Studying TCP's Throughput and Goodput using NS What is Throughput Throughput is the amount of data received by the destination. The Average Throughput is the throughput per unit of time Example: Suppose a TCP receiver receives 60 M Bytes of data in 1…

Studying TCP's Congestion Window using NS How to obtain TCP's CWND value The most important value that determine the behavior of TCP is the congestion window size or traditionally abreviated as CWND In NS, every TCP-type class (Agent/TCP/Tahoe, (Agen…

实验目的 学习TCP的拥塞控制机制,并了解TCP Tahoe 和 TCP Reno的运行方式. 基础知识回顾 TCP/IP (Transmission Control Protocol/Internet Protocol)是目前使用最广泛的一组通信协议.TCP所负责的功能包括:将自应用程序收到的信息分成许多较小的数据区段.提供连接导向的服务.提供可靠性服务.提供应用程序与应用和式之间的流量控制,并依据网络的状况提供拥塞控制. 当应用程序有数据要传送到网上去时,为了希望能和网络上其他的TCP联机公…
