A low-level Socket API based loosely on the BSD Socket API.
Introspection did not find any typical Config paths.
A few things to keep in mind about this type of socket:
Other than that, it tries to stick to the BSD API to make it easier for those who know the BSD API to use this API. More details are provided in the ns-3 tutorial.
No Attributes are defined for this type.
No TraceSources are defined for this type.
Group: Network
Size of this type is 176 bytes (on a 64-bit architecture).
Enumeration of the possible filter of a socket.
A socket can have filters on specific sources to include only packets incoming from them, or to exclude packets incoming from specific sources. Moreover, inclusion and exclusion also works as a leave, since "joining" a group without allowed sources is equivalent to leaving it.

Bind a socket to specific device.
This method corresponds to using setsockopt() SO_BINDTODEVICE of real network or BSD sockets. If set on a socket, this option will force packets to leave the bound device regardless of the device that IP routing would naturally choose. In the receive direction, only packets received from the bound interface will be delivered.
This option has no particular relationship to binding sockets to an address via Socket::Bind (). It is possible to bind sockets to a specific IP address on the bound interface by calling both Socket::Bind (address) and Socket::BindToNetDevice (device), but it is also possible to bind to mismatching device and address, even if the socket can not receive any packets as a result.

Destructor implementation.
This method is called by Dispose() or by the Object's destructor, whichever comes first.
Subclasses are expected to implement their real destruction code in an overridden 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.
It is safe to call GetObject() from within this method.

Return the priority corresponding to a given TOS value.
This function is implemented after the Linux rt_tos2priority function. The usage of the TOS byte has been originally defined by RFC 1349 (http://www.ietf.org/rfc/rfc1349.txt):
0 1 2 3 4 5 6 7 +-----+-----+-----+-----+-----+-----+-----+-----+ | PRECEDENCE | TOS | MBZ | +-----+-----+-----+-----+-----+-----+-----+-----+
where MBZ stands for 'must be zero'.
The Linux rt_tos2priority function ignores the precedence bits and maps each of the 16 values coded in bits 3-6 as follows:
Bits 3-6 | Means | Linux Priority |
---|---|---|
0 | Normal Service | Best Effort (0) |
1 | Minimize Monetary Cost | Best Effort (0) |
2 | Maximize Reliability | Best Effort (0) |
3 | mmc+mr | Best Effort (0) |
4 | Maximize Throughput | Bulk (2) |
5 | mmc+mt | Bulk (2) |
6 | mr+mt | Bulk (2) |
7 | mmc+mr+mt | Bulk (2) |
8 | Minimize Delay | Interactive (6) |
9 | mmc+md | Interactive (6) |
10 | mr+md | Interactive (6) |
11 | mmc+mr+md | Interactive (6) |
12 | mt+md | Int. Bulk (4) |
13 | mmc+mt+md | Int. Bulk (4) |
14 | mr+mt+md | Int. Bulk (4) |
15 | mmc+mr+mt+md | Int. Bulk (4) |
RFC 2474 (http://www.ietf.org/rfc/rfc2474.txt) redefines the TOS byte:
0 1 2 3 4 5 6 7 +-----+-----+-----+-----+-----+-----+-----+-----+ | DSCP | CU | +-----+-----+-----+-----+-----+-----+-----+-----+
where DSCP is the Differentiated Services Code Point and CU stands for 'currently unused' (actually, RFC 3168 proposes to use these two bits for ECN purposes). The table above allows to determine how the Linux rt_tos2priority function maps each DSCP value to a priority value. Such a mapping is shown below.
DSCP | Hex | TOS (binary) | bits 3-6 | Linux Priority |

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.

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 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.

Configure whether broadcast datagram transmissions are allowed.
This method corresponds to using setsockopt() SO_BROADCAST of real network or BSD sockets. If set on a socket, this option will enable or disable packets to be transmitted to broadcast destination addresses.

void ns3::Socket::SetCloseCallbacks | ( | Callback< void, Ptr< Socket > > | normalClose, |
Callback< void, Ptr< Socket > > | errorClose ) |
Detect socket recv() events such as graceful shutdown or error.
For connection-oriented sockets, the first callback is used to signal that the remote side has gracefully shut down the connection, and the second callback denotes an error corresponding to cases in which a traditional recv() socket call might return -1 (error), such as a connection reset. For datagram sockets, these callbacks may never be invoked.
normalClose | this callback is invoked when the peer closes the connection gracefully |
errorClose | this callback is invoked when the connection closes abnormally |

On Linux, the socket priority can be set to a value in the range [0..6], unless the user process has the CAP_NET_ADMIN capability (see the man page for socket). ns-3 allows users to set the socket priority to any 8-bit non-negative value, which is equivalent to assuming that the CAP_NET_ADMIN capability is set.
