IPv6 is a new IP version which is designed for; be an evolutionary step from IPv4. It can be installed as software that can be upgraded to normal on the internet equipment and interoperable with the current IPv4. Dissemination strategy was designed to not have flagdays or other dependency. IPv6 is designed to run well on high performance networks (eg Gigabit Ethernet, OC-12, ATM, etc..) and at the same time still efficient for low bandwitch network (eg wireless). In addition, it provides an Internet platform for new capabilities that will be needed in the near future.
IPv6 includes a transition mechanism which is designed to allow users to adopt and deploy IPv6 to provide direct interoperability between IPv4 and IPv6 hosts. The transition of a new version of Internet Protocol should be incremental, with little or no critical interdependencies, if it is to succeed.
IPv6 Development
- Change from IPV4 to IPV6 mainly on:
o Expanded Addressing Capabilities
o Header Format Simplification
o Increase support for the expansion and selection
o Flowing Labeling Capabilities
o Approval and Privacy Capabilities.
IPV6 Implementation
Implementing IPV6 router and developed for many different host operating systems. Many are now shipping products. These include the implementation of the host: Apple, BSDI, Bull, Digital, epilogue, FreeBSD, FTP Software, Hitachi, HP, IBM, INRIA, Interpeak, Linux, Mentat, Microsoft, NetBSD, Nokia, Novell, NRL, NTHU, OpenBSD, Pacific Softworks , Process Software, SICS, SCO, Siemens Nixdorf, Silicon Graphics, Sun, UNH, and WIDE, and router implementations by 3Com, 6WIND, Bay Networks, Cisco Systems, Digital, Hitachi, IBM, Merit (routing protocols), Nokia, NTHU , Sumitomo Electric, and Telebit Communications.
