Course Code: wireshark
Duration: 21 hours
Prerequisites:
  • 了解 TCP/IP 网路原理
Overview:

网路数据包分析是一种用于即时查看通过网路介面发送和接收的原始数据的技术。这对于排查网路配置和网路应用程式问题非常有用。Wireshark 是一个免费的开源数据包分析器,用于解决此类网路问题。

在这个由讲师指导的现场培训中,参与者将学习如何使用 Wireshark 对网路功能以及不同网路应用程式的性能进行故障排除。参与者将学习网路故障排除原理和实践技术,以捕获和分析不同客户端和伺服器之间的 TCP/IP 请求和回应流量。

在本次培训结束时,参与者将能够:

  • 分析不同条件下各种环境中的网路功能和性能
  • 确定不同伺服器应用程式的实例的性能是否可接受
  • 确定网路性能问题的主要来源
  • 确定并解决 TCP/IP 通信中性能问题的最常见原因
