IPv6 Tunnel Overview
It is impossible for IPv6 to supersede IPv4 immediately. Therefore,
they will simultaneously exist in the same environment for quite
a long time. A good transition mechanism is needed to provide a
stable transition and minimize the effects on the existing users.
At present, this topic is the main target of the IETF NGTRANS work
group. Many transition mechanisms have been put forward and
some of them have been used for 6Bone. IETF recommends tran-
sition mechanisms such as tunnel technology, Dual Protocol Stack
and network address translation.
IPv6 tunnel technology encapsulates IPv6 packets in IPv4 packets,
so IPv6 packets can be transmitted in IPv4 core network. This is
as shown in Figure 10.
