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   ) 

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]

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:

Attributes defined in parent class ns3::Ipv4L4Protocol:
  • ProtocolNumber: The Ipv4 protocol number.
No TraceSources defined for this type.

Reimplemented from ns3::Ipv4L4Protocol.

virtual void ns3::TcpL4Protocol::NotifyNewAggregate (  )  [protected, virtual]

This function is called by the AggregateObject on all the objects connected in the listed chain. This way the new object aggregated will be used if needed by the NotifyNewAggregate corresponding to each object connected in the listed chain. It should be implemented by objects needing an additional/special behavior when aggregated to another object.

Reimplemented from ns3::Object.

virtual enum Ipv4L4Protocol::RxStatus ns3::TcpL4Protocol::Receive ( Ptr< Packet p,
Ipv4Address const &  source,
Ipv4Address const &  destination,
Ptr< Ipv4Interface incomingInterface 
) [virtual]

Recieve a packet up the protocol stack.

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.

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