ITCPApp

module interface

Template for TCP applications. It shows what gates a TCP app needs, to be able to be used in StandardHost etc.

Inheritance diagram

The following diagram shows inheritance relationships for this type. Unresolved types are missing from the diagram.

Implemented by

Name	Type	Description
BGPRouting	simple module	Implements BGP Version 4. TODO config file!
HttpBrowser	simple module	The component is derived from HttpBrowseBase and is intended to be used with the INET frameworks StandardHost and TCP/IP stack modeling.
HttpServer	simple module	A Web server module for OMNeT++ simulations. This module is intended for use with the INET StandardHost module and plugs in as a tcpApp. The INET TCP/IP stack modeling is used for transport. See the INET documentation for more details.
HttpServerEvilA	simple module	Demonstrates subclassing the server to create a custom site. This site is an attacker -- a puppetmaster -- which serves HTML pages containing attack code. In this case, we are simulating JavaScript attack code which prompts the unsuspecting browser to request a number of images from a victim site. Delays are specified to simulate hiding the attack from the browser user by use of JavaScript timeouts or similar mechanisms. The generateBody virtual function is redefined to create a page containing the attack code.
HttpServerEvilB	simple module	HttpServerEvilB
TCPBasicClientApp	simple module	Client for a generic request-response style protocol over TCP. May be used as a rough model of HTTP or FTP users. Compatible with both IPv4 (IPv4) and IPv6.
TCPEchoApp	simple module	Accepts any number of incoming TCP connections, and sends back the messages that arrive on them, The lengths of the messages are multiplied by echoFactor before sending them back (echoFactor=1 will result in sending back the same message unmodified.) The reply can also be delayed by a constant time (echoDelay parameter).
TCPGenericSrvApp	simple module	Generic server application for modelling TCP-based request-reply style protocols or applications.
TCPSessionApp	simple module	Single-connection TCP application: it opens a connection, sends the given number of bytes, and closes. Sending may be one-off, or may be controlled by a "script" which is a series of (time, number of bytes) pairs. May act either as client or as server, and works with TCPVirtualBytesSendQueue/RcvQueue as sendQueue/receiveQueue setting for TCP. Compatible with both IPv4 (IPv4) and IPv6.
TCPSinkApp	simple module	Accepts any number of incoming TCP connections, and discards whatever arrives on them. Compatible with both IPv4 and IPv6.
TCPSrvHostApp	simple module	This module hosts TCP-based server applications. It dynamically creates and launches a new "thread" object for each incoming connection.
TelnetApp	simple module	Models Telnet sessions with a specific user behaviour. The server app should be TCPGenericSrvApp. Compatible with both IPv4 and IPv6.

Used in compound modules

Name	Type	Description
StandardHost	compound module	IPv4 host with SCTP, TCP, UDP layers and applications. IP forwarding is disabled by default (see forwarding).

Known subclasses

Name	Type	Description
IBGPRouting	module interface	Interface for BGP routing module.
