Member Typedef Documentation

◆ map_forwarded_packets

typedef std::map<uint8_t, map_packets> UwFlooding::map_forwarded_packets

private

Typedef for a map of the packet forwarded (saddr, map_packets).

◆ map_packets

typedef std::map<uint16_t, double> UwFlooding::map_packets

private

Typedef for a packet id: (serial_number, timestamp).

Constructor & Destructor Documentation

◆ UwFlooding() [1/2]

UwFlooding::UwFlooding ( )

Constructor of UwFlooding class.

References maximum_cache_time_, optimize_, and ttl_.

◆ ~UwFlooding()

UwFlooding::~UwFlooding ( )

virtual

Destructor of UwFlooding class.

◆ UwFlooding() [2/2]

UwFlooding::UwFlooding ( const UwFlooding & )

private

Copy constructor declared as private. It is not possible to create a new UwFlooding object passing to its constructor another UwFlooding object.

Parameters

UwFlooding& UwFlooding object.

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.

References ipAddr_, packets_forwarded_, trace_file_path_, trace_file_path_name_, trace_path_, and ttl_traffic_map.

◆ 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

Referenced by recv().

Here is the call graph for this function:

◆ 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"

◆ 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.

Here is the call graph for this function:

◆ 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.

◆ recvSyncClMsg()

int UwFlooding::recvSyncClMsg ( ClMessage * m )

protectedvirtual

Cross-Layer messages synchronous interpreter.

Parameters

ClMessage* an instance of ClMessage that represent the message received

Returns: 0 if successful.

◆ 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 to analyze.
