Service Providers in China Select Cisco's Optical Internetworking Strategy to Build New World Networks

SAN JOSE, Calif.--(BUSINESS WIRE)
Cisco 12000 GSR Provides Critical
Component in China's
Internetworking Capability
Cisco Systems today announced that it is
enabling service providers in China to
reengineer their networks for
next-generation optical internetworking
while empowering the country to build a
stronger backbone network.
Service providers in China are selecting
the Cisco 12000 Gigabit Switch Router
(GSR) series to build out New World
Networks optimized for data, voice and
video. The Cisco GSR is the critical
component to Cisco's optical
internetworking strategy to build
networks that run IP directly over the
optical layer.
Prominent service providers in China
already deploying Gigabit Switch Routers
include China Telecom, Shanghai Online,
Guangdong CATV and Dalian CATV who
will be among the first in the world to be
able to harness the power of optical
internetworking.
"Service providers in China clearly
recognize the advantages of optical
internetworking," said Graeme Fraser,
general manager of the Optical
Internetworking Business Unit. "These
service providers are building networks
that will ensure China's significant role in
the Internet economy. "
Today's public networks use older
time-division multiplexing (TDM)
technology, which forces all types of
traffic into connections aggregated from
64 kbps voice channels. In the optical
internetworking world, much of this
traditional equipment becomes
unnecessary due to gains afforded by
statistical multiplexing.
By statistically multiplexing packets and
cells over wavelengths in the optical
network layer, switches and routers can
provide increased bandwidth efficiency
and eliminate substantial cost and
complexity. The result is a more flexible
network that can carry data, voice, and
video.
China Telecom
China Telecom, the national
telecommunications carrier, has rolled-out
a network centered around six GSRs
working into a pan-China IP backbone.
ChinaNet ("163 network") is the country's
largest Internet access network and
covers 30 provinces. The current
ChinaNet backbone upgrade program was
initiated at the beginning of this year.
Following the implementation of new
capabilities at the national level, each
province in China will begin building up
their own local backbone networks.
Beijing, Shanghai and Guangzhou are key
cities where demand is highest for
IP-based multiservice networks. As hubs
for regional trade and communications,
these cities need high-bandwidth, reliable
and secure infrastructures as
development continues to accelerate. For
that reason, China Telecom selected
Cisco GSRs to carry the load at these
strategic hubs.
Shanghai Online
Shanghai Online, the Internet service
provider for one of China's most
progressive municipalities, also has
selected Cisco Systems as its technology
supplier for its next-generation backbone.
Shanghai Online deployed the GSR into its
backbone enabling it to roll out a
Packet-over-SDH (Synchronous Digital
Hierarchy) capability that can send IP
packets over SDH equipment.
Guangdong CATV
Guangdong CATV, one of the largest
cable television stations in China, is
implementing Cisco 12008 Gigabit Switch
Routers in its backbone network. The
network will provide integrated MPEG2
video, H.729 audio and LAN data traffic
over a single IP platform to more than
400,000 subscribers in 21 cities in
Guangdong province. These GSRs are part
of an end-to-end Cisco solution that also
includes high-end routers and remote
access servers.
The Cisco-based solution that Guangdong
CATV has will enable the station to
optimize bandwidth utilization over its
existing high-speed SDH optic fiber
backbone.
"We selected Cisco Systems over its
competitors because it was able to
demonstrate the level of support and
performance we needed," said Wang
Chang Li, president of Guangdong CATV.
"We have ambitious plans to offer a
variety of multimedia value-added
services to our cable TV subscribers, so
we demand tremendous new functionality
and higher performance from our
networking equipment. Cisco's
end-to-end packaged service and
hardware provides us with the kind of
total solution that is essential for a
reliable and scalable network."
Dalian CATV
Dalian CATV also is installing the Cisco
12008 Gigabit Switch Router into its
backbone network and transmitting data,
voice and live video throughout the city
of Dalian. The network covers 16 branch
nodes in the city, which are connected
by SDH equipment.
Cisco 12000 Gigabit Switch Router Series
The Cisco 12000 GSR series of routers are
the company's next-generation range of
Internet routing products targeted at
Internet service providers (ISPs), carriers
who provide Internet services, Internet 2
and next-generation network applications
and high-speed enterprise WAN
backbones. |
