Member Function Documentation

command()

int UwFlooding::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.

Definition at line 110 of file uwflooding.cpp.

getTTL()

uint8_t UwFlooding::getTTL ( Packet *  p ) const

private

Get the value of the TTL.

Parameters

p	pointer to the packet for which the ttl has to be computed.

Returns

the ttl for that packet

Definition at line 378 of file uwflooding.cpp.

printIP()

string UwFlooding::printIP ( const nsaddr_t &  ip_ )

staticprotected

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"

Definition at line 422 of file uwflooding.cpp.

recv()

void UwFlooding::recv ( Packet *  p )

protectedvirtual

Performs the reception of packets from upper and lower layers.

Parameters

Packet*

Pointer to the packet will be received.

Definition at line 155 of file uwflooding.cpp.

recvAsyncClMsg()

int UwFlooding::recvAsyncClMsg ( ClMessage *  m )

protectedvirtual

Cross-Layer messages asynchronous interpreter.

Used to retrive the IP od the current node from the IP module.

Parameters

ClMessage*

an instance of ClMessage that represent the message received and used for the answer.

Returns

0 if successful.

Definition at line 104 of file uwflooding.cpp.

recvSyncClMsg()

int UwFlooding::recvSyncClMsg ( ClMessage *  m )

protectedvirtual

str2addr()

static nsaddr_t UwFlooding::str2addr ( const char *  )

staticprotected

Returns a nsaddr_t address from an IP written as a string in the form "x.x.x.x".

Parameters

char*

IP in string form

Returns

nsaddr_t that contains the IP converter from the input string

writePathInTrace()

void UwFlooding::writePathInTrace ( const Packet *  p, const string &  _info  )

protectedvirtual

Writes in the Path Trace file the path contained in the Packet.

Parameters

Packet
