iTrinegy Network Emulators are enabling companies to conduct realistic pre-deployment teting of applications that will work in the WAN, MPLS, Wireless, Satellite, Radio, Cable, (A)DSL or Cloud Networks.

iTrinegy, the Networked Application Performance Lifecycle™ experts, announced today that several businesses have chosen iTrinegy's network emulators over competing offerings. iTrinegy's award winning network emulators enable companies to conduct realistic pre-deployment testing of applications that will need to work in the WAN, MPLS, Wireless, Satellite, Radio, cable, (A)DSL or Cloud Networks.

Customers such as the international marketing service consultancy Dunnhumby is among those that have helped iTrinegy consolidate its position as a world-class provider of network emulation products.

"There are many varied and unique issues that will impact an application when deployed onto a real-world network. Helping to eliminate deployment failure and increase application resilience and performance is why our customers turn to us. Dunnhumby recognised that through utilising our network emulation technology they were able to save on time, costs and were able to maximise the efficiency of their networked applications," said Frank Puranik, Product Director, iTrinegy. "Today we are seeing more and more companies placing applications across a variety of networks, and with the added growth of consolidation and cloud computing, the adoption of emulation technology to ensure the success of the networked applications seems assured."

Comprehensive portfolio shapes customer choice
Since their introduction in 2002 iTrinegy Network Emulators are becoming the product of choice for many leading businesses. iTrinegy now offers the most comprehensive portfolio of network emulators in many different combinations from hardware to software solutions which match the needs of customers world-wide.

Dave Duncan, Group Network & Communications Architect, working out of the UK offices of Dunnhumby, specialises in making sure the applications used by their business work optimally. While new applications for Dunnhumby are initially tested and used on the LAN (Local Area Network) they often performed well, but once out on the WAN (Wide Area Network) it was a different story. Some of the applications being rolled out were not performing properly and experienced issues due to network conditions such as latency, packet loss and bandwidth restriction. Dave knew from past experience that the best way to understand what was going on was to see for himself how the applications would perform, in advance of their deployment by emulating the WAN environment.

Dave and his team set up a test environment emulating the network between the UK, India and the US and, having purchased INE Enterprise from iTrinegy, they were able to reproduce the network conditions being experienced by the applications. It was successful as, through scenario testing, they were able to identify the application issues caused by the WAN.

INE Enterprise hasn't just been utilised for new applications, today they continue to test their most important applications to make sure they continue working well. One of the reasons for this is that to customers of Dunnhumby, access world-wide is essential and offering a 24x7 high-quality service is vital.

By using INE Enterprise to emulate the WAN environment, Dave and his team have been able to reproduce the scenarios experienced by applications that were experiencing specific problems. "One area that was problematic for us was the behaviour of PDFs and PowerPoint files across a WAN. We noticed they were often slow, sometimes taking up to 90 seconds to open," said Dave "It's not just a matter of throwing bandwidth at the problem, iTrinegy's network emulator was able to replicate how the applications would perform with more available bandwidth and it didn't make them go any faster!" Dave continued "Through thorough testing with iTrinegy's emulator we were able to see why our PDFs and PowerPoint files were having issues and were able to come up with an alternative solution to overcome the problem."
When asked why they chose iTrinegy Dave said "One of the main reasons we purchased INE Enterprise is that we wanted a product that would not only answer our initial problem, but one that would continue to benefit the company. Also, there are times when I need to access the technology remotely and this emulator exceeded my expectations, offering superior remote access, which is essential when a need arises to test an application quickly and securely."

"The network emulation market continues to grow in 2009 as organizations across the world are increasingly investing in placing applications on the network." Said Frank, "iTrinegy maintains its leadership position in the networked emulation market not only because of our award winning technology, but also because we continued to innovate and introduce solutions tailored for new customer needs."

INE Enterprise continues to be an important part of Dunnhumby's application network testing; it runs 24 hours a day, 7 days a week and rarely needs any maintenance. Dave says "We have found it easy to access iTrinegy's support who have been most helpful when needed. In conclusion, I can say INE Enterprise has been well worth the money and has exceeded our expectations."
