package inet.applications.tcpapp;

//
// Models Telnet sessions with a specific user behaviour.
// The server app should be TCPGenericSrvApp.
// Compatible with both IPv4 and IPv6.
//
// NOTE: This module emulates a very specific user behaviour, and as such,
// it should be viewed as an example rather than a generic Telnet model.
// If you want to model realistic Telnet traffic, you are encouraged
// to gather statistics from packet traces on a real network, and
// write your model accordingly.
//
simple TelnetApp like TCPApp
