摘要
Abstract
The bandwidth resource of satellite link is scarce. How to make maximum use of bandwidth resource is an impor-tant content of satellite network technology in the current study. The researchers have done a lot of research work on en-hancing TCP performance, however, little research has been done on the subject of how to do TCP simulation and how to build simulation platform. The purpose of this paper is to provide a general and flexible method on simulation of TCP con-nection of satellite link, NS-3 is a new freely simulate software of discrete events for the networks research. This paper simulates TCP connection on satellite link via building simulation scene of satellite link on NS-3, and analyzes 11 kinds of TCP congestion control algorithm in Linux kernel via combining NS-3 with Linux kernel. This paper provides a method of TCP simulation based on NS-3. Readers can simulate TCP connection of satellite link according to this method, of course, can also simulate TCP connection of other scenes. Finally, the simulation results indicate that the proposed methods are correct and resultful.关键词
