class | Tcp |
An implementation of a stream socket using TCP.
This class contains an implementation of TCP Tahoe, as well as a sockets interface for talking to TCP. Features include connection orientation, reliability through cumulative acknowledgements, congestion and flow control. Finite send buffer semantics are modeled, but as of yet, finite receive buffer modelling is unimplemented.
The closedown of these sockets is as of yet not compliant with the relevent RFCs, i.e. the FIN handshaking isn't correct. While this is visible at the PCAP tracing level, it has no effect on the statistics users are interested in, i.e. throughput, delay, etc. of actual payload data.
Asynchronous callbacks to provide notifications to higher layers that a protocol event has occured, such as space freeing up in the send buffer or new data arriving in the receive buffer.

Read data from the socket.
This function matches closely in semantics to the recv() function call in the standard C library (libc): ssize_t recv (int s, void *buf, size_t len, int flags); except that the receive I/O is asynchronous. This is the primary Recv method at this low-level API and must be implemented by subclasses.
This method is normally used only on a connected socket. In a typical blocking sockets model, this call would block until at least one byte is returned or the connection closes. In ns-3 at this API, the call returns immediately in such a case and returns 0 if nothing is available to be read. However, an application can set a callback, ns3::SetRecvCallback, to be notified of data being available to be read (when it conceptually unblocks); this is an asynchronous I/O model for recv().
This variant of Recv() uses class ns3::Packet to encapsulate data, rather than providing a raw pointer and length field. This allows an ns-3 application to attach tags if desired (such as a flow ID) and may allow the simulator to avoid some data copies. Despite the appearance of receiving Packets on a stream socket, just think of it as a fancy byte buffer with streaming semantics.
The semantics depend on the type of socket. For a datagram socket, each Recv() returns the data from at most one Send(), and order is not necessarily preserved. For a stream socket, the bytes are delivered in order, and on-the-wire packet boundaries are not preserved.
The flags argument is formed by or'ing one or more of the values: MSG_OOB process out-of-band data MSG_PEEK peek at incoming message None of these flags are supported for now.
Some variants of Recv() are supported as additional API, including RecvFrom(), overloaded Recv() without arguments, and variants that use raw character buffers.

Read a single packet from the socket and retrieve the sender address.
Calls Recv(maxSize, flags) with maxSize implicitly set to maximum sized integer, and flags set to zero.
This method has similar semantics to Recv () but subclasses may want to provide checks on socket state, so the implementation is pushed to subclasses.

fromAddress | output parameter that will return the address of the sender of the received packet, if any. Remains untouched if no packet is received. |

Send data (or dummy data) to the remote host.
This function matches closely in semantics to the send() function call in the standard C library (libc): ssize_t send (int s, const void *msg, size_t len, int flags); except that the send I/O is asynchronous. This is the primary Send method at this low-level API and must be implemented by subclasses.
In a typical blocking sockets model, this call would block upon lack of space to hold the message to be sent. In ns-3 at this API, the call returns immediately in such a case, but the callback registered with SetSendCallback() is invoked when the socket has space (when it conceptually unblocks); this is an asynchronous I/O model for send().
This variant of Send() uses class ns3::Packet to encapsulate data, rather than providing a raw pointer and length field. This allows an ns-3 application to attach tags if desired (such as a flow ID) and may allow the simulator to avoid some data copies. Despite the appearance of sending Packets on a stream socket, just think of it as a fancy byte buffer with streaming semantics.
If either the message buffer within the Packet is too long to pass atomically through the underlying protocol (for datagram sockets), or the message buffer cannot entirely fit in the transmit buffer (for stream sockets), -1 is returned and SocketErrno is set to ERROR_MSGSIZE. If the packet does not fit, the caller can split the Packet (based on information obtained from GetTxAvailable) and reattempt to send the data.
The flags argument is formed by or'ing one or more of the values: MSG_OOB process out-of-band data MSG_DONTROUTE bypass routing, use direct interface These flags are _unsupported_ as of ns-3.1.
