Packet communication system over IP network

摘要

In recent years, computer communication systems have been changing from proprietary architecture to open (Transmission Control Protocol/Internet Protocol: TCP/IP) architecture. In line with this trend, the Japan Agricultural Cooperatives (JA) system is changing from the legacy mainframe-centric system to the TCP/IP system. Although the AX series are Toshiba's best-selling X.25 packet switches, in order to rapidly respond to this market trend we have developed a next generation system called the GX series. The GX series uses TCP/IP as a foundation and offers a better price-performance ratio than the AX series. The GX series is expected to be well accepted by customers who wish to migrate from the legacy X.25 system to the more cost-effective TCP/IP-based system.
