Policy of Hitachi’s activities on IPv6

Smooth Migration solution – IPv4-IPv6 connectivity– Existing applications over IPv6– Minimize cost to early adopter

Interoperability ready Stability,reliability for business backbone Preparation to “Next Stage”


Hitachi’s activity about IPv6 (1) Hitachi has been developed IPv6 routers for 5 years. Early stage (1996-1997) interoperability testing in UNH. Hitachi NR60 router, a frontier product of IPv6.

– IPv4, IPv6, BGP4+, IPv4-IPv6 Protocol translation, IPsec etc. Toolnet6 is distributed as free software by Hitachi.

– Driver software to support IPv6 on Windows95/98 PCs. IETF contribution. e.g. RFC2767(Bump-in-the-Stack). A member of KAME project. A member of IPv6 Forum


IPv6 Software for Windows (Toolnet6)• A tool Software to use existing Windows(R) applications over IPv6.

• Enhancement on Network Interface Card driver software

• Free distribution from Hitachi home page http://www.hitachi.co.jp/Prod/comp/network/pexv6-j.htm

• RFC2767(Bump-in-the-Stack)

Hitachi’s activity about IPv6 (2) Gigabit router GR2000 IPv6 software has been released fo

r trial networks.– More than 50 units of GR2000 are used in IPv6 networks

Highlight: Networld + Interop 2000 TOKYO.– At the Showcase Network, connecting with MicroSoft, Cisco etc.

– GR2000 was used as a IPv6 external router.

– The grand prize in the section of carrier infrastructure construction product.

– RFC2465,2466,2452,2454:MIB

– etc.


GR2000 (Current: IPv4+IPv6) Software Upgrade Solution for early adopters

• IPv4 packets are forwarded by Hitachi proprietary hardware.

•Main Processor forward IPv6 packets

• IPv6 forwarding is based on software with some hardware logic.

• No performance penalty to IPv4 network• Low cost to start for early adopters with investment protection

• Flexibility to add IPv6 additional functions

Issues: for the next stage “Always-on” explosion will come 2002-2003 Mobile

-phone (with video data), World-Wide-Wireless– Broadband video-data stream on IPv6 network

What happen ? What need ? (to routers)– High speed forwarding and QoS, like IPv4 or more!

– High speed Security

– High speed load balancing for huge “Internet Data Center”

Hitachi has started development for the next stage, “B to H” concept data-center router.

– Broadband to Home– Business to Home


What is difference between “B to C” and “B to H”

Just my definition,

B to C (IPv4 based):– Consumers intentionally access the Internet. e.g.”trading”– Access traffic is not so heavy, even if “Always-on”.– Almost consumers will be moderate to access the Internet.

B to H (IPv6 and “Always-on” based):– Almost people access the Internet without intention of

“network access”. e.g.”TV watching”,”Bi-directional game”– Sometimes, tremendous traffic will be generated.– Some people may make damage on the network system with

a malicious intent.


Requirement for “BtoH” to routers

• Hi speed load balance• High speed encryption/decryption• Discarding malicious heavy traffic• etc

• High speed IPv6 packet forwarding• High speed IPv6 QoS• High speed and high density of line interface • etc.

System-oriented requirement Fundamental requirement

Internet


As a member of the “Super Internet Project”

“Super Internet Project” is one of Japanese government projects for IT strategy.– anyone,anytime,anywhere,as much as ... – MPT/TAO project

As a member of the “Super Internet Project”, Hitachi has started to develop new router technology for the B to H “System-oriented requirement”.

Also, Hitachi has already started to develop router enhancement for the “Fundamental requirement” as a high speed router vender.


Conclusion Hitachi has been one of the leaders of IPv6 developm

ent and deployment community. More than 50 units of GR2000 have already been use

d in our customer trial networks. Hitachi has started to development for the next stage of IPv6, especially router technology for “B to H” concept network.

Thank you !
