◆ MulticastJoinGroup()

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

pure virtual

Corresponds to socket option MCAST_JOIN_GROUP.

Parameters

interface	interface number, or 0
groupAddress	multicast 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

interface	interface number, or 0
groupAddress	multicast 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 )

Parameters

loop	the IP multicast loop capability

Implemented in ns3::UdpSocketImpl.

Referenced by GetTypeId().

◆ SetIpMulticastTtl()
