Taifeng's Wireshark Lab

Making Wireshark protocol analysis easier — replacing guesswork with certainty.

Hi, I’m Taifeng Tan.

I’m a former Cisco networking technology instructor, holding three CCIE certifications, along with CISM, CGEIT, and PMP.

Over the years, I’ve worked at companies like Microsoft, Huawei, and Amazon, across roles in network engineering, security, cloud services, and compliance.
During that time, I’ve handled countless real production incidents and complex troubleshooting cases.

Through those experiences, I gradually developed a set of practical, repeatable, and verifiable methods for protocol analysis and network troubleshooting.

On this channel, I share those methods.

My goal is simple:

👉 Make TCP/IP protocol learning easier
👉 Help engineers use the right analysis frameworks to understand packets
👉 Turn complex network problems into clear, solvable systems

If you want to truly understand Wireshark, TCP congestion control, and network performance, you’re in the right place.
