In our first edition of the Spirent (formerly Mu) App Quadrant, we compared the run-time aspects of the most popular desktop video applications – Netflix, YouTube, Hulu and Amazon Video on Demand – and showed that Netflix is not particularly friendly to both Consumers and Operators. It’s not just the apps – devices matter too! Operators continue to struggle with the unpredictable growth of applications and the devices used to access them. With millions of people runni...

Video and P2P Rule! The traffic making up today’s networks is in a rapid state of flux. Just last week Sandvine, in their Spring 2011 Global Phenomena Report, noted that real-time entertainment continues to increase, and within North America represents almost 50% of peak fixed access traffic (much of this of course is due to Netflix). P2P traffic also continues to carve out a sizeable piece of the pie at around 20%. The rest is a mix of voice, business apps, games, Facebook and chat. Wha...

Our imminent next release of Spirent (formerly Mu) Studio will enable our customers to recreate 1,000,000 concurrent Netflix users watching a movie, so they can understand the impact of their application aware networks. One thing is pretty clear: compared to YouTube, Netflix inflicts so much more pain on the network....

I’ve been in the testing business for many years now and I’ve come across a lot of grandiose claims by test tool vendors with regards to features and capabilities that just sound too good to be true. And in many cases, they are. When it comes to today’s world of smartphones and tablets and the explosive growth of web and mobile applications, it’s mind-blowing to see the sheer quantity of apps out there. If you look at the number of apps available today on just three of t...

Last month we added a new space on TestCloud with thousands of known attacks as .msl templates. Some of you may recall that the secret behind the speed of test creation with Spirent (formerly Mu) is in the way we can take in a wide variety of formats including .pcap, .har, curl to name a few and convert it into MuSL. So what we did was we took another look at our known attack templates and made that available as .msl templates. ...
