Detailed Description

A layer between the sockets interface and IP.

This class allocates "endpoint" objects (ns3::Ipv4EndPoint) for TCP, and SHOULD checksum packets its receives from the socket layer going down the stack , but currently checksumming is disabled. It also recieves packets from IP, and forwards them up to the endpoints.

Member Function Documentation

Ptr<Socket> ns3::TcpL4Protocol::CreateSocket

(

void

)

Returns:

A smart Socket pointer to a TcpSocketImpl, allocated by this instance of the TCP protocol

virtual void ns3::TcpL4Protocol::DoDispose

(

void

)

[protected, virtual]

This method is called by Object::Dispose or by the object's destructor, whichever comes first.

Subclasses are expected to implement their real destruction code in an overriden version of this method and chain up to their parent's implementation once they are done. i.e., for simplicity, the destructor of every subclass should be empty and its content should be moved to the associated DoDispose method.

Reimplemented from ns3::Object.

virtual int ns3::TcpL4Protocol::GetProtocolNumber

(

void

)

const [virtual]

Returns:

the protocol number of this protocol.

Implements ns3::Ipv4L4Protocol.

static TypeId ns3::TcpL4Protocol::GetTypeId

(

void

)

[static]

This method returns the TypeId associated to ns3::TcpL4Protocol.

Attributes defined for this type:

• RttEstimatorFactory: How RttEstimator objects are created.
  • Set with class: ObjectFactoryValue
  • Underlying type: ObjectFactory
  • Initial value: ns3::RttMeanDeviation[]

Reimplemented from ns3::Ipv4L4Protocol.

virtual void ns3::TcpL4Protocol::Receive	(	Ptr< Packet >	p,
		Ipv4Address const &	source,
		Ipv4Address const &	destination,
		Ptr< Ipv4Interface >	incomingInterface
	)			[virtual]

Recieve a packet up the protocol stack.

Parameters:

	p	The Packet to dump the contents into
	source	The source's Ipv4Address
	destination	The destinations Ipv4Address
	incomingInterface	The Ipv4Interface it was received on

Implements ns3::Ipv4L4Protocol.

void ns3::TcpL4Protocol::Send	(	Ptr< Packet >	packet,
		Ipv4Address	saddr,
		Ipv4Address	daddr,
		uint16_t	sport,
		uint16_t	dport
	)

Send a packet via TCP.

Parameters:

	packet	The packet to send
	saddr	The source Ipv4Address
	daddr	The destination Ipv4Address
	sport	The source port number
	dport	The destination port number
