Description: 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 unable to adapt its own GPRS link characteristics, but also efficient packet transmission can not be achieved.

Description: TCP性能分析。两个分析模型：拥塞控制，各种场景；给出仿真练习；-two analytical models for TCP’s throughput are compared with simulated
results. Based on the study, an ns2 simulation exercise is developed for the course “Simulation of
telecommunications networks”. The goal of the exercise is to make the students familiar with ns2
simulator as well as TCP’s congestion control and performance. Furthermore, the purpose is to give
an idea of how analytical models can be verified with simulations.
The structure of the study is following: In the first part, instructions for the simulation exercise are
given. The instructions consist of theory explaining TCP’s congestion control algorithms and the
analytical models for TCP’s throughput and description of the main features of ns2 simulator and
Otcl language. Finally, in the second part of the study, simulation results from different scenarios
are presented and analysed.

Description: Transmission Control Protocol (TCP) is the dominant transport protocol in the Internet and
supports many of the most popular Internet applications, such as the World Wide Web (WWW),
file transfer and e-mail. TCP congestion control algorithms dynamically learn the network
bandwidth and delay characteristics of a network and adapt its performance to changes in traffic
so as to avoid network collapse.
