of the second gateway, and the IPv4
address of the second gateway is a compressed IPv4 address. When the
second gateway is connected to multiple second terminals and the first
terminal needs to send an IPv6 packet to any one of the multiple second
terminals, a destination IPv6 address of the IPv6 packet includes the
IPv4 address of the second gateway, where with a same part of a same
operator network being omitted, the IPv4 address is a compressed IPv4
address.

[0064] The first gateway encapsulates the IPv6 packet in an IPv4 packet,
where a destination address of the IPv4 packet is the IPv4 address
included in the IPv6 address.

[0065] Because what is between the first gateway and the second gateway is
an IPv4 network, and the IPv6 packet cannot be transmitted directly, the
IPv6 packet needs to be encapsulated,Mahaletchumy Arujanan
