- ...realm
- The
term realm [15] is used as it is used
with current NAT, to designate
a collection of interconnected hosts across
which the IPv4 addresses are unique.

- TRIAD is an acronym, originally
standing for
Translating Relaying Internet Architecture integrating
Active Directories but it might also stand for
Time to Rescue the Internet from Address Depletion.

the same as the original Internet architecture.

-
This assumes the gateway already has one such address if the WRAP
RAs communicate over the existing wide-area IPv4 infrastructure.

- ...IPv6
-
One could argue that the
Internet does not actually need more global addresses,
by relying on efficient allocation and NAPT,
given only about 1 percent of the IPv4 addresses are actually in use.
However, this argument makes IPv6 even less compelling
and WRAP is still beneficial for other reasons, such as connecting
private address domains.

motivations for MPLS, efficient IP forwarding, has been eliminated by
the advent of wire-speed hardware IPv4 forwarding engines.

- ...effective
- Conventional
header compression works best on long-lived connections, such as
telnet sessions over dialup links. However, cellular phone data services
have been most successful with short message services,
for which the gains are less clear.

China has approximately 7 million global addresses,
enough to support approximately 500 billion simultaneous connections
using NAT-PT.

-
For instance, a modern hardware router can forward IPv4 packets at
50 million packet per second yet only forward IPv6 in software
at roughly 50 thousand packets a second.
