Established in 1950, the China
Academy of Railway Sciences
has transformed from a state
institution into a large-scale
technology enterprise under
the Ministry of Railways,
integrating various activities
including research and
development,manufacturing
and consultation.
Set up to promote the scientific
progress of China's railways,
the Academy today focuses on
new technology for building
high-speed track, heavy-load
transportation, information
services, security, the
modernization of railway
equipment and urban railways.

The China Academy of Railway Sciences
is a leading technology enterprise,
responsible for the scientific progress of
China's railway systems. Its important
functions include the construction of
new high-speed rail lines, research into
heavy load rail transportation, advanced
information systems to support the
efficient management and
modernization of China's railways.
In 1998, the China Academy of Railway
Sciences installed a local area network
incorporating the most advanced 155Mb
ATM technology available at that time.
The original network was a great help to
research and office automation, and
improved the overall efficiency of the
organization, but in 2005, the 155Mb
backbone network was struggling to
cope with demand and the academy
decided to invest in a new high-speed
network provided by ProCurve
Networking.
The new infrastructure is built around a
ProCurve 6400 10-Gigabit Ethernet
backbone and four ProCurve 3400-24G
convergence switches, using 10-Gigabit
single-mode optical fiber and 10-Gigabit
multi-mode optical fiber,with 1Gbps
access at the desktop. The new highperformance
network provides dramatic
productivity gains, better protection
from virus attacks and greatly improved
price-performance.

After several years of analyzing
throughput, the Academy had a clear
understanding of network demand, and
knew that it needed a high-speed,
intelligent network with an emphasis
on price-performance, simple
management and reliability. The old
network also faced regular virus
attacks, which slowed down
performance and added to costs. Based
on this experience, the Academy drew
up a "wish list" with the following
specifications for the new network
solution.
- High Speed: A 10-Gigabit Ethernet
backbone with 1Gbps access for
desktops
- Intelligence: Layer 3 managed
switches for access control and to
block the spread of viruses
- Simplicity: Routers and intelligent
processing to be handled at the
convergence layer, with the core layer
only responsible for switching
- Reliability: All components must have
comprehensive guarantees, supported
by convenient after-sales service and
maintenance
- High cost-performance: Chosen
solution should demonstrate costcompetitiveness
and guarantee good
return on investment

The new network is built on a threelayer
structure, including the core layer,
the convergence layer and the access
layer, with a 10-Gigabit Ethernet
backbone and 1Gbps access for
desktops. The core layer has a ProCurve
6400 10-Gigabit switch, connected to
four ProCurve 3400-24G convergence
switches via 10-Gigabit single-mode
optical fiber and 10-Gigabit multi-mode
optical fiber which also enables the
servers to guarantee 1Gbps access to
desktops.
The convergence switches are
connected via 1Gigabit switches at the
access layer using 1Gigabit single-mode
optical fiber, 1Gb multi-mode optical
fiber and twisted-pair cables.
All equipment supports three-layer
router switching. Such a design reduces
the load on switches at the core layer
and speeds up communications
between different nodes. The 1000M
twisted-pair cables provide 1Gbps
access to desktops.

By implementing ProCurve's Adaptive
Edge Architecture (AEA) architecture,
with intelligent access at the edge, the
6400 switch does not need to process
all the data from routers and access
control lists, enabling faster switching
at the core layer.
After one year in operation, the
network has performed extremely well.
While the old network failed to defend
the organization against virus attacks,
the Academy of Railway Sciences has
had no need to deal with virus attacks
since the new network is in place.
With network speed greatly improved,
the Academy has been able to deploy
more than 10 new management
information systems, various scientific
research data inquiry systems and a
new 10-Gigabit iSCSI network storage
solution, all of which have greatly
enhanced work productivity and
organizational efficiency.
The ProCurve AEA architecture provides
intelligence at the network edge that
enables the Academy to balance the
load and protect the network from
viruses, significantly improving overall
network performance. Although this
means the need for more access
switches, it reduces total investment
because the new single-function core
switch replaces the previous, more
costly multi-business core switch.
The Academy also found that
ProCurve's lifetime warranty is a good
guarantee of return on investment by
eliminating concerns about hardware
failure and replacement. The lifetime
warranty is an important factor when
considering the cost-competitiveness of
the ProCurve solution against rival
solutions.
