Zusi 3 TCP Protocol Library

An implementation of the Zusi 3 TCP protocol in C++.

This library is currently in an alpha state. It should be possible to send/receive all Zusi messages, but there is only limited error checking and the API will change in the future. The ID enumerations are only partly populated.

Classes

• zusi::Socket - Abstract interface for a network communications class
• zusi::Node - Message node. Has and ID, child attributes and nodes.
• zusi::Attribute - Message attribute. Has an ID, and some data.
• zusi::ClientConnection - Encapsulates a connection to a Zusi 3 server. Negotiates a connection with the server and sends and recieves message for the application.
• zusi::ServerConnection - Emulates a Zusi 3 server. Negotiates a connection with the client and sends data updates.

Samples

• dump_ftd - Connects to server, subscribes to Führerstand variables and displays the contents of received messages
• pfeil_and_go - Connects to server, sounds the horn, and opens the throttle
• server_emulator - Accepts a client connection and sends simulated Speed and Power data to the client

For an example of constructing a message to transmit, see the ClientConnection::connect() method.

Platforms

Currently there is no byte-swapping so it will only work on little-endian architectures.

The library is portable to different platforms by implementing the Socket interface. Two implementations are included - WinsockBlockingSocket, which uses the Windows socket library in blocking mode, and DebugSocket, which prints data to the console insted of sending it.
