Highlights
Force10 Networks’ proven
line-rate performance and
high-availability features enable
NTT-ME to cost-effectively
upgrade its core network in
preparation for increased traffic
and advanced IP services.
With the increase of IP phone and streaming
services, ISP preferences and standards are
changing rapidly. Cost and speed are becoming
more important factors than ever, balanced by
the ongoing need to maintain stable connections
and predictable service levels. As traffic continues
to increase, it’s clear that service providers all
over the world are facing new challenges in
adding affordable speed to their networks
while maintaining the switching performance
necessary to achieve customer satisfaction.
These are the reasons NTT-ME selected the
Force10 Networks E-Series E600 resilient
switch/router. The E600 achieves a 10 Gigabitsper-second (Gbps) line rate, as well as nonblocking performance on all ports for all packet
sizes, including jumbo frames. The result is zero
packet loss hitless forwarding in a redundant
configuration, with security, reliability and
speed that now makes it possible to provide
customers with very high levels of performance
and satisfaction.
Handling Increased Traffic
Without Sacrificing Availability
In making its switch/router choice, NTT-ME
established a number of criteria necessary for
creating a differentiable service offering and
gaining a competitive advantage. These included:
• Correspondence to traffic—which increases
by two fold every six months
• Leading-edge performance capable of
achieving 10 Gbps line rate and non-blocking
performance on all ports, for all packet sizes
• 99.999% service uptime to maintain and
improve customer satisfaction
The Backbone: High Capacity
and Reliability
By integrating the Force10 Networks E600
switch/router, NTT-ME now offers large business
enterprises a total solution brand. Known as the
Xephion, the NTT-ME solution offers a massive
10 Gigabit class backbone and Internet connectivity exceeding 7 Gigabits. And with availability
rated at 99.999%, more than 600 customers can
now place their trust in the system.
NTT-ME provides a broad range of services to
meet customer needs, taking advantage of a
huge capacity and highly reliable backbone.
The XePhion Internet VPN is one such service.
It achieves affordable intracompany networking
for up to thousands of points, with high-speed
performance and outstanding reliability. At the
same time, NTT-ME provides unitary outsourcing
services ranging from construction to maintenance
and operation. NTT-ME also provides networks
corresponding to various customer needs by
selecting from an abundance of optional services
that include VPN and VoIP hybrids, combining
L2/L3 services.
"We utilize the backbone broadly and provide
many Internet access services for ISPs and
carriers as a total solution," said Mr. Toshiaki
Imai, NTT-ME’s Internet Solution Division
Manager at XePhion Project Headquarters.

“We utilize the
backbone broadly and
provide many Internet
access services for ISPs
and carriers as a total
solution.”
Mr. Toshiaki Imai
NTT-ME’s Internet Solution
Division Manager,
XePhion Project Headquarters
"These include ISP projects for consumers
such as second-level provider, CATV Internet,
Internet-ready apartment, wireless LAN spot or
iDC. By dealing with such projects broadly, we
can flexibly respond to various company needs
— not only in the business-to-business and
business-to-consumer arenas, but also extending
to business-to-business-to-consumer as well."
Speed, Security and Stability
NTT-ME’s consumer-oriented Internet access
service that shares and provides the backbone
network for XePhion is known as WAKWAK—
which has consistently obtained superior
results in provider research compiled by various
business magazines.* The most critical requirements are reliability and consistent speed—
regardless of the amount or type of traffic on
the network. In response to this requirement,
NTT-ME has been trying to reinforce WAKWAK’s
capacity as much as possible, corresponding to
customer growth.
"Although we haven’t implemented such a
large-scale expansion in advertising, the number
of our customers is increasing steadily," said
Mr. Masafumi Hayashi, assigned to strategy
development for WAKWAK. "The quality
connection service has spread by word-ofmouth. It seems that we’re being chosen
by customers who are able to notice the
difference in quality."
In the spring of 2003, further reinforcement
of the band of a backbone network became
necessary when traffic doubled in the Internet
field within six months. Although the network
was then configured with devices centering on
the 1 Gigabit level, the increase in traffic
required the network to have a 10 Gigabit base.
Two sets of core switches were set as the target
for replacement, at a time when switch/routers
supporting 10 Gigabit were being introduced
to the market. At that point, NTT-ME started to
review offerings from various vendors.

“But given the
redundant configuration
of the E600, even if
one side stops, it
switches instantly.
This hitless forwarding
was a function that
was indispensable
to WAKWAK.”

The Point of Choice: Guaranteed
Line Rate
After engaging in device demonstrations,
charging the expected load and carefully
repeating verification, NTT-ME chose the
Force10 E600 switch/router. "The point of choice
was a guaranteed line rate," said WAKWAK
backbone technical engineer Mr. Taichi Igarashi.
"Although there were several vendors who
had announced 10 Gigabits in their catalog
specifications, we discovered that if the load
was charged, performance fell significantly.
In that respect I was sure the Force10 E600
could maintain the stable capacity and fully
respond to rapid increases in traffic."
Easy Operability and Outstanding
Availability
In March of 2004, NTT-ME shifted its focus to
preparing for installation requirements, as well
as setup/adjustment operation after the model
selection. Operation began just three months
later. "The outstanding support and operability
of the E600 were appealing," said Mr. Akihiro
Koyama, the backbone technical engineer in
charge of the operation. "In cooperation with
the distributor, Force10’s engineers responded
immediately to our needs. It was easy to memorize the operating instructions, and shifting from
the conventional model and implementing the
corresponding patch went well."
The E600 has a per-slot capacity of 56 Gigabits/
second. In addition, when the interface is
subsequently supported from 40 to 100 Gigabits,
line rate can be realized without exchanging the
chassis, thereby eliminating the need for reinvestment. This is due to Force10’s patented fully
passive copper backplane, which has been tested
to support 5 Terabytes-per-second (Tbps) speeds.
The E600 is equipped with the functionality and
architecture of a router, enabling it to be used as
a switch that provides excellent redundancy and
performance. "In this case we applied the E600
as the core switch, but if it can be approved for
use as an access router or a border router by
several verifications, we want to apply it. We’ve
been achieving an availability rate of 99.999%
or more. It’s very attractive that bandwidth and
reliability can be reinforced with excellent
cost/performance," said Mr. Igarashi.
The Force10 solution’s excellent reliability was
valued — particularly since core switching is
used not only for WAKWAK, but also for Internet
connectivity in serving NTT-ME’s corporate
customers. "If an IP phone and streaming are
carried out, hits will affect quality," said backbone
technical engineer and deputy chief Mr. Kazuomi
Kurai. "But given the redundant configuration of
the E600, even if one side stops, it switches
instantly. This hitless forwarding was a function
that was indispensable to WAKWAK."
"In the world of the Internet, new technologies
appear quickly, one after another," Mr. Imai
concluded. "NTT-ME participates in experiments
such as Ubiquitous and IPv6, which enable us to
lead the industry. Through a wealth of technology
and a quality network, we seek to continue to
provide customers with services that ensure high
satisfaction. And Force10 Networks is helping
us to do that."
