In Packet Path, networking concepts come to life through interactive tasks rather than static diagrams. You construct the network, hit «Send packet», and observe its journey across nodes.
The log details each step: why a PC broadcasts an address request, how switches keep track of ports, the decreasing TTL of packets, and what happens to frames without a predefined route. Errors are clear: packets don't disappear without explanation; they halt due to specific issues.
With 17 levels spanning three chapters — covering cables and addresses, routing, and DNS — the game offers a variety of equipment: PCs, servers, switches, hubs, bridges, routers, and DNS servers. There's also a sandbox mode for experimentation: build, break, and analyze your network setups. Your networks are saved for future exploration.
Available in Russian and English, controlled with mouse and keyboard.
How to play
The task is displayed at the top of the screen — typically, you need to ensure that a packet reaches a specific node.
The game is controlled with the mouse. When you click on a node, its settings appear on the right: address with a mask, default gateway, routing table, DNS server address — the specifics depend on the device. You can enter the values and apply them by pressing Enter or moving out of the field. You can move a node around the map by dragging it.
Use the «Link» button to connect two nodes with a cable: click the button, then select one node and then the other. «Remove» lets you delete a node or a cable, while the «Add» row allows you to add new devices.
To begin the walkthrough, click «Send packet»: the packet will traverse the map, and the log on the right will explain each step. The speed can be adjusted, and clicking on any log entry provides more details.
If you get stuck, there's a «Hint» next to the goal. «Reset map» will return the level to its initial state.
