Shunra Software (www.shunra.com) announced today that its test solution
was used by Agilent Technologies Inc. to demonstrate the effects of network
impairments on the performance of stateful TCP traffic generated by Agilent's
N2X solution. The N2X solution validates the performance of next-generation
network equipment for triple play services. The demo proved the importance of
testing network performance using both stateful TCP and real-world network
conditions. It is the only way to accurately assess how network-based
services will perform and impact the user experience.
Shunra's WAN emulation solution provides real-world network and router
behavior by introducing rate-limiting, latency, packet loss and router
queuing schemes into the traffic flow. The results of the demonstration show
that a certain number of bits and packets can move through the network, and
that effective throughput, or goodput, can be dramatically lower when using
stateful TCP traffic deployed in a real-world network with delays, congestion
and queuing effects.
As a majority of Internet traffic today is stateful TCP traffic
originating from e-mail, web-surfing and bandwidth-intensive peer-to-peer
applications, the industry is moving away from basic stateless traffic
blasting and towards a model that validates stateful forwarding performance
at layer 4 and above.
Shunra is the world's leading provider of network emulation solutions.
Shunra Virtual Enterprise (VE) is a highly robust, comprehensive network
emulation solution which creates a virtual network environment in the
pre-deployment network lab. It delivers a powerful, flexible and easy way
to test the performance of applications and network equipment under a wide
variety of network impairments -- exactly as if they were running in a real
production environment. Helping organizations understand the impact of new
technology rollouts on network and application performance, Shunra VE
resolves any related issues before they impact end-users.
"The Shunra Virtual Enterprise solution plays a critical role in
demonstrating the value proposition of our hardware-based stateful TCP
traffic and measurement solution," said Rod Unverrich, general manager of
Agilent's data networks operation. "Using Shunra VE, we were able to
demonstrate the interaction between TCP and real-world impairments such as
delay and packet loss, and various queuing mechanisms, all of which impact a
router's ability to deliver quality of experience. Traffic blasting at L2 or
L3 is simply insufficient in today's networks where subscriber experience is
what pays the bills for service providers."
"We are proud to be working with Agilent Technologies and we view our
involvement in this project as validation of the value our application
performance testing solution provides. Considering their well known supplier
expectation centered on technology, quality, and performance, it is very
meaningful to us that they have selected our product to feature in their TCP
traffic performance demonstration video," said Matt Reid, VP Worldwide
Marketing.
Shunra Virtual Enterprise is the market leader in WAN emulation solutions
for application performance testing throughout the entire application
development lifecycle. Shunra's award-winning solutions enable development,
