The commercial use of the Internet has rapidly spread as a communication infrastructure. But IP (Internet protocol), which is a basic technology of the Internet, cannot keep up with this rapidly expanding market. Especially, a lack of IP addresses is a serious problem. There is a prediction that the IP addresses will be exhausted within several years. To solve this problem regarding lack of IP (IPv4) addresses, a next-generation Internet protocol “IPv6 (Internet protocol version 6),” which has been standardized by the IETF (The Internet Engineering Task Force) as a succession of IPv4, has been developed. Supported by the recent trend toward broadband/always-on connection, the movement towards commercial use of IPv6 is becoming more and more active. To respond to this trend, Hitachi has developed IPv6-supportive functions for its current gigabit router. In September 2001, it was upgraded to provide the same functions as on IPv4 but on IPv6; IPv6 packet transfer and filter/QoS (quality of service) control function. Furthermore, a new model for enterprise use was added. It provides expanded MPLS (multiprotocol label switching), IP-VPN (IP virtual private network) functions as well as an improved user interface.
