With broadband multimedia services and growing demand for data services the traditional switched network can not function to quickly create and deploy ; not carry voice / data / video / integrated multimedia services ; business network with closed vertical architecture .
随着人们对宽带多媒体业务和数据业务的需求持续增长，传统的 交换网络不能快速创建并部署功能；不能承载话音/ 数据/视频/综合多媒体业务；业务 网络采用封闭、垂直体系结构。
Code for acceptance of public packet switched data network engineering
公用分组 交换 数据 网工程验收规范
This paper describes the existing status and problems of our facsimile communications and puts special stress on analysing facsimile communications over Packet Switched Data Network ( PSDN ) . A Facsimile Communication Processor ( FCP ) which has a message storage and delivery function is introduced .

Puts forward that in the project implementation stage the division of work boundary of transmission network and the fiber optic cable line switched network data network power and other communication system . 5 .
提出了工程实施阶段传输网与光缆线路、 交换网、 数据 网、电源等其它通信系统的分工界面。
Packet switched digital data network
分组 交换数字 数据 网
It is important to schedule data traffic reasonably if QoS is required in a packet switched data network such as TCP / IP network .
对数据流量进行合理调度在诸如TCP/IP这样的分组 交换 网络提供QoS服务过程中是很重要的。
Value Added Service on the Packet Switched Data Network
分组 交换 网上的增值业务
Internet is a packet switched network which provided Best-effort service at the beginning . It supports the FTP protocol E-mail HTTP etc. These traditional data services do not ask for higher performance of the network delay .
互联网发展的初期，是提供尽力而为服务的分组 交换网网络，它主要支持FTP协议、E-mail、HTTP等相对传统的 数据业务，这些业务对 网络时延等性能要求不高。
