Detailed Description

This class implements Linux struct pktinfo in order to deliver ancillary information to the socket interface.

This is used with socket option such as IP_PKTINFO, IP_RECVTTL, IP_RECVTOS. See linux manpage ip(7).

This tag in the send direction is presently not enabled but we would accept a patch along those lines in the future.

Member Function Documentation

void ns3::Ipv4PacketInfoTag::Deserialize ( TagBuffer i )

virtual

Parameters

i	the buffer to read data from.

Read the content of the tag from the provided tag buffer. DO NOT attempt to read more bytes than you wrote with Tag::Serialize.

Implements ns3::Tag.

Here is the call graph for this function:

Ipv4Address ns3::Ipv4PacketInfoTag::GetAddress ( void ) const

Get the tag's address.

Returns: the address

Definition at line 48 of file ipv4-packet-info-tag.cc.

References m_addr, and NS_LOG_FUNCTION.

TypeId ns3::Ipv4PacketInfoTag::GetInstanceTypeId ( void ) const

virtual

Returns: the TypeId associated to the most-derived type of this instance.

This method is typically implemented by ns3::Object::GetInstanceTypeId but some classes which derive from ns3::ObjectBase directly have to implement it themselves.

Implements ns3::ObjectBase.
