The time is right for Application Performance Engineering
The time is right for Application Performance Engineering. It’s a simple statement, but a powerful one that will change the existing application lifecycle management paradigm. At Shunra, we have been working hard, together with our partners, at developing and defining a new performance management model that completes the existing APM frameworks. This post is a [...]

Friday, March 12, 2010
The FCC just released a set of tools designed to test a user connection to the Internet,both for PC platforms (works on IE and Firefox) and applets for Iphone and other smart phones. Just access www.broadband.gov and you will be prompted to review the national plan to deploy broadband and invited to test your own [...]

Friday, March 12, 2010
Virtualization has emerged as one of the leading technologies in today’s market; enabling businesses to more effectively scale operations to meet demand while significantly reducing costs at the same time. Everyone seems to understand what virtualization is, but it’s actually rather difficult to define because the term is used interchangeably to describe a plethora of [...]

Friday, March 5, 2010
Despite Netflix’s CEO comments in a recent interview to Reuters, it is apparent that the online/rental primer distributor of movies in the US is planning to release a new service targeting, yes, you guessed correctly… millions of Iphone users. Netflix is distributing among thousands of its subscribers an online survey (see below) to float the [...]

Friday, February 19, 2010
A couple of weeks ago, I posted a blog dealing with a global study of Internet speed, where it was reported that the US is one of the few countries where the Internet is actually slowing down. On February 17, the Chairman of the FCC (Federal Communication Commission), Julius Genachowski, proposed a decade long program [...]

Monday, January 25, 2010
WAN symptoms in question are latency, packet loss, disconnects, bit errors, etc. usually exist on Wide Area Networks and as a result cause applications performance degradation. But our WAN’s essentially are LAN’s connected with each other and those connections impose geographical distance between those LANs, thus creating “WAN behavior”. Inside individual LANs those issues happen [...]

Friday, January 22, 2010
I was recently requested to support a Federal Agency that was tasked with validating the performance of an application to be globally deployed. Due to current events the timelines for testing and certification had become critical and the contractor responsible for the project was under enormous pressure to complete this engagement quickly. In conversations with [...]

Thursday, January 21, 2010
A post found today in Mashable, a blog focusing on social technology, reports that the Internet in the US is showing signs of slowing down, as measured by Aramaic, the global content provider. The performance in Q3 was bad enough to displace the US from the 10 top countries with fastest Internet access in the [...]
Continue reading...WAN Emulation vs WAN Simulation
Wednesday, December 30, 2009
One of the topics we are frequently asked is to explain or clarify the difference between WAN Emulation and WAN Simulation. WAN Simulation methodology is a set of theoretical algorithms which are usually applied on a trace file. These algorithms aim to predict applications response times with different conditions and then applied to the captured [...]

Monday, December 28, 2009
Many of the largest networks today employ Multi-Protocol Label Switching (MPLS) for a myriad of reasons. So what are some of the key motivators that would entice an organization to make the leap to MPLS? Protocol neutrality, extensibility, adaptability and scalability are among some of the many reasons. Additionally, because MPLS was designed to openly [...]
