Fujitsu Limited

Tokyo, June 27, 2002 - Fujitsu Limited today announced the MB86977, a new system-on-chip (SoC) device designed for high-speed broadband routers to be used in fiber-to-the-home service. The MB86977, which includes a high-speed packet processing engine developed by Fujitsu and its subsidiary, Fujitsu LSI Solution Ltd., enables processes that previously were handled through software, such as packet-destination transfer, to be handled through hardware, thereby achieving full-rate bidirectional LAN-WAN throughput of 100 Mbps, more than double the level of existing broadband routers.

Fujitsu's new chip has the following noteworthy features:

1.

High-speed IP packet processing engine implements the following processes in hardware:

• Packet destination transfer (IP forwarding) based on IP address contained in packet
• IP address and TCP/UDP port number translation (Network Address Port Translation)
• Filtering, to admit or reject incoming packets based on pre-set criteria
• IPv4 and IPv6 support

2.

Handles full-duplex, full-rate transfer at 100 Mbps bidirectionally.

3.

Can handle packet filtering for both LAN and WAN, making it possible to set up zones isolated from the LAN and WAN (DMZ).

4.

Giving priority to output of voice packets over data packets, packet priority control circuitry reduces loss rate due to time lag and delay on streaming data transfers (sound, video).

Development kits in various software environments using the KASAGO TCP/IP core are available from Yokohama-based software vendor Elmic Systems Inc. for quickly and economically developing high-performance 100 Mbps broadband routers.

Utilizing its advanced SoC technology, Fujitsu will continue its efforts to reduce footprint requirements and part counts while expanding its line of high-performance SoCs for home networks.
