GTS
GTS(Global Telecommunication System) is the key component of WMO WWW(World Weather Watch) program
3 layers: Main Telecommunication Network(MTN), Regional Network, and National Network
MTN is the Kernel of GTS, interconnecting 3 World Meteorological Centres, and 15 regional telecomunication centres
8
GTS - Means of communication
point-to-point circuit: surface, ocean, and satellite links
multipoint-to-point: Data Collection Platform(DCP) of Meteorological Satellite
point-to-multipoint: satellite-based data broadcasting, radio facsimile broadcasting
Global, regional, national centres exchange of observation and product data

CMNET - China Meteorological NETwork(sWAN)
Project code named “9210”, means approved in October, 1992
CMA’s national meteorological operational information network
1993-94 overall design, selecting of key technology 1995- 96 pilot system 1997-1999 full scale application software development;
equipment deployment, trial-operation 2000 operation started in Jan.
13
CMNET - Components
Asiasat-2, Ku band transponder VSAT based TCP/IP network
1 hub station, 31 provincial stations, 300 small stations; data rate 512Kb/s (outbound) and 8*128Kb/s(inbound)
Satellite telephone network PCVSAT data broadcasting network
with more than 2000 receiving stations, total data rate: 2 Mb/s
14
CMNET - Application software
3 Functional subsystems: data exchange, database, and operation supervision
developed by a single team for different levels of weather centres, centralized technical support
3 different types of computers: IBM RS6000, DEC ALPHA、 PC

CMA‘s Campus Network( LAN)
History of LAN
1989, implemented CDCNET and DECNET(10Mbps Eth
ernet) with installtion of CYBER main frame and VAX
1989,using 50Mbps Local Couple Network(LCN) connec
ting CYBER and M360 and VAX and IBM main frame ,forming a heterogenous main frame network
1995, implemented 100Mbps FDDI instead of LCN
20
CMA‘s Campus Network
2001, gigabit Ethernet implementation Gigabit/s Ethernet L3switching, CISCO switch connecting all office buildings in CMA’s h
eadquaters4Gbps between core switchs2Gbps form office builldings to core switch100Mbps for desktop
Internet connection: 10Mbps
