C#下实现模拟red阻塞控制实验

最近计算机网络学习网络层的tcp协议相关程序，要模拟测试RED算法中的Thmin与Thmax故写如下算法，并开启我的博客第一篇，首先，我建立了一个数据源类用来模拟慢开始快重传，快恢复算法

using System;using System.Collections.Generic;using System.Linq;using System.Text;namespace RED{class ComputerDataSourse{private int currentvalue = 0;    //每次发送的包的个数public void send(){currentvalue++;Form1.currentQ += currentvalue;}public void reset(){currentvalue = 0;Form1.breaknum++;}}}

然后是控制类的实现

using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Linq;using System.Text;using System.Windows.Forms;using System.IO;using System.Runtime.InteropServices;using Excel = Microsoft.Office.Interop.Excel;namespace RED{public partial class Form1 : Form{public  static   int M = 0;Random random = new Random();public  static  int Q = 0;public  static  decimal pmax;private int thmin = 0;private int thmax = 0;private int lastQ = 0;public static int Finshed = 0; //已经发送的包的个数；public static  int breaknum = 0;//丢弃掉的包的个数public  static int currentQ = 0;//当前队列的长度private int count = 0;//新到达的分组进入队列的个数private int des = 30;//每单位时间从路由队列中出去的包个数private int time = 0;private ComputerDataSourse d1, d2, d3, d4, d5;public Form1(){InitializeComponent();d1 = new ComputerDataSourse();d2 = new ComputerDataSourse();d3 = new ComputerDataSourse();d4 = new ComputerDataSourse();d5 = new ComputerDataSourse();timer1.Enabled = false;timer1.Interval = 50;}private decimal getP(){decimal  ptem = pmax*(currentQ-thmin)/(thmax-thmin);return (ptem/(1-count*ptem));}private void run(){if (Finshed < M){if (currentQ < thmin){d1.send();d2.send();d3.send();d4.send();d5.send();}else if (currentQ > thmax){d1.reset();d2.reset();d3.reset();d4.reset();d5.reset();}else{decimal p = getP();count += (int)(5 - (currentQ-lastQ) * p);for (int i = 0; i < 40 * p; i++){int r = random.Next(5);switch (r){case 0: d1.reset(); break;case 1: d2.reset(); break;case 2: d3.reset(); break;case 3: d4.reset(); break;case 4: d5.reset(); break;}}}lastQ = currentQ;if (currentQ > 30){Finshed += 30;currentQ -= 30;}else{Finshed += currentQ;currentQ = 0;}}else{timer1.Enabled = false;}}private void button1_Click(object sender, EventArgs e){Excel.Application m_excel = new Excel.Application();m_excel.SheetsInNewWorkbook = 1;Excel._Workbook m_book = (Excel._Workbook)(m_excel.Workbooks.Add(true));Excel._Worksheet m_sheet;}private void button_run_Click(object sender, EventArgs e){try{Finshed = 0; ;breaknum = 0;currentQ = 0;count = 0;time = 0;textBox_count.Text = "";M = Convert.ToInt16(textBox_m.Text.Trim());textBox_m.ReadOnly = true;Q = Convert.ToInt16(textBox_q.Text.Trim());textBox_q.ReadOnly = true;pmax = Convert.ToDecimal(textBox_p.Text.Trim());textBox_p.ReadOnly = true;thmin = Convert.ToInt16(textBox_min.Text.Trim());thmax = Convert.ToInt16(textBox_max.Text.Trim());}catch(Exception ee){MessageBox.Show(ee.Message);}timer1.Enabled = true;}private void timer1_Tick(object sender, EventArgs e){run();textBox_count.Text = breaknum.ToString();time++;textBox_time.Text = time.ToString();}private void Form1_Load(object sender, EventArgs e){}}}
