本文主要研究了W-WAN中GPRS网络的移动视频传输问题。文中探讨了GPRS的网络结构、协议体系以及链路特性，从中我们看出： GPRS网络链路不仅具有一般无线链路数据传输中遇到的延迟大、误码率高等共性问题，而且具有移动通信系统采用蜂窝频率复用方式带来的小区切换， 以及由于通信中链路性能随着地理位置变换而变化造成的GPRS网络中不可避免的经常性遭遇的冗长时延和突变时延。 这使得目前GPRS网络中使用的传统TCP或UDP传输协议均不能适应GPRS自身的链路特性，也不能实现高效的分组传输。-This paper mainly studied the W-WAN in the GPRS network for mobile video transmission problems. The article discusses the GPRS network architecture, protocol architecture, as well as link characteristics, from which we can see: GPRS network link not only has the general wireless link data transmission delay encountered in large, common problems of higher bit error rate, and with mobile communications system uses a cellular frequency reuse methods brought about by cell switching, as well as the communication link performance with the location change and change is inevitable GPRS network, the recurrent encountered lengthy delay and delay mutation. This makes the current GPRS network using the traditional TCP or UDP transport protocol are una

多协议标签交换 (MPLS) 是 区分和可扩展框架介绍的 IETF，使用简单的配置和管理 提供端到端 IP 服务。它可以使网络 若要指定路径，基于服务质量 (QoS) 的设备 并为这些应用程序所要求的带宽 更改的逐跳范式。容错是 系统的优雅地作出反应的能力 意外的硬件或软件故障。通过使用故障 恢复技术我们可以使 MPLS 网络故障 容错。以模拟在 MPLS 故障恢复技术 网络中，开放源代码模拟器网络模拟器 随着 NS2 的使用，通常被称为 (NS)。我们曾经为 NS2 执行多个容错能力，使用保护 切换在 MPLS 网络中的域。我们开发了一个新的 基于保护切换的故障恢复协议 域，并比较它与 NS2 重新路由故障 恢复协议。我们发现该拟议的故障恢复 议定书 》 更可靠，有较少的恢复时间 单一故障和作为对 NS2 比较多个故障 重新路由故障恢复协议。

This program was designed as a GUI client for the Asterisk PBX with Digium Zaptel cards and SIP VOIP hard or softphones as extensions, it could be adapted to other functions, but It was designed for Zap/SIP users. The program will run on X and Win32. -This program was designed as a GUI client for the Asterisk PBX with Digium Zaptel cards and SIP VOIP hard or softphones as extensions, it could be adapted to other functions, but It was designed for Zap/SIP users.
