients and the tunnel broker are communicated based on SHTTP(Secure HTTP) and the XML message of plain text is converted to XML signature by encryption and decryption. finally, Clients and tunnel server use the IPsec method to protect the important information.
