Unified Communications: computer technology with traditional communication technologies

Unified communication means, the computer technology and traditional communication technology one of the new communication mode, both the integration of computer networks and the traditional communication network in a network platform, telephone, fax, data transmission, audio and video conferencing, call center, instant communication and many other application service. In the fusion of communication, the telephone network ( VoIP ) is one of the key. It is also called the "three networks convergence ". Triple play is a generalized, social view, at this stage, it does not mean that the telecommunication network, computer network and cable television network network physical one, but mainly refers to senior business application integration. The performance of technology convergence, network layer can achieve interoperability, to form a seamless coverage, the business layer of mutual penetration and cross, the application layer tends to use a unified IP protocol, in the operation of mutual competition, mutual cooperation, toward the human to provide diversified, multiple media, personalized service of the same target gradually converge, industry regulation and policy also tends gradually to unity. The big three network through technical transformation, to provide voice, data, image and multimedia communications business. This is the so-called triple play. Convergence, in concept from different angles and levels of analysis, can be related to the technology, business integration, industry, terminal and network fusion fusion fusion. At present, more important is the application of level to each other using an unified communication protocol. Optimization of IP optical network is a new generation telecommunication network based, is what we call the convergence of combination. The rapid development of digital technology and the comprehensive use of, make the call, and image signal data are available through the unified coding transmission and exchange, all operations in the network will become a unified "0 " or " 1 " bit stream. The development of optical communication technology, integrated delivery of various business information to provide the necessary bandwidth and transmission of high quality, become the ideal business platform network. The development of software technology makes the big three network and terminal through software changes, the final support for various user desired characteristics, functions and operations. The most important is the unified TCP/IP protocol widely used, will make all kinds of IP based on different online business can realize the intercommunication. The first human has uniform for the three network can receive the communication protocol, from a technical for the convergence of three networks laid the solid foundation. However, if according to the traditional approach to integration will be a long-term and arduous process, how to bypass the traditional networks to achieve fusion purpose, that is to find the revolution of telecommunication system of the road, we must grasp the development trend of the technology, combined with China's actual situation, to choose our own road of development. Our actual situation is data communication compared with the developed country starts late, the traditional data communication business size, compared with the developed countries, the protocol multi-service burden is much smaller, therefore, can be as soon as possible towards IP based system, using IP optimization in optical cable optical network, broadband IP network construction, the acceleration of China's Internet network development, and make the Chinese traditional communication network coexist for a long time, saving expenses and make full use of the existing cyber source.
