描述

Visual TCPIP Trainer
全新  Visual TCP/IP Trainer is an educational simulator that lets you see how network communication works. With a simple 4-node topology (PC1 → RT1 → RT2 → PC2) across three segments (172.160.0.0/28, 10.0.0.4/30, 192.168.100.0/28), you can visualize packet flows in real time. Track MAC, IP, TTL, and ICMP at each hop, while the ARP table updates dynamically.

Key Features

Network Topology View: 4 nodes and 3 segments at a glance

Simulation Control: Forward/Reverse, Start/Pause/Reset, Step execution

Detailed View: Frame details (MAC, IP, TTL, ICMP), hop table, real-time ARP table

Challenges (30 total): Beginner/Intermediate/Advanced. Each with Q → Answer → Key point/Field insight. Advanced includes real device command examples

Multilingual: Switch between Japanese and English (challenges included)

What You’ll Learn

TTL behavior: unchanged in L2, decreases only when passing through routers

ARP basics: Who has / is-at, Unknown Unicast handling, effects of Proxy ARP

ICMP and PMTUD: black-hole troubleshooting, MTU-related issues

Why ping fails but TCP works: ICMP control, MTU/PMTUD perspective

Challenge Examples

Same L2, PC-A → PC-B ping: what happens to TTL?

Why does ping fail but TCP works?

What is Proxy ARP? When should it be enabled or disabled?

Longest prefix match in routing (/8, /16, /24 coexistence)

Target Users

Junior engineers / networking beginners

Certification learners (CCNA / CCNP / CCIE)

Trainers or engineers who need demo/teaching tools

Use Cases

Step through from ARP resolution to ICMP reply

Observe MAC/IP/TTL changes via hop table

Reinforce understanding with challenge Q&A and field insights
