Detailed Description

Basic IP routing functionality.

This class implements tcl class Module/IP/Routing and is expected to be installed above one or more Module/IP/Interface classes.

Note:

Inheritance from IPModule is actually needed only for the str2add() method et similia. Other functionality from the IPModule is not needed in IPRoutingModule, and all methods are overloaded. In particular, it should be remembered that an IPRoutingModule does *NOT* have its own IP address.

Member Function Documentation

void IPRoutingModule::recv

(

Packet *

p

)

[virtual]

Abstract method which has to be filled with the ad-hoc operations that the module has to do to the packet received

Parameters:

p

pointer to the packet will be received

Here is the call graph for this function:

int IPRoutingModule::command	(	int	argc,
		const char *const *	argv
	)			[virtual]

TCL command interpreter. It implements the following OTcl methods:

• addupsap <SAP instance>: add a new SAP instance to the upLayerSAP_ pointers array
• adddownsap <SAP instance>: add a new SAP instance to the downLayerSAP_ pointers array

Moreover it inherits all the OTcl method of PlugIn

Parameters:

	argc	number of arguments in argv
	argv	array of strings which are the comand parameters (Note that argv[0] is the name of the object)

Returns:

TCL_OK or TCL_ERROR whether the command has been dispatched succesfully or no
