Detailed Description

UwUdp class is used to manage UWUDP packets, and flows to and from upper modules.

Constructor & Destructor Documentation

UwUdp()

Destructor of UwUdp class.

Member Function Documentation

assignPort()

int UwUdp::assignPort ( Module *  m )

virtual

Associates a module with a port.

Parameters

Module*

Module to which associate a port.

Returns

Id of the port associated to the module.

References id_map, port_map, and portcounter.

Referenced by command().

command()

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

overridevirtual

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.

Here is the call graph for this function:

getUdpHeaderSize()

static int UwUdp::getUdpHeaderSize ( )

inlinestaticprotected

Returns the size in byte of a hdr_uwudp packet header.

Returns

The size of a hdr_uwudp packet header.

Referenced by command().

printIdsPkts()

void UwUdp::printIdsPkts ( ) const

inline

Prints the IDs of the packet's headers defined by UWUDP.

References PT_UWUDP.

Referenced by command().

recv() [1/2]

void UwUdp::recv ( Packet *  p )

overridevirtual

Performs the reception of packets from upper and lower layers.

Parameters

Packet*

Pointer to the packet will be received.

recv() [2/2]

void UwUdp::recv ( Packet *  p, int  idSrc  )

overridevirtual

Performs the reception of packets from upper and lower layers.

Parameters

Packet*	Pointer to the packet will be received.
Handler*	Handler.

int UwUdp::debug_

protected

Flag to enable or disable debug.

Referenced by UwUdp().

drop_duplicated_packets_

int UwUdp::drop_duplicated_packets_

protected

Flag to enable or disable the drop of duplicated packets.

Referenced by recv(), and UwUdp().

id_map

std::map<int, int> UwUdp::id_map

protected

Map port number to application module id (port_number, id).

Referenced by assignPort(), and recv().

map_packets

portcounter

uint16_t UwUdp::portcounter

protected

Counter used to generate new port numbers.
