Thu Htoo Zan
I work on the network layer: routing, segmentation, and the firewall rules that decide what is allowed to talk to what. Third-year Information Systems and Network Engineering student at Chiang Mai University.

01My degree is taught in English and covers network infrastructure, systems design and information security. I chose it because I wanted to understand how traffic actually moves, not only how to operate the tools that move it.
Reading about a protocol only takes you so far. I learn by setting things up, breaking them, and working out why they broke. I write down what I find as I go.
focus
02Three areas that support each other.
Security
Firewall policy, access control and traffic analysis. Knowing how a network fails is part of knowing how to build one.
Systems & Automation
Linux administration and scripting. A configuration you cannot reproduce is not really a configuration.

03Status is labelled honestly. Everything marked live is online and working right now.
Network Design Console
liveAn offline-first study console for Computer Network Design and Management, built as one HTML file with no dependencies. Covers VLANs, trunking, EtherChannel and inter-VLAN routing, and includes a working 802.1D spanning-tree solver that computes root bridge, port roles and blocked ports from a topology you enter.
Study Console Suite
liveThree more consoles built on the same idea: wireless networks with RF planning and channel reuse, algorithms and data structures with C++ practice, and privacy technologies with entropy-based risk quantification. Each one is a single file that works with no network connection, which is the whole point of them.
