如何做網際網路的效能測試
如何做跨區線路測試，分析兩區域網路傳輸的狀況。例如 ap-southeast-1 到 us-east-1 的網路效率。
解題方向
在進行跨區的網路線路測試時，不考慮服務運行時間的情況下，可能會關注以下指標：
- 延遲（Latency）：延遲是從發送請求到收到響應所需的時間。你會測試不同地區之間的平均延遲、最大延遲和最小延遲，以評估網路的反應速度。可使用工具
ping、traceroute、mtr來做測試。 - 丟包率（Packet Loss Rate）：丟包率是指在網絡傳輸過程中丟失的數據包的比率。你會關注丟包率的高低，因為高丟包率可能導致數據傳輸的不完整和延遲增加。可使用工具
ping、traceroute、mtr來做測試。 - 頻寬利用率（Bandwidth Utilization）：帶寬利用率是指在一定時間內使用的網絡帶寬的比率。你會測試網絡的帶寬利用率，以確保帶寬資源充足並且沒有過度使用。可用工具
iperf、speedtest-cli做測試。 - 往返時間（Round-Trip Time，RTT）：RTT 是從發送一個數據包到收到對應的響應所需的時間。你會關注不同地區之間的平均 RTT，以評估網路的往返時間。可使用工具
ping、traceroute、mtr、iperf來做測試。 - 連通性和穩定性（Connectivity and Stability）：你會測試不同地區之間的連通性和穩定性，確保網路連接的可靠性和持久性。可使用工具
ping、traceroute、mtr來做測試。 - DNS 解析時間（DNS Resolution Time）：DNS 解析時間是指從域名解析請求開始到獲得對應 IP 地址的時間。你會測試 DNS 解析時間，以評估域名解析的效率和穩定性。可使用工具
dig、nslookup來做測試。
