GTS facilities in RTH Tokyo -Conceptual design- • Central telecommunication facility in JMA was fully replaced in October 2005. • The new GTS switching system is composed by two UNIX servers in a cluster. Message/File Switching System UNIX Operating system CPU 1.9GHz X 4 Message editing Fax format conversion Memory 8GB cluster control Back-end system BUFR encode & decode Shared disk WMO monitoring UNIX Operating system GTS links CPU 1.9GHz X 4 Memory 8GB Major functions supporting GTS operations + Message and Fax exchanges by both socket and so-called batched ftp through GTS + File exchanges by ftp through GTS + Collection of observational data by e-mail via the Internet NWP system Intranet systems Interne t 14. JMA Internet Connection • Multi-homed connections to Internet with two dedicated links since 2001 • Two 20 Mbps links in operation: one since February 2005, the other since March 2006 Internet ISP #1 20Mbps JMA Intranet ISP #2 Multi-homed connections for reliability 20Mbps Packet Shapers Router Controllers Firewalls ISP #1 Load Balancer DMZ FTP Servers Public Servers ISP #2 2007 2008 Thank you
