Various types of B-ISDN bearer connection can take place according to access types of endpoint equipments in call and number of connectio between endpoints. In this paper, performance of application signalling protocol on three basic facilities of B-ISDN CS-2 signalling system, such as connection of point-to-point, point-to-multipoint and multiconnection call, is evaluated and compared. For performacne evaluation, experimental model of B-ISDN application signalling protocol is implemented and respective message processing time of each process is measured. By applying message processing time to local exchange system, cal processing capacity of application signalling protocol on three basic connection types is evaluated by simulation method. In this paper, local exchange system is considered to have two ATM NNI links and four ATM UNI links.

These days, interest and demand on smart learning has rapidly increased. Video English and mobile system based English speaking service have become popular. This study gave prototype of application to give and take voice message with world people and to give new concept of voice pen-pal beyond exchange of text messages. In modern society having rapidly increasing demand on smart learning, you can study foreign language by smart phone and communicate with foreigners by voice anytime and anywhere. The app allows global exchange to learn conversation. Recruitment of initial users and profit model have problems. We shall develop to improve problems and to solve difficulty.

In this paper we researched on the development methods and design of the B-ISDN protocol embedded Internet-Phone PBX System for the previous telephone exchange and communication. We designed the structure of the user terminal md exchange server of the Internet-Phone PBX System, defined message and data structure for call control, and designed call control message flows between sender and receiver terminal for user's communication.

The SECS(SEMI Equipment Communications Standard) is a standard protocol for communication between equipments and a host in semiconductor processes. This paper proposes the implementation of the HSMS(High-speed SECS Message Services) as an interface for transmission of the SECS messages and SECS-II containing message contents defined as an SEMI standard. The HSMS driver is implemented as a type of the daemon program and several DLL files. The SECS-II composes of the SML(SECS Message Language) file defining the SECS messages, the SML translator being able to interpret and transform the SML, and the data index table being able to refer to SECS messages. We also define the shared parameter to exchange the HSMS header and SECS message between the HSMS and the SECS-II. Eventually, to show the effectiveness of the proposed drivers, we test the SECS communications between equipments and a host using the implemented communication programs.

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

This study set out to developing data exchange standard between roadside device and traffic information center fitted in a domestic environment by applying international standard ISO 15784. First, we defined message basic concept of 'Dialog' and essential elements should be defined to define the standard message for securing system compatibility by reference ISO 14817 and ISO 14827 Part 1. For defining standard message items exchanged between AVI and traffic information center, we formed Working Group under ITS Standards Technical Committee and analyzed data flow for ITS National Architecture, Standard messages of existing standards, and AVI operation messages actually operated on roadside now. So, we extracted 14 functionally needed messages and defined 28 standard messages adopting 'Dialog' concept. In case of the application protocol for data exchange standards, we defined basic requirements for securing interoperability and interchangeability considering domestic environment by analyzing reference standard of ISO 15784.

The Army, Navy, and Air Force are making various efforts to develop a weapon system that incorporates the 4th industrial revolution technology so that it can be used in multi-domain operations. In order to effectively demonstrate the integrated combat power through the weapon system to which the new technology is applied, it is necessary to establish a network environment in which each weapon system can transmit and receive information smoothly. For this, it is essential to analyze the Information Exchange Requirement(IER) of each weapon system, but many IER analysis studies did not sufficiently reflect the various considerations of the actual tactical network. Therefore, this study closely analyzes the research methods and results of the existing information exchange requirements analysis studies. In IER analysis, the size of the message itself, the size of the network protocol header, the transmission/reception structure of the tactical network, the information distribution process, and the message occurrence frequency. In order to be able to use it for future IER prediction, we present a technique for calculating the information exchange requirement as a probability distribution using the Poisson distribution and the probability generating function. In order to prove the validity of this technique, the results of the probability distribution calculation using the message list and network topology samples are compared with the simulation results using Network Simulator 2.

Password authenticated key exchange (PAKE) is a protocol that a client stores its password to a server, authenticates itself using its password and shares a session key with the server. In multi-server PAKE, a client splits its password and stores them to several servers separately. Unless all the servers are compromised, client's password will not be disclosed in the multi-server setting. In attribute-based encryption (ABE), a sender encrypts a message M using a set of attributes and then a receiver decrypts it using the same set of attributes. In this paper, we introduce multi-server PAKE protocol that utilizes a set of attributes of ABE as a client's password. In the protocol, the client and servers do not need to create additional public/private key pairs because the password is used as a set of public keys. Also, the client and the servers exchange only one round-trip message per server. The protocol is secure against dictionary attacks. We prove our system is secure in a proposed threat model. Finally we show feasibility through evaluating the execution time of the protocol.

Server push which is technology of sending contents from servers to browsers in real time using long polling requests enables real time bidirectional communications between servers and browsers in HTTP environment. Recently, thanks to the rapid supply of mobile devices having ability of full browsing, server push is being applied to various applications. However, because servers providing services should offer distributed contents to a large number of users simultaneously in various user environments, they have a burden that offers contents quickly distinguishing much more concurrent users than before. The method of message exchange so far achieved in distributed server environment has difficulties in the performance of simultaneous user request process, the identification of users and the contents delivery. In this paper, We proposed message exchange architecture between servers for offering server push in the distributed server environment. The proposed architecture enables message exchange in the method of push between servers based on event driven architecture. In addition, the proposed architecture enables flexible identification of a event agent and event processing under the connected environment of a lot of users. In this paper, we designed and implemented the proposed architecture and compared performance with the previous way through a performance test. In addition, function is confirmed through the case realization. As a result of the performance test, the proposed architecture can lessen the use of server Thread and response time of users and increase simultaneous throughput.
