Testing priorities for online, multiplayer games over the Internet…. what is the consensus opinion?

Streaming is the predominant way for people to experience music and videos, but what happens when periodic packet delay affects the streaming?

The newest Mac Minis with 10 G network interface cards have a problem when operating at 2.5 G. After several tests it became clear that the bursts of loss occurred only when the Mac Mini was running its copper network interface at 2.5Gbits/second. And only with Zoom …

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 …

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 …

We read Damien Garros' blog post -- Introduction to Network Emulation and Requirements for Virtual Network Devices with great interest as Mr. Garros takes an unusual view of networking. Our thoughts and comments follow …

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…

5G is the latest technology for cellular mobile communications. Deployment is expected to take place sometime between late 2019 and mid 2020.

It is a sensible law that will improve the security of devices on the internet. As a consequence of these new requirements IWL is making a few changes to KMAX …

Open source advocates have long proclaimed the intrinsic quality and security of open source code. They argue that because the code is open it is inspected by many eyes and tested by many hands. I dispute that argument. Code will become better through more inspection, and improved testing, no matter whether that code is "open", "free", or "proprietary" …

IWL Engineering has completed its investigation of the CVE-2018-10933 security flaw (libssh bug) and found that this bug is not present in our products. Based on testing conducted by IWL engineers, there is no indication that either Mini Maxwell or KMAX is subject to the libssh flaw. For the Maxwell Pro products, based on RedHat Fedora, RedHat has stated that its systems are not vulnerable; our testing is consistent with that …

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 …
