一、概述在这个信息化的时代,人们沟通日益频繁,所需用到的信息数量剧增、类型也多媒体化,如果没有这些海量的信息,人们仿佛没有了眼睛、耳朵等基本的感官;为了使网络能够更好地承载这些信息,更好地为大众提供各种通信业务和服务,我们对网络这个巨大的承载主体实行了不断的改造和升级,现在最热门NGN技术也正是旨在改造和升级网络。信息化是全社会的进步,包括电信运营商在内的各大行业,都产生了使用软交换技术的需求;但通常电信运营级的软交换规模很大,不适合在其它行业的中小规模应用。烽火科技针对行业用户的特点,开发了一系列软交换产品,以提供一整套面向行业用户的解决方案。烽火科技NetSwitch NGN行业用户解决方案是基于软交换技术构建,融合了数据、语音、视频等综合业务而提出的。该解决方案把企业的专网和公网连接了起来,企业使用IP技术可以将语音、数据和多媒体通信融合在一个集成的网络中,实现了广域网—局域网内端到端设备的互通。穿透NAT,既能控制 I. Overview In this era of informationization, people communicate more and more frequently, the amount of information needed increases sharply, and the type is also multimedia. Without such massive information, people seem to have no basic senses such as eyes and ears. In order to So that the network can better carry this information and better provide all kinds of communication services and services to the public. We have continuously transformed and upgraded the huge network hosting entity. Now the hottest NGN technology is also aimed at transforming And upgrade the network. Information technology is the progress of the whole society. The major industries including telecommunication operators all have the demand for using softswitch technology. However, the softswitch of telecom operators is usually of a large scale and is not suitable for small and medium-sized applications in other industries . According to the characteristics of industry users, FiberHome developed a series of softswitch products to provide a complete set of solutions for industry users. FiberHome NetSwitch NGN industry user solutions are based on softswitch technology to build, integration of data, voice, video and other integrated services put forward. The solution connects the corporate private network to the public network. Enterprises use IP technology to converge voice, data and multimedia communications in an integrated network, enabling end-to-end WAN / LAN interoperability. Through NAT, can control
