Member Function Documentation

command()

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

protectedvirtual

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:

getAckPktHeaderSize()

static const int UwIcrpSink::getAckPktHeaderSize ( )

inlinestaticprotected

Returns the size in byte of a hdr_uwicrp_ack packet header.

Returns

The size of a hdr_uwicrp_ack packet header.

Referenced by command().

getDataPktHeaderSize()

static const int UwIcrpSink::getDataPktHeaderSize ( )

inlinestaticprotected

Returns the size in byte of a hdr_uwicrp_data packet header.

Returns

The size of a hdr_uwicrp_data packet header.

Referenced by command().

getStatusPktHeaderSize()

static const int UwIcrpSink::getStatusPktHeaderSize ( )

inlinestaticprotected

Returns the size in byte of a hdr_uwicrp_status packet header.

Returns

The size of a hdr_uwicrp_status packet header.

initialize()

void UwIcrpSink::initialize ( )

protectedvirtual

Initializes a UwIcrpSink node. It sends to the lower layers a Sync message asking for the IP of the node.

initStatusPkt()

void UwIcrpSink::initStatusPkt ( Packet *  p_old, Packet *  p_new  )

protectedvirtual

Initializes a Status Packet previously allocated.

Parameters

Packet*	Pointer to a PT_UWICRP_STATUS Packet to use to retrieve the information to initialize the new packet.
Packet*	Pointer to a PT_UWICRP_STATUS Packet to initialize.

Here is the call graph for this function:

printIP()

string UwIcrpSink::printIP ( const uint8_t  _ip )

protectedvirtual

Return a string with an IP in the classic form "x.x.x.x" converting an ns2 nsaddr_t address.

Parameters

nsaddr_t&

ns2 address

Returns

String that contains a printable IP in the classic form "x.x.x.x"

recv()

void UwIcrpSink::recv ( Packet *  p )

protectedvirtual

Performs the reception of packets from upper and lower layers.

Parameters

Packet*

Pointer to the packet will be received.

Here is the call graph for this function:

recvAsyncClMsg()

int UwIcrpSink::recvAsyncClMsg ( ClMessage *  m )

protectedvirtual

Initializes a UwIcrpSink node. It sends to the lower layers a Sync message asking for the IP of the node.

References UWIPClMsgSendAddr::getAddr(), ipAddr_, and UWIP_CLMSG_SEND_ADDR.

Here is the call graph for this function:

recvSyncClMsg()

int UwIcrpSink::recvSyncClMsg ( ClMessage *  m )

protectedvirtual

Cross-Layer messages synchronous interpreter.

Parameters

ClMessage*

an instance of ClMessage that represent the message received

Returns

0 if successful.

sendBackAck()

void UwIcrpSink::sendBackAck ( const Packet *  p )

protectedvirtual

Creates an ack packet and sends it to the previous hop using the information contained in the header of the data packet passed as input parameter. It is an ack to the previous hop, and not to the source of the packet.

Parameters

Packet*

Pointer to a Data packet to acknowledge.
