HITACHI Announces Two GR2000 B Model, High-performance,
Compact Routers for Broadband Services
—The world’s fastest class IPv4/IPv6 packet-forwarding of approximately 1 million packets/s in a 1U-sized*1 router—
HITACHI, Ltd. has developed and will begin selling two new GR2000 B model routers, sales of which start November 30th in Japan. The GR2000 B routers feature an 1U-sized compact form and high-performance routing for broadband services which are being rapidly introduced by businesses and local governments. Furthermore, the new routers inherit the architecture of the current GR2000 series, and thus support the most advanced QoS functions as well as providing a IPv4/IPv6 routing performance (1 million packets/second) that ranks among the world’s fastest for a 1U-sized router.

Currently, the introduction of wide-bandwidth applications , such as the World Wide Web, has been on the rise among businesses and local governments, and the use of broadband services offered by carriers, such as IP-VPN, wide-area Ethernet, and local IP exchange, has been expanding, not only in urban areas, but also among rural communities. In addition, the need for such new features as communication quality management, IPv6 support and security assurance, as well as a demand for higher reliability, has been rising with the increase in the advanced use of networks.

To meet these demands, Hitachi decided to develop and release these two 1U-sized GR2000 B, high-performance routers that offer excellent price performance, for small-to-medium sized remote facilities of companies and governmental organizations.
As the low-end models of the current GR2000 series, these new routers inherit the same hardware architecture and software used by the current GR2000 series, which were launched as Japan's first domestic gigabit routers in February,1999. This ensures the new routers will have the same stable, reliable operation attested to by the thousands of current GR2000s in service. With the addition of the two new models to the current -2S, -4S, -6H, -10H and 20H models, the GR2000 series comprises a lineup of seven models.. This enables the construction of extensive advanced networks ranging from carriers and ISP backbones to enterprises and government offices , all based on the GR2000 series.

Pricing and Availability


1. Small Size and High Performance
Hardware-Based Routing. Allows a forwarding rate of approximately 1 million packets/second, which is almost 100 times the rate of small routers using software-based routing. As other functions, such as QoS control, or filtering and packet-forwarding, are also implemented in hardware, it is possible to construct low-delay/high-speed networks in the actual environment where broadband services are used.
Supports High-Speed Lines. Implements high-speed networks, such as Gigabit Ethernet and ATM OC-3.
Dynamic Routing. Uses the GR2000 routing program, with its extensive record of achievement in the area of large-scale networks. The routing protocol supports RIP, OSPF, BGP4 and Multicast, and can be applied to various networks to enable stable network operation.
Small and Compact. Packaged in a 1U size, the GR2000 B saves space and offers flexibility in rack mounting.

2. IPv6 Support
High-speed IPv6 routing is implemented in hardware. The new GR2000 B is the world’s smallest router to have IPv6 hardware-based routing.
Supports the latest IPv6 routing protocols, such as RIPng, OSPFv3, BGP4+ and PIM-SM (IPv6 multicast protocol).

Shifting to IPv6 networks is done easily due to IPv6 shifting support features, such as dual-stack IPv4/IPv6 and tunneling, which are pre-installed in the GR2000 B. These features have already been proven on the current GR2000 models.

3. Broadband-Support Functions

Packet-Shaping on Ethernet. Required bandwidth can be allocated for each of several addresses on the Ethernet port connected to the wide-area LAN services. Furthermore, the minimum bandwidth can be secured for each application within this bandwidth.
GFR*2 on ATM. The partial speed-securing service of ATM makes it possible to store important packets such as those relating to buckbone fanctions, in the speed-secured bandwidth (shaping).
PPPoE*3. Support is PPPoE, which is used in various broadband services, including optical access services.

  1. U: Unit 1U(unit) is approximately 44.45 mm
  2. PPPoE: Point-to-Point Protocol on Ethernet
  3. GFR: Guaranteed Frame Rate

Ethernet is a product name of Xerox Corporation.
