- 瞭解 TCP/IP 網路原理
網路數據包分析是一種用於即時查看通過網路介面發送和接收的原始數據的技術。這對於排查網路配置和網路應用程式問題非常有用。Wireshark 是一個免費的開源數據包分析器,用於解決此類網路問題。
在這個由講師指導的現場培訓中,參與者將學習如何使用 Wireshark 對網路功能以及不同網路應用程式的性能進行故障排除。參與者將學習網路故障排除原理和實踐技術,以捕獲和分析不同客戶端和伺服器之間的 TCP/IP 請求和回應流量。
在本次培訓結束時,參與者將能夠:
- 分析不同條件下各種環境中的網路功能和性能
- 確定不同伺服器應用程式的實例的性能是否可接受
- 確定網路性能問題的主要來源
- 確定並解決 TCP/IP 通信中性能問題的最常見原因
