Detailed Description

(abstract) base class of all UdpSockets


Introspection did not find any typical Config paths.

This class exists solely for hosting UdpSocket attributes that can be reused across different implementations, and for declaring UDP-specific multicast API.


Attributes

No TraceSources are defined for this type.
Size of this type is 152 bytes (on a 64-bit architecture).

Member Function Documentation

◆ GetIpMulticastIf()

virtual int32_t ns3::UdpSocket::GetIpMulticastIf ( void  ) const
privatepure virtual

Get the IP multicast interface.

Returns
the IP multicast interface

Implemented in ns3::UdpSocketImpl.

Referenced by GetTypeId().

◆ GetIpMulticastLoop()

virtual bool ns3::UdpSocket::GetIpMulticastLoop ( void  ) const
privatepure virtual

Get the IP multicast loop capability.

This means that the socket will receive the packets sent by itself on a multicast address. Equivalent to setsockopt IP_MULTICAST_LOOP

Returns
the IP multicast loop capability

Implemented in ns3::UdpSocketImpl.

Referenced by GetTypeId().

◆ GetIpMulticastTtl()

virtual uint8_t ns3::UdpSocket::GetIpMulticastTtl ( void  ) const
privatepure virtual

Get the IP multicast TTL.

Returns
the IP multicast TTL

Implemented in ns3::UdpSocketImpl.

◆ GetMtuDiscover()

virtual bool ns3::UdpSocket::GetMtuDiscover ( void  ) const
privatepure virtual

Get the MTU discover capability.

Returns
the MTU discover capability

Implemented in ns3::UdpSocketImpl.

Referenced by GetTypeId(), and ns3::Ipv4::GetTypeId().

◆ GetRcvBufSize()

virtual uint32_t ns3::UdpSocket::GetRcvBufSize ( void  ) const

Get the receiving buffer size.

Returns
the buffer size

Implemented in ns3::UdpSocketImpl.

static

◆ MulticastJoinGroup()

virtual int ns3::UdpSocket::MulticastJoinGroup ( uint32_t  interface,
const Address groupAddress 
)
pure virtual

Corresponds to socket option MCAST_JOIN_GROUP.

Parameters
interfaceinterface number, or 0
groupAddressmulticast group address
Returns
on success, zero is returned. On error, -1 is returned, and errno is set appropriately

Enable reception of multicast datagrams for this socket on the interface number specified. If zero is specified as the interface, then a single local interface is chosen by system. In the future, this function will generate trigger IGMP joins as necessary when IGMP is implemented, but for now, this just enables multicast datagram reception in the system if not already enabled for this interface/groupAddress combination.

Attention
IGMP is not yet implemented in ns-3

This function may be called repeatedly on a given socket but each join must be for a different multicast address, or for the same multicast address but on a different interface from previous joins. This enables host multihoming, and the ability to join the same group on different interfaces.

Implemented in ns3::UdpSocketImpl.

Referenced by Ipv4FragmentationTest::StartServer().

◆ MulticastLeaveGroup()

virtual int ns3::UdpSocket::MulticastLeaveGroup ( uint32_t  interface,
const Address groupAddress 
)
pure virtual

Corresponds to socket option MCAST_LEAVE_GROUP.

Parameters
interfaceinterface number, or 0
groupAddressmulticast group address
Returns
on success, zero is returned. On error, -1 is returned, and errno is set appropriately

Disable reception of multicast datagrams for this socket on the interface number specified. If zero is specified as the interfaceIndex, then a single local interface is chosen by system. In the future, this function will generate trigger IGMP leaves as necessary when IGMP is implemented, but for now, this just disables multicast datagram reception in the system if this socket is the last for this interface/groupAddress combination.

Attention
IGMP is not yet implemented in ns-3

Implemented in ns3::UdpSocketImpl.

◆ SetIpMulticastIf()

virtual void ns3::UdpSocket::SetIpMulticastIf ( int32_t  ipIf)
privatepure virtual

Set the IP multicast interface.
