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.
