Packet switched digital data network 分组交换数字数据网
The Research for Establishing Packet Switched Public Data Network 建立分组交换公用数据网问题的探讨
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。
In traditional way, voice service and data service are provided independently by two different networks-PSTN ( Public Switched Telephone Network) and data communication network. 在传统方式下,话音业务和数据业务是由两个互相独立的网络&公共电话交换网(PSTN)和数据通信网分别提供的。
Facsimile Communication over Packet Switched Data Network 在分组交换数据网上开通传真通信的探讨
To guarantee QoS for periodic real-time data in switched industrial Ethernet, non-preemptive priority scheduling method is introduced into switches, and leaky bucket regulator is used at source nodes to constrain aperiodic data entering into the network. 为保证周期性实时数据在交换式工业以太网中的服务质量,在交换机中引入非抢占式的优先级调度方法,并在源节点对进入网络的非周期数据流进行漏桶管制;
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. 本文叙述了传真通信的现状和存在的问题,着重分析了在分组交换数据网(PSDN)上开通的传真通信,并引出了具有存储、转发传真报文功能的传真通信处理器(FCP);
Value Added Service on the Packet Switched Data Network 分组交换网上的增值业务
The communication of multimedia is mostly based on the Circuit Switching in the past, and with the improvement of the foundation of data operation, the tendency is based on the packet switched data network. 以往的多媒体通信业务主要基于电路交换网络,随着基础数据业务的快速稳定增长和网络规模的持续增长,多媒体通信业务的发展趋势将基于包交换网络,如IP网络。
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。
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。
