[特殊字符] 企业级网络压力测试全流程手册

🔍 1. 测试准备阶段

1.1 环境预检

# env_check.py
import platform, socket, subprocess

def system_info():
    print(f"{'='*40}")
    print(f"🖥️ 系统信息".center(40))
    print(f"操作系统\t{platform.system()} {platform.release()}")
    print(f"主机名\t{socket.gethostname()}")
    print(f"Python\t{platform.python_version()}")
    
def network_info():
    print(f"\n{'='*40}")
    print(f"🌐 网络配置".center(40))
    subprocess.run(["ipconfig", "/all"] if platform.system() == "Windows" else ["ifconfig"])
    
system_info()
network_info

1.2 工具矩阵

🧪 2. 基础测试套件

2.1 增强版Ping测试

# ping_advanced.ps1
$targets = @(
    "gateway",
    "114.114.114.114", 
    "8.8.8.8",
    "www.baidu.com"
)

$results = foreach ($t in $targets) {
    $ping = Test-Connection -TargetName $t -Count 10 -ErrorAction SilentlyContinue
    [PSCustomObject]@{
        Target = $t
        AvgLatency = ($ping.ResponseTime | Measure-Object -Average).Average
        PacketLoss = (10 - $ping.Count)/10*100
    }
}

$results | Format-Table -AutoSize
$results | Export-Csv -Path "ping_results.csv" -NoTypeInformation

2.2 智能端口扫描

# port_scanner.py
import socket
from concurrent.futures import ThreadPoolExecutor

def scan_port(host, port):
    try:
        with socket.socket(socket.AF_INET, socket.SOCK_STREAM) as s:
            s.settimeout(2)
            result = s.connect_ex((host, port))
            return port, result == 0
    except Exception as e:
        return port, f"Error: {str(e)}"

def full_scan(host, ports=range(1, 1025)):
    with ThreadPoolExecutor(max_workers=100) as executor:
        results = executor.map(lambda p: scan_port(host, p), ports)
        for port, status in results:
            if status is True:
                print(f"✅ Port {port}: OPEN")
            elif "Error" not in str(status):
                print(f"❌ Port {port}: CLOSED")

if __name__ == "__main__":
    full_scan("target.example.com")

🚀 3. 进阶测试方案

3.1 全方位带宽压测

# bandwidth_test.sh
#!/bin/bash

SERVER_IP="192.168.1.100"
DURATION=60
THREADS=10

echo "🔄 启动iPerf3服务端..."
iperf3 -s -p 5201 &

echo "⏳ 进行TCP上行测试..."
iperf3 -c $SERVER_IP -t $DURATION -P $THREADS -J > tcp_upload.json

echo "⏳ 进行TCP下行测试..."
iperf3 -c $SERVER_IP -t $DURATION -P $THREADS -R -J > tcp_download.json

echo "⏳ 进行UDP测试..."
iperf3 -c $SERVER_IP -t $DURATION -u -b 1G -J > udp_test.json

echo "📊 生成测试报告..."
python3 generate_report.py tcp_upload.json tcp_download.json udp_test.json

pkill iperf3

3.2 智能流量分析

# 关键过滤条件库

/* 基础过滤 */
icmp || dns || tcp.port == 80 || tcp.port == 443

/* 异常检测 */
tcp.analysis.retransmission || 
tcp.analysis.duplicate_ack || 
tcp.analysis.zero_window

/* 应用层分析 */
http.request.method == "POST" || 
ssl.handshake.type == 1 || 
dns.qry.name contains "api"

🛠️ 4. 深度问题排查

4.1 网络路径诊断

# network_path.ps1
function Trace-NetworkPath {
    param (
        [string]$Target,
        [int]$MaxHops = 30,
        [int]$Timeout = 1000
    )
    
    $results = tracert -d -h $MaxHops -w $Timeout $Target | 
        Where-Object { $_ -match "\d+\s+ms" } |
        ForEach-Object {
            $parts = $_ -split "\s+"
            [PSCustomObject]@{
                Hop = $parts[0]
                IP = $parts[-2]
                Latency = $parts[-3..-1] -join "/"
            }
        }
    
    $results | Export-Csv -Path "tracert_$Target.csv" -NoTypeInformation
    return $results
}

Trace-NetworkPath -Target "www.example.com" -MaxHops 15

4.2 综合连接测试

# connection_test.py
import pycurl
from io import BytesIO

def test_endpoint(url):
    buffer = BytesIO()
    c = pycurl.Curl()
    c.setopt(c.URL, url)
    c.setopt(c.WRITEDATA, buffer)
    c.setopt(c.TIMEOUT, 10)
    
    metrics = {}
    c.setopt(c.WRITEHEADER, lambda h: metrics.update({
        'http_code': c.getinfo(c.HTTP_CODE),
        'connect_time': c.getinfo(c.CONNECT_TIME),
        'total_time': c.getinfo(c.TOTAL_TIME)
    }))
    
    try:
        c.perform()
        return {
            'status': 'success',
            'metrics': metrics,
            'response': buffer.getvalue().decode()
        }
    except Exception as e:
        return {
            'status': 'failed',
            'error': str(e)
        }
    finally:
        c.close()

print(test_endpoint("https://www.baidu.com"))

🤖 5. 自动化运维方案

5.1 智能监控系统

# network_monitor.py
import schedule
import time
import json
from datetime import datetime

class NetworkMonitor:
    def __init__(self):
        self.config = self.load_config()
        
    def load_config(self):
        with open('config.json') as f:
            return json.load(f)
    
    def run_tests(self):
        test_results = {}
        for test in self.config['tests']:
            # 执行各类测试...
            test_results[test['name']] = self.execute_test(test)
        
        self.generate_report(test_results)
    
    def execute_test(self, test_config):
        # 实现具体测试逻辑
        pass
    
    def generate_report(self, results):
        filename = f"report_{datetime.now().strftime('%Y%m%d_%H%M%S')}.html"
        # 生成报告...
        print(f"报告已生成: {filename}")

if __name__ == "__main__":
    monitor = NetworkMonitor()
    schedule.every(15).minutes.do(monitor.run_tests)
    
    while True:
        schedule.run_pending()
        time.sleep(1)

5.2 可视化报告模板

<!-- report_template.html -->
<!DOCTYPE html>
<html>
<head>
    <title>网络测试报告 - {{ date }}</title>
    <style>
        .dashboard {
            display: grid;
            grid-template-columns: repeat(3, 1fr);
            gap: 20px;
        }
        .metric-card {
            border: 1px solid #ddd;
            padding: 15px;
            border-radius: 5px;
        }
        .critical {
            background-color: #ffebee;
        }
    </style>
</head>
<body>
    <h1>网络健康报告</h1>
    <div class="dashboard">
        {% for test in tests %}
        <div class="metric-card {% if test.status == 'critical' %}critical{% endif %}">
            <h3>{{ test.name }}</h3>
            <p>状态: <strong>{{ test.status }}</strong></p>
            <p>延迟: {{ test.latency }} ms</p>
            <p>时间: {{ test.timestamp }}</p>
