程控交换网络技术及智能云交换技术综述和展望

摘要

Withthe rapid development of modern switching technology in recent 20 years, the automatic control of voice data has been solved. However, the development of internet technology has brought new challenge to traditional switching network for the increasing complexity and bandwidth, which is the reason that the switching technology with capacity and data enhancementhas been raised. The utilization of digital highspeed switching technology has brought significant support to varieties of multimedia service and the ability of data transmission and service has been increased. In this work, we review the history of switchingtechnol-ogy in brief, and look ahead the future NGN switching network and intelligent switching network.%程控交换技术历经20余年的发展，解决了大容量自动化话务控制问题。然而随着互联网技术的发展，单纯的话务网络已经不能够满足日益增长的网络多样性和带宽需求的剧增，从而大容量智能交换以及大数据交换技术应运而生。利用数字高速交换技术，网络能够承载业务类型和业务量逐渐增大，为用户带来了极为丰富的多媒体服务。本文主要对程控交换网络的历史进行简要的回顾，并对当前具有发展前景的 NGN 智能网络技术以及大数据智能网络技术进行了总结和展望。
