Member Function Documentation

addLayer()

bool UwMultiDestination::addLayer ( IP_range  range, int  id  )

virtual

Add a layer in the layer map if the IP range is valide, i.e., if the range doesn't overlap with an existing one.

Parameters

range	IP range
id	identifier of the lower layer return false if the range overlaps with an existing one, true otherwise

Definition at line 144 of file uwmulti-destination.cpp.

checkNotOverlap()

bool UwMultiDestination::checkNotOverlap ( IP_range  range )

protectedvirtual

return true if there is not overlap between the new range and the previous rnage in the list

Parameters

range

that has to be inserted in the list

Returns

true if there is not overlap, false otherwise

Definition at line 201 of file uwmulti-destination.cpp.

command()

int UwMultiDestination::command ( int  argc, const char *const *  argv  )

virtual

TCL command interpreter.

It implements the following OTcl methods:

Parameters

argc	Number of arguments in argv.
argv	Array of strings which are the command parameters (Note that argv[0] is the name of the object).

Returns

TCL_OK or TCL_ERROR whether the command has been dispatched successfully or not.

Definition at line 81 of file uwmulti-destination.cpp.

getDestinationLayer()

int UwMultiDestination::getDestinationLayer ( Packet *  p )

protectedvirtual

Return the best layer to forward the packet when the system works in AUTOMATIC_MODE.

Parameters

p	pointer to the packet

Returns

id of the module representing the best layer.

Definition at line 185 of file uwmulti-destination.cpp.

recv()

void UwMultiDestination::recv ( Packet *  p )

virtual

recv method.

It is called when a packet is received from the other layers

Parameters

Packet*

Pointer to the packet that are going to be received

Definition at line 162 of file uwmulti-destination.cpp.

recvFromUpperLayers()

void UwMultiDestination::recvFromUpperLayers ( Packet *  p )

protectedvirtual

Default lower id to use if dest adress is not found in the considered IP ranges.

Handle a packet coming from upper layers

Parameters

p	pointer to the packet

Definition at line 174 of file uwmulti-destination.cpp.
