The Design And Implementation Of A Conference System Based On Next Generation Network

Objectives of Session Initiation Protocol are based on point-to-point Internet connections which been commonly used to control the session with a sound mechanism for the meeting to support the deployment of the system. The meeting has been developed with the rapid growth on computer processing power, storage technology, compression algorithms and network technology. As the generation network, Session Initiation Protocol provides multimedia services and unique advantages. Session Initiation Protocol is a considerable and promising technology for signaling control protocol which would play an important role in next generation network applications. The centralized control of web conferencing systems based on Session Initiation Protocol conform to the hierarchical model of thinking, better reflects the system's flexibility and manageability, provide reference value on the Session Initiation Protocol development and application. Session Initiation Protocol is designed basing on Internet standards and reflecting the application of Internet protocol design principles and against characteristics of the H.323 protocol. Its centrally controlled entity enables the realization of the meeting and the application of the Multipoint Control Unit entity.Currently, the H.323 protocol-based network conferencing systems have been wildly used. H.323 protocol provides an older, more complex with less flexibility and openness. Web conferencing systems are built on the internet, which can be easily integrated with other Internet application services and provide a variety of formsand personalized service for users. Session Initiation Protocol is a new multi-media connection session control protocol, which could well-compatible with voice, video, data, text, and outlines its value in next generation network business. The conferencing systems based on Session Initiation Protocol is is also very convenient to intergrate with the next generation of network with other multimedia services. Session Initiation Protocol conferencing systems is based on IP network which could only provide unreliable quality of service. However, this can be improved by combining IP network service quality assurance mechanisms , such as RSVP . Session Initiation Protocol is a good system with openness, a wealth of expressions, and thus suitable for low-cost internet provider and a loose group of communication services. Session Initiation Protocol system is limited by lower main transmission network in the management.In an IP network with quality assurance server, the Session Initiation Protocol conferencing systems provide many features, manageability and low cost of meeting services.This article elaborated on the platform features Session Initiation Protocol Web conferencing systems design and realization of prototypes to study the design of a centralized multi-media session control mechanism to achieve a flexible multi-session between the management and control. Papers from the main mode of control framework and processes in areas such as signaling for a number of studies. Combination mode of the meeting, in line with the requirements of the development of the centralized control of the framework of the meeting, on the basis of the design, C + + language developed Session Initiation Protocol features meeting and conference application server platform. In the test environment for the meeting, the two modes of operation tests to verify the correctness of the entire system design; it with the traditional way of meeting system has many advantages compared to the same time, there are some shortcomings, the paper put forward by the conversation .The initial agreement is a model of Web conferencing systems based entirely on the softswitch, and the traditional network-based conferencing systems are integrated hardware board, traditional web conferencing system costs are high, binding to a specific hardware vendor's shortcomings. In comparison, the Session Initiation Protocol-based network conferencing systems have the advantages of low cost, and from architecture to achieve point of view, the Session Initiation Protocol web conferencing system built on a common platform functions, and form a meeting with business logic Coupled with the underlying control features, making Session Initiation Protocol network conferencing business logic to achieve modular design, and easy to maintain and expand.It also adopted the current IETF's Session Initiation Protocol hybrid model and the model framework for an in-depth analysis, operation and management set for the meeting will be tightly coupled system of the meeting focused on the mixed-mode model, are discussed in detail the structure of the model design and prototyping To achieve. The system primarily through the Session Initiation Protocol session control server to achieve session of the call control, media server meeting of the members of the media stream of mixed distribution, the meeting of the Conference on the management of server management. In this paper, through the work of the show based on the Session Initiation Protocol to build a management system can be operated by the meeting, and basically meet the requirements of small and medium-sized meeting.The next Generation Network metting is based on a remote interactive communication system combining voice, images, text and other information . . It applies to wide range of applications and shows good development prospects. Session Initiation Protocol provides a general conversation control mechanism and various design, whose basic agreement could achieve a manageable, centralized conference system control. At present, IETF has provided a large number of draft standards to meet the Session Initiation Protocol Conference System. Meanwhile, good scalability of Session Initiation Protocol ensure its brighter future..
