| IETF |
Internet Engineering Task Force. The IETF is a
large open international community of network designers, operators,
vendors, and researchers concerned with the evolution of the
Internet architecture and the smooth operation of the Internet.
It is open to any interested individual. The actual technical
work of the IETF is done in its working groups, which are organized
by topic into several areas. Much of the work is handled via
mailing list. The Internet standards-related documents are published
as RFC (Request For Comments). |

| iMode |
Japanese network NTT DoCoMo has had a great deal
of success with iMode, with the main advantage over WAP being
that it is packet-switched network. Thus, it actually runs at
the same speed of connection as WAP, but because the network
is packet switched, it works considerably faster- and in colour. |

| IMT-2000 |
International Mobile Telecommunications 2000.
The ITU initiative for a service that will provide radio access
to the global telecommunications infrastructure, through both
satellite and terrestrial systems, serving fixed and mobile
users in public and private networks. In other words, third-generation
services. |

| IPv6 |
Internet Protocol, Version 6, IPv6 was developed
by the IEFT as a version of the IP protocol. It was accepted
as an internet standard in December 1995 because of work on
IPng (next generation). This version is a further development
of Version 4 (IPv4). The main enhancements are as follows: Extended
addressing options, simplified header format, improved support
for options and extensions, new facilities for defining the
level of service, and improved security procedures. IPv6 has
extended the address space from 32 bits to 128 bits, so that
a significantly higher number of addressable internet nodes
can be addressed, several hierarchy levels are possible, and
the autoconfiguration of addresses is simplified. The IPv6 header
consists of a 4-bit version field for the IP version, a priority
field of the same length for level-of-service attributes, and
a 24-bit flow-label field, which is used by the data source
to identify data packets that require special handling with
a specific level of service. |
