Network Slowdown, by Design
How are you measuring your network’s performance? One can have a very fast network, but get very little throughput, with very high perceived delays…If you are using a tool, such as iperf, to measure throughput, the results can be quite deceptive. That's because iperf displays effective throughput of data at the transport layer, and thus masks what is actually going on underneath …
Are You Being Misled by Network Speed Tests? The Reality Might Surprise You!
Many "Speed Test" tools available on the Internet are easily run in a web browser. Should you trust those tools?
Not really. The popular speed testing tools provide a very narrow and limited measure of network "speed". It is quite possible that a network that is rated as "fast" could actually deliver poor results to many applications …
Deeper Implications of the Great PG&E Outage
It was 11:10pm on the night of October 9, 2019. Here along the Monterey Bay the weather was calm, cool, and a bit damp. The lights were on, the internet was working, the car was charging; everything was normal.
At 11:11pm things suddenly changed…
Application Performance Testing Mistakes
Customers abandon apps that are not responsive, according to recent studies. Two key mistakes are testing only over the local area network and having no test methodology…
Testing My App in a 5G Network
5G is the latest technology for cellular mobile communications. Deployment is expected to take place sometime between late 2019 and mid 2020. The benefits of 5G will be available to new, 5G-enabled devices. However, developers who need to know what kinds of hurdles to expect for their applications may be disappointed …
A Graphical Network Simulator for Windows
Why should I use the KMAX Network Simulator when Windows 10 has a built-in mobile network emulator? Unlike the Windows Phone Emulator, the KMAX Network Simulator emulates the network conditions that will confront all mobile devices on all types of networks (not just 3G/4G cellular), under both typical and adverse network conditions …
Understanding Network Emulators, Network Modelers, Network Simulators
Network emulators, network modelers and network simulators -- how do they differ? How do I know what solution would be right for my application? How do I compare an emulator vs a simulator? Modelers, simulators, and emulators represent a continuum, that begins with pure mathematical software models and moves towards the physical reality of emulation …
Replacing Your Shunra (now HP) Network Simulator?
Several years ago, an Israeli company called Shunra Software, offered a network simulator product. The product’s purpose: to help IT staff verify the performance of apps and devices, prior to deployment in production networks. In 2016, HPE sold the “software division”, including the HP Network Simulator, to MicroFocus.
So where does that leave HP Network Simulator? …
