Detailed Description

This class implements a tag that carries socket ancillary data to the socket interface.

This is used like socket option of IP_PKTINFO/IPV6_PKTINFO in RFC 3542

See also SocketIpv6TclassTag and SocketIpv6HopLimitTag

This tag in the send direction is presently not enabled but we would accept a patch along those lines in the future. To include the nexthop in the send direction would increase the size of the tag beyond 20 bytes, so in that case, we recommend that an additional tag be used to carry the IPv6 next hop address.

◆ Deserialize()

void ns3::Ipv6PacketInfoTag::Deserialize ( TagBuffer i)
overridevirtual
Parameters
ithe 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.
