The Hitachi IPv6 Accomplishments

IPv6 is an easily integrated, flexible mechanism, designed to meet theneeds of such emerging markets as handheld personal computers, IP-enabled cellular devices, and high-speed wireless technology.

IPv6 is appropriate for the next generation of Internet protocols for manyreasons: customizable, cost-efficient and easy to integrate, not only does itfulfill the demand for increased IP addresses, it also solves the Internetscaling problem by considerably reducing routing table size.

• Greater levels of address hierar-chy: address space has increasedfrom 32 bits to 128 bits, supportinga much larger number of nodes.

• A simplified header format, forlower overhead and packet pro-cessing costs. Some IPv4 headerfields have been dropped; othersare now optional.

• Dual-stack and configured tunnelsupport ensure a simple transitionto IPv6.

• Quality of Service has been addedto that traffic flow which requiresspecial handling, such as “real-time” service.

• Stateless auto-configuration au-tomatically assigns an IP addressto a host device upon its connec-tion to the network, eliminating theneed for manual configuration oruse of a DHCP server.

• MultiCast functionality supportsbandwidth-intensive applicationssuch as video conferencing, onlinecorporate communication, distancelearning, and software distribution.

• MultiPath functionality allowsstable, even load balancing acrossmultiple hosts.

• Flexible IP address assignments,including IPX and NSAP, provide aneasy-to-integrate, smooth migra-tion to IPv6.

• Founding member of the IPv6 Forum.

• Deployed the world’s first commercial IPv6 network, linking sevenmajor cities in Europe.

• Released the world’s first commercial IPv6 protocol translationrouter (NR60), debuting in Asia.

• Member of the KAME Project:http://www.kame.net

• Member of the USAGI Project: http://www.linux-ipv6.org

• Sponsors of the IPv6 Summit: http://www.ipv6-es.com

• Selected as the IPv6 platform for the Euro6IX Network.

• Continuous IETF leadership; operated the IETF interim meeting(September 1999) with IETF contributions, RFC2767 (BIS).

• Interoperability Testing:- Member of the UNHIOL Testing Consortium.- Connectathon 2000, IOL, TAHI Project:http://www.tahi.org

• Awarded ‘Best of Show’ at the Network + Interop (N+I) 2000, inTokyo. Used as the conference’s external router, the GR2000provided complete IPv6 connectivity at the showcase network event.

The GR2000 delivers excel-lent IPv6 performance, atwire-speed rates. Processedby dedicated Hitachi ASICs,IPv6 packet routing achievesforwarding rates of up to 26Mpps, and OC-48 speeds(2.4 Gbps).

Thoroughly tested, up-to-datefeatures using the KAME stackensure stable, reliable code,while features such as IPv6 fil-tering, tunneling, and QoS pro-vide multiple application support.

IPv4 to IPv6: A Smooth MigrationA key requirement for a successful transition to IPv6 is to maintain full compatibility with IPv4, while implementingIPv6. This allows IPv6 hosts to operate alongside IPv4 hosts over an existing IPv4 infrastructure. The transitionmechanisms should be transparent to end users, easy to administer, and non-disruptive to the network.

The Hitachi GR2000 offers a powerful and intelligent migration strategy from IPv4 to IPv6. The following mecha-nisms ensure a smooth migration:

Dual Stack

The dual-stack approach allows IPv4 and IPv6 networks torun simultaneously within the same box, resulting in a cost-sensitive, simple architecture which both preserves andmaximizes your existing investments.

Tunneling

Tunneling provides a way to use existing IPv4 routinginfrastructures to carry IPv6 traffic. This techniqueencapsulates IPv6 packets within IPv4, so that they canbe routed (tunneled) across an IPv4 infrastructure.

When the IPv6 packet arrives at the end of its tunnel,another dual-stack router or host de-encapsulates thepacket, and re-routes it to its destination.
