- Spirent Data Center Testing Solutions Deliver the Industry's Only 
Unified Layer 2-7 Test Architecture for High Performance Virtualized,
Eco-Friendly Networks

Spirent Communications plc (LSE: SPT), a leader in networks, services and
devices testing, announces the industry's first holistic approach to
validating the performance of tomorrow's dynamic data centers. This approach
offers a unified Layer 2-7 test architecture specifically designed to test
the end-to-end performance of 10/40/100 Gigabit Ethernet fabrics, Fibre
Channel over Ethernet (FCoE) convergence, virtualized server networking,
cloud computing-based applications and security. Spirent was recently
recognized by Frost & Sullivan as the leader in enterprise network test and
measurement solutions for research and evaluation labs.

Tomorrow's data centers are being designed around virtualized services
and converged networks. These designs set new standards for network
performance and scale, service availability, system security, application
Quality of Experience (QoE) and power efficiency, which are only validated by
a holistic test architecture. Trusted by the world's leading network
equipment manufactures, Spirent's data center test architecture includes:

- Spirent TestCenter(TM): An award winning modular layer 2-7 performance
      test platform, Spirent TestCenter validates Quality of Service (QoS) 
      and QoE of converged data center networks including FCoE with Converged 
      Enhanced Ethernet (CEE) and Data Center Ethernet (DCE)

    - Spirent TestCenter(TM) Virtual: A Best of Interop Finalist for 2009,
      Spirent TestCenter Virtual extends the capabilities of Spirent 
      TestCenter to measure the true performance impact of virtualized 
      servers, switches and appliances in tomorrow's data center networks

    - Spirent TestCenter Hypermetrics(TM): The award winning Spirent
      TestCenter Hypermetrics(TM), expands Spirent TestCenter performance to
      emulate the most realistic data center infrastructures with a 
      multi-core, multi-dimensional HSE (10/40/100GbE) module that enables
      stateful, line-rate, layer 2-7 multi-play scalability at terabit 
      capacities

    - Spirent TestCenter(TM) Avalanche: The market leading Spirent TestCenter
      Avalanche is designed to validate network security, server load 
      balancing and WAN acceleration while loading the data center 
      application services including the Storage Sub System with NFS and CIFS

    - Spirent TestCenter GreenPut(TM): An innovative approach, Spirent
      TestCenter GreenPut benchmarks the energy efficiency of deployed or
      soon-to-be deployed data center systems by measuring the throughput per 
      watt of network elements, and calculating the power consumed under 
      various traffic and session load

    - Spirent TestCenter NoCode(TM): A fourth-generation visual programming
      environment, Spirent TestCenter NoCode, enables every test engineer to
      develop meaningful and repeatable test cases that more easily and more
      quickly finds defects with fewer test runs

    - Spirent TestCenter(TM) OnDEMAND: By leveraging a team of testing
      experts working both on and off-site, Spirent TestCenter OnDEMAND 
      validates all aspects of a data center to detect and mitigate 
      performance, security, and scalability problems before the launch of 
      new or advanced infrastructure and applications



"Market conditions are accelerating innovations around data center
performance, scalability, security, and power efficiencies," said Bill Burns,
CEO at Spirent Communications. "Spirent's holistic, unified test architecture
enables today's innovators to achieve their vision of building and deploying
tomorrow's dynamic data centers."

Spirent's holistic data center testing architecture will be on display at
Interop 2009 at Spirent Booth #1051. The solutions will also be showcased at
the Spirent Proof of Concept (SPoC) Labs and Collaboration Centers in
Beijing, London and Sunnyvale. For more information visit www.spirent.com or
