Detailed Description

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:

  • it uses ns-3 API constructs such as class ns3::Address instead of C-style structs
  • in contrast to the original BSD socket API, this API is asynchronous: it does not contain blocking calls. Sending and receiving operations must make use of the callbacks provided.
  • It also uses class ns3::Packet as a fancy byte buffer, allowing data to be passed across the API using an ns-3 Packet instead of a raw data pointer.
  • Not all of the full POSIX sockets API is supported

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.
Size of this type is 152 bytes (on a 64-bit architecture).

Member Enumeration Documentation

◆ Ipv6MulticastFilterMode

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() [2/2]

virtual int ns3::Socket::Bind ( )
pure virtual

Allocate a local IPv4 endpoint for this socket.

Returns
0 on success, -1 on failure.

Implemented in ns3::TcpSocketBase, ns3::PacketSocket, ns3::UdpSocketImpl, ns3::Ipv6RawSocketImpl, ns3::NscTcpSocketImpl, and ns3::Ipv4RawSocketImpl.

◆ Bind6()

virtual int ns3::Socket::Bind6 ( )
pure virtual

◆ BindToNetDevice()

void ns3::Socket::BindToNetDevice ( Ptr< NetDevice netdevice)
virtual

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.

Parameters
netdevicePointer to NetDevice of desired interface
Returns
nothing

◆ DoDispose()

void ns3::Socket::DoDispose ( void  )
protectedvirtual

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.

Reimplemented from ns3::Object.

◆ IpTos2Priority()

uint8_t ns3::Socket::IpTos2Priority ( uint8_t  ipTos)
static

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.

◆ Recv() [1/3]

virtual Ptr<Packet> ns3::Socket::Recv ( uint32_t  maxSize,
uint32_t  flags 
)
pure virtual

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.

Parameters
maxSizereader will accept packet up to maxSize
flagsSocket control flags
Returns
Ptr<Packet> of the next in-sequence packet. Returns 0 if the socket cannot return a next in-sequence packet conforming to the maxSize and flags.

◆ Send() [1/3]

virtual int ns3::Socket::Send ( Ptr< Packet p,
uint32_t  flags 
)
pure virtual

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.

Parameters
pns3::Packet to send
flagsSocket control flags
Returns
the number of bytes accepted for transmission if no error occurs, and -1 otherwise.

◆ SetPriority()

void ns3::Socket::SetPriority ( uint8_t  priority)

Manually set the socket priority.

This method corresponds to using setsockopt () SO_PRIORITY of real network or BSD sockets. 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.

Parameters
priorityThe socket priority

◆ SetSendCallback()

void ns3::Socket::SetSendCallback ( Callback< void, Ptr< Socket >, uint32_t >  sendCb)

Notify application when space in transmit buffer is added.

This callback is intended to notify a socket that would have been blocked in a blocking socket model that space is available in the transmit buffer and that it can call Send() again.

Parameters
sendCbCallback for the event that the socket transmit buffer fill level has decreased. This callback is passed a pointer to the socket, and the number of bytes available for writing into the buffer (an absolute value). If there is no transmit buffer limit, a maximum-sized integer is always returned.
