Two networking assignments in one place. A packet level analysis in Wireshark, and a routed and switched enterprise network built and tested in Huawei eNSP. Individual work for the Networking course (SOF203).
A byte by byte reading of real captured traffic. It walks through an ARP request and reply, an ICMP echo (ping), and IP fragmentation, mapping each field to its offset in the frame. The capture is included as capture.pcapng, so you can open it and follow along. The full write up is in docs/A1-packet-analysis.pdf.
A small company network designed, addressed, and verified end to end.
- An address plan built with VLSM from a single 10.61.22.0/23 block (512 addresses), split across 5 department LANs and three point to point router links
- 3 routers and 6 PCs, with RIP version 2 for dynamic routing
- A convergence test that cuts a router link and shows the path re-route from 3 hops to 4
- VLANs (200 and 203) across 2 switches with 802.1Q trunking and access ports
The eNSP topology files and device configs live under ensp/, so the whole thing can be reopened in eNSP. The design write up is in docs/A2-network-design.pdf.
